Json validator linux

To solve the problem of validating JSON on Linux, here are the detailed steps:

JSON (JavaScript Object Notation) is a lightweight data-interchange format, widely used for data transmission in web applications. Ensuring your JSON data is syntactically correct and adheres to a defined structure (schema) is crucial for reliable system interactions. On a Linux system, you have several powerful command-line tools at your disposal for this very purpose.

Basic JSON Validation:

1. Using jq (J-Query for JSON): This is the go-to tool for parsing, filtering, and manipulating JSON. For basic validation, simply pipe your JSON content into jq. If jq can parse it and pretty-print it without errors, your JSON is syntactically valid.
   • Command: echo '{"key": "value"}' | jq .
   • Output (valid):

     {
       "key": "value"
     }
     

   • Command (invalid): echo '{"key": "value",}' | jq .
   • Output (invalid):

     parse error: trailing comma after object value at line 1, column 19
     

2. Using python -m json.tool: Python’s built-in json.tool module is another excellent option for quick validation and pretty-printing.
   • Command: echo '{"data": [1, 2, 3]}' | python -m json.tool
   • Output (valid):

     {
         "data": [
             1,
             2,
             3
         ]
     }
     

   • Command (invalid): echo '{"data": [1, 2, 3' | python -m json.tool
   • Output (invalid):

     Expecting ']' delimiter: line 1 column 18 (char 17)
     

3. Using jsonlint (Node.js based): If you have Node.js installed, jsonlint is a robust command-line validator.
   • Installation: npm install -g jsonlint (Requires Node.js and npm)
   • Command: echo '{"status": "ok"}' | jsonlint
   • Output (valid): (No output for valid JSON, just exits with status 0)
   • Command (invalid): echo '{"status": "ok' | jsonlint
   • Output (invalid):

     Error: Parse error on line 1:
     {"status": "ok'
                 --^
     Expecting 'STRING', 'NUMBER', 'NULL', 'TRUE', 'FALSE', '{', '['
     

JSON Schema Validation (for structural validation):
For more advanced validation, where you need to ensure your JSON conforms to a specific structure, data types, and constraints defined by a JSON Schema, you’ll need a dedicated JSON Schema validator Linux.

1. Using jsonschema-cli (Python based): This is a popular and straightforward tool for validating JSON against a schema.
   • Installation: pip install jsonschema-cli (Requires Python and pip)
   • Create example files:
     • valid_json_example.json:

       {
         "name": "Ali",
         "age": 30,
         "isStudent": false
       }
       

     • simple_schema.json:

       {
         "type": "object",
         "properties": {
           "name": {"type": "string"},
           "age": {"type": "integer", "minimum": 0},
           "isStudent": {"type": "boolean"}
         },
         "required": ["name", "age"]
       }
       

   • Command (valid): jsonschema -i valid_json_example.json simple_schema.json
   • Output (valid): (No output for valid JSON, just exits with status 0)
   • Command (invalid – missing required field): Let’s modify valid_json_example.json to remove “age”:

     {
       "name": "Ali",
       "isStudent": false
     }
     

     Then run: jsonschema -i valid_json_example.json simple_schema.json

   • Output (invalid):

     'age' is a required property
     Failed to validate
     

These tools provide robust methods for ensuring your JSON data integrity on Linux, from simple syntax checks to complex schema adherence.

Understanding JSON Validation on Linux

JSON (JavaScript Object Notation) has become the de facto standard for data exchange across modern applications, microservices, and APIs. Its simplicity and human-readable format make it incredibly versatile. However, with this flexibility comes the critical need for validation. Without proper validation, malformed or unexpected JSON data can lead to application crashes, security vulnerabilities, or incorrect processing. On Linux, a powerful ecosystem of command-line tools provides robust solutions for both basic syntax checking and advanced schema-based validation. Mastering these tools is essential for developers, system administrators, and anyone dealing with data pipelines.

Why Validate JSON?

JSON validation isn’t just a best practice; it’s a necessity for robust and secure systems. Think of it as a quality control checkpoint for your data. A small syntax error, like a missing comma or an unescaped character, can completely break an application that expects perfectly formed JSON. Beyond syntax, ensuring data adheres to a predefined structure (via a JSON Schema) prevents logical errors and inconsistencies, ensuring that, for instance, an “age” field is always a positive integer and not a string. This becomes even more critical in distributed systems where data might flow from various sources.

Basic JSON Syntax Validation with jq

When you’re working on the Linux command line, the jq utility is your Swiss Army knife for anything JSON-related. It’s not just a parser; it’s a powerful processor that can slice, dice, filter, and transform JSON data. Crucially, its core function involves parsing JSON, and if it can parse it successfully, it confirms the JSON’s syntactic validity. If there’s an error, jq will report it immediately, often with helpful line and column numbers.

Installation and Usage of jq

Most modern Linux distributions include jq in their repositories, making installation straightforward.

• Debian/Ubuntu: sudo apt update && sudo apt install jq
• CentOS/RHEL/Fedora: sudo yum install jq or sudo dnf install jq
• Arch Linux: sudo pacman -S jq

To use jq for basic validation, you simply pipe your JSON string or file content into it. The simplest operation is jq ., which pretty-prints the input JSON. If the JSON is valid, it will be formatted nicely. If it’s invalid, jq will output an error message to stderr and exit with a non-zero status code (typically 4), which is excellent for scripting. Json max number

Example 1: Valid JSON

echo '{"message": "Hello, World!", "version": 1.0}' | jq .

Output:

{
  "message": "Hello, World!",
  "version": 1
}

Example 2: Invalid JSON (missing closing brace)

echo '{"message": "Hello, World!"' | jq .

Output:

parse error: Expected another key-value pair, or the end of the object at line 1, column 28

You can also validate JSON from a file: Json minify java

# Create a valid JSON file
echo '{"product": "Laptop", "price": 1200.00, "inStock": true}' > product.json

# Validate it
jq . product.json

If you only care about validity and not the pretty-printed output, you can redirect stdout to /dev/null and check the exit status:

echo '{"name": "Valid JSON"}' | jq . > /dev/null && echo "JSON is valid." || echo "JSON is invalid."

This script will output “JSON is valid.” if the input is correct, and “JSON is invalid.” otherwise. jq is incredibly fast, making it suitable for validating large JSON files or streams. For instance, processing a 100MB JSON file typically takes milliseconds on modern hardware.

Leveraging Python’s json.tool for Quick Checks

Python, being a ubiquitous language on Linux systems, provides a built-in module json that includes a command-line tool for basic JSON operations: json.tool. While jq is generally more powerful for complex transformations, json.tool offers a very convenient way to validate and pretty-print JSON without installing any additional packages if Python is already present.

How to Use python -m json.tool

The json.tool module can be invoked directly from the command line using the -m flag. Similar to jq, it expects JSON input via standard input (stdin) and outputs pretty-printed JSON to standard output (stdout). If the input JSON is malformed, it will print a json.JSONDecodeError message to stderr and exit with a non-zero status.

Example 1: Valid JSON Json escape online

echo '{"city": "Mecca", "country": "Saudi Arabia"}' | python -m json.tool

Output:

{
    "city": "Mecca",
    "country": "Saudi Arabia"
}

Example 2: Invalid JSON (syntax error: single quotes instead of double quotes for keys/strings)

echo "{'item': 'book'}" | python -m json.tool

Output:

Expecting property name enclosed in double quotes: line 1 column 2 (char 1)

You can also pass a file directly to json.tool:

# Create a JSON file
echo '{"tool": "python", "module": "json.tool"}' > tool_info.json

# Validate and pretty-print
python -m json.tool tool_info.json

Output: Json prettify sublime

{
    "tool": "python",
    "module": "json.tool"
}

For basic, quick syntax checks, python -m json.tool is an excellent, dependency-free option for any Linux system with Python installed. It’s particularly handy in scripting scenarios where you’re already using Python for other tasks. According to a Stack Overflow survey, Python is one of the most widely used programming languages, making json.tool readily available on countless Linux machines.

Advanced Validation with JSON Schema

While jq and python -m json.tool are great for syntax checks, they don’t verify the structure or data types of your JSON. This is where JSON Schema comes in. JSON Schema is a powerful standard for describing the structure of JSON data. It allows you to define constraints like:

• Data types: Is a field a string, number, boolean, array, or object?
• Required fields: Which fields must be present?
• Min/max values: For numbers or string lengths.
• Patterns: For string formats (e.g., email, UUID, date-time).
• Enum values: A field must be one of a predefined set of values.
• Array items: What type of items an array can contain, and how many.

Validating JSON against a schema ensures that your data adheres to a contract, which is invaluable for API design, data serialization, and robust data processing pipelines.

JSON Schema Validator Linux Tools

On Linux, several tools can perform JSON Schema validation. The most common and recommended approach involves Python-based libraries due to their maturity and ease of installation via pip.

1. jsonschema-cli (Python)

The jsonschema-cli package provides a straightforward command-line interface for the popular jsonschema Python library. It’s robust, well-maintained, and supports various JSON Schema draft versions (e.g., Draft 07, Draft 2020-12). Html minify to normal

Installation:
Ensure you have pip installed, then run:

pip install jsonschema-cli

It’s often a good practice to install Python packages in a virtual environment to avoid conflicts with system-wide packages.

Usage:
The basic usage is jsonschema -i <instance_json_file> <schema_json_file>.

Example:
Let’s define a simple schema for user profiles:
user_schema.json:

{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "title": "User Profile",
  "description": "Schema for a user's basic profile information.",
  "type": "object",
  "properties": {
    "userId": {
      "type": "string",
      "pattern": "^[a-f0-9]{8}-[a-f0-9]{4}-[a-f0-9]{4}-[a-f0-9]{4}-[a-f0-9]{12}$",
      "description": "Unique identifier for the user (UUID format)."
    },
    "username": {
      "type": "string",
      "minLength": 3,
      "maxLength": 50,
      "description": "The user's chosen username."
    },
    "email": {
      "type": "string",
      "format": "email",
      "description": "The user's email address."
    },
    "age": {
      "type": "integer",
      "minimum": 13,
      "description": "The user's age, must be 13 or older."
    },
    "preferences": {
      "type": "object",
      "properties": {
        "darkMode": {"type": "boolean"},
        "language": {"type": "string", "enum": ["en", "es", "ar"]}
      },
      "additionalProperties": false,
      "description": "User preferences."
    }
  },
  "required": ["userId", "username", "email", "age"],
  "additionalProperties": false
}

Now, let’s create a valid JSON instance and an invalid one.
valid_user.json: Html prettify sublime

{
  "userId": "a1b2c3d4-e5f6-7890-1234-567890abcdef",
  "username": "JannahUser",
  "email": "[email protected]",
  "age": 25,
  "preferences": {
    "darkMode": true,
    "language": "ar"
  }
}

invalid_user.json (missing email, invalid age, extra field):

{
  "userId": "z9y8x7w6-v5u4-3210-9876-543210fedcba",
  "username": "short",
  "age": 10,
  "extraField": "should not be here"
}

Running Validation:

• Valid instance:

  jsonschema -i valid_user.json user_schema.json
  

  Output: (No output, exits with status 0, indicating success)

• Invalid instance:

  jsonschema -i invalid_user.json user_schema.json
  

  Output:

  'email' is a required property
  10 is less than the minimum of 13
  Additional properties are not allowed ('extraField' was unexpected)
  Failed to validate
  

  jsonschema-cli provides clear, concise error messages, making it easy to pinpoint validation failures. This level of detail is crucial for debugging data issues, especially in complex systems like microservices architectures, where a single data record might pass through several validation layers.

2. Other JSON Schema Validators

While jsonschema-cli is excellent, other options exist depending on your language ecosystem:

• Go: For Go developers, libraries like go-jsonschema (though often used programmatically) might have command-line wrappers or be used to build custom CLI tools.
• Node.js: Tools like ajv-cli (built on top of the ajv library, known for its performance) can be installed via npm (npm install -g ajv-cli).
  • Usage: ajv validate -s user_schema.json -d invalid_user.json -v
  • ajv is reportedly one of the fastest JSON Schema validators, making it a good choice for high-throughput environments. A benchmark from 2023 showed ajv processing thousands of validations per second.

Choosing the right JSON Schema validator depends on your existing toolchain and performance requirements. For most Linux users, jsonschema-cli offers the best balance of ease of use and comprehensive validation capabilities. Html minifier terser

Scripting JSON Validation Workflows

The real power of these command-line tools shines when integrated into shell scripts, CI/CD pipelines, or automated data processing workflows. By leveraging their exit codes, you can build robust validation steps that halt execution if data integrity is compromised.

Example: Automated JSON Configuration Validation

Imagine you have a config.json file that dictates your application’s behavior, and you want to ensure it always adheres to a specific config_schema.json.

config_schema.json:

{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "type": "object",
  "properties": {
    "databaseUrl": {"type": "string", "format": "uri"},
    "port": {"type": "integer", "minimum": 1024, "maximum": 65535},
    "debugMode": {"type": "boolean"},
    "logLevel": {"type": "string", "enum": ["info", "warn", "error"]}
  },
  "required": ["databaseUrl", "port", "debugMode", "logLevel"]
}

app_config.json (example valid config):

{
  "databaseUrl": "postgresql://user:pass@host:5432/db",
  "port": 8080,
  "debugMode": false,
  "logLevel": "info"
}

Now, let’s create a validation script validate_config.sh: Html encode special characters

#!/bin/bash

CONFIG_FILE="app_config.json"
SCHEMA_FILE="config_schema.json"

echo "--- Validating $CONFIG_FILE against $SCHEMA_FILE ---"

# First, a basic syntax check with jq
echo "Step 1: Basic JSON syntax check with jq..."
jq . "$CONFIG_FILE" > /dev/null
if [ $? -ne 0 ]; then
    echo "❌ Basic JSON syntax error in $CONFIG_FILE. Aborting."
    exit 1
fi
echo "✅ Basic JSON syntax is valid."

# Second, JSON Schema validation with jsonschema-cli
echo "Step 2: JSON Schema validation with jsonschema-cli..."
jsonschema -i "$CONFIG_FILE" "$SCHEMA_FILE"
if [ $? -ne 0 ]; then
    echo "❌ JSON Schema validation failed for $CONFIG_FILE. Please fix it."
    exit 1
fi

echo "✅ All validations passed. $CONFIG_FILE is valid and conforms to schema."
exit 0

This script first performs a quick syntax check with jq. If that passes, it proceeds to the more rigorous schema validation. By checking the $? (exit status of the last command), the script can gracefully exit early if an error is detected. This two-step process provides both immediate feedback on basic issues and detailed reports on structural problems.

This type of script can be integrated into:

• Git pre-commit hooks: To prevent invalid JSON from ever being committed to your repository.
• CI/CD pipelines (e.g., GitHub Actions, GitLab CI, Jenkins): To automatically validate configuration files or data payloads before deployment or processing.
• Daily cron jobs: For regular health checks on data files or system configurations.

According to a 2023 report by the Cloud Native Computing Foundation (CNCF), over 90% of organizations are now using containers, and JSON configuration files are a cornerstone of containerized applications. Automated validation is thus more important than ever.

Handling Large JSON Files

When dealing with extremely large JSON files (gigabytes in size), direct piping or reading the entire file into memory for validation can be problematic. While jq is generally memory-efficient and streams data, other tools might struggle.

Strategies for Large Files:

1. Stream Processing with jq: jq excels at stream processing. For basic validation, it can often handle large files without issues. If you just need to confirm validity, piping to jq . is usually sufficient.

   cat large_data.json | jq . > /dev/null
   

2. Splitting Large Files: If your large JSON file is an array of objects, and you need to validate each object against a schema, you might split the file into smaller chunks.
   • Using jq -c '.[]' to output each array element as a compact JSON line.
   • Then, you could potentially process each line. However, direct schema validation on streamed array elements with jsonschema-cli might be less straightforward, as it expects a full JSON instance.
   • For example, if large_array.json is [{}, {}, ...]:

     # This will output each object on a new line
     jq -c '.[]' large_array.json > objects_per_line.json
     

     You’d then need a custom script to read each line from objects_per_line.json and validate it individually. This is more complex but necessary for memory-constrained environments.

3. Using grep for quick sanity checks: For specific, simple checks (e.g., ensuring a certain key exists in the first few lines), grep can provide a super-fast initial scan, though it’s not a full validator.

   head -n 100 large_data.json | grep -q '"someKey":' && echo "Key found in head"
   

4. Dedicated Streaming Parsers/Validators: For truly massive files and continuous data streams, consider specialized tools or libraries designed for streaming JSON parsing, such as ijson in Python, which does not load the entire file into memory. While ijson doesn’t directly offer a command-line validation tool, you could easily write a Python script using it and jsonschema library for streaming schema validation.

Real-world datasets, especially in big data environments, can often be hundreds of gigabytes or even terabytes. Efficient handling of these datasets requires tools and strategies that minimize memory footprint and optimize I/O. Html encode c#

Best Practices for JSON Validation

To ensure robust and maintainable systems, consider these best practices when implementing JSON validation on Linux:

• Validate Early, Validate Often: Perform validation as early as possible in your data pipeline. This means validating incoming API requests, configuration files at startup, and data payloads before processing. Catching errors early reduces debugging time and prevents corrupt data from propagating through your system.
• Use JSON Schema for Structural Integrity: For anything beyond basic syntax checks, invest time in defining clear JSON Schemas. Schemas serve as living documentation and enforce data contracts, which are invaluable for teams collaborating on APIs or data formats.
• Automate Validation: Integrate validation into your CI/CD pipelines, Git hooks, and automated scripts. Manual validation is prone to human error and doesn’t scale.
• Provide Clear Error Messages: When validation fails, ensure your tools or scripts provide actionable error messages. Tools like jsonschema-cli do this well by default, indicating what went wrong and where.
• Version Your Schemas: As your data structures evolve, so too should your schemas. Versioning your schemas (e.g., v1, v2) allows for graceful transitions and backward compatibility management.
• Consider Performance: For high-throughput systems, choose validators known for their performance (e.g., ajv in Node.js, or compiled language libraries). Benchmarking with your typical data sizes is crucial.
• Don’t Over-Validate (Initially): While comprehensive schemas are good, start with the most critical constraints. You can always add more detailed validation rules as your understanding of data requirements matures. Don’t let perfect be the enemy of good when setting up your first validation steps.

By adopting these practices, you can significantly improve the reliability and maintainability of your applications and data pipelines, ensuring that your JSON data is always in the correct shape.

FAQ

Is there a built-in JSON validator in Linux?

No, Linux distributions do not come with a single, universally “built-in” JSON validator. However, they typically provide tools like jq or python -m json.tool that can perform basic JSON syntax validation as part of their functionality, often pre-installed or easily installable from official repositories.

How do I validate a JSON file on the command line?

To validate a JSON file on the command line, you can use jq by piping the file content into it: cat your_file.json | jq .. If jq outputs formatted JSON, it’s valid. Alternatively, use python -m json.tool your_file.json. Both will exit with a non-zero status and print an error if the JSON is malformed.

What is jq and how does it help with JSON validation?

jq is a lightweight and flexible command-line JSON processor. It helps with JSON validation because its primary function is to parse JSON. If jq can successfully parse and process your input (e.g., pretty-print it with jq .), then your JSON is syntactically valid. If there’s an error in the JSON structure, jq will report a parsing error. Html encode string

How can I validate JSON against a schema on Linux?

To validate JSON against a schema on Linux, you typically need a dedicated JSON Schema validator. The most common and recommended tool is jsonschema-cli (Python-based). After installing it with pip install jsonschema-cli, you can validate using jsonschema -i your_data.json your_schema.json.

Can I use jsonlint for JSON validation on Linux?

Yes, you can use jsonlint for JSON validation on Linux. jsonlint is a command-line utility for validating JSON syntax. It’s typically installed via Node.js’s package manager (npm install -g jsonlint). You can then pipe JSON into it: echo '{"data": "value"}' | jsonlint. It will silently succeed for valid JSON and report errors for invalid JSON.

What’s the difference between basic JSON validation and JSON Schema validation?

Basic JSON validation (e.g., with jq or python -m json.tool) only checks if the JSON syntax is correct and well-formed. JSON Schema validation, on the other hand, checks if the JSON data adheres to a predefined structure, data types, and constraints specified in a separate JSON Schema document. It verifies the meaning and structure of the data, not just its syntax.

Is python -m json.tool reliable for large JSON files?

python -m json.tool is generally reliable for validating JSON files, but for extremely large files (multiple gigabytes), it might consume a lot of memory as it typically loads the entire file into memory. For such cases, stream-oriented tools or custom scripts using streaming JSON parsers (like Python’s ijson library) would be more efficient.

How do I install jsonschema-cli on Ubuntu/Debian?

First, ensure you have pip installed: sudo apt update && sudo apt install python3-pip. Then, install jsonschema-cli using pip: pip install jsonschema-cli. It’s often recommended to use a Python virtual environment to manage dependencies. Url parse nodejs

Can I validate JSON in a shell script and check the result?

Yes, you can validate JSON in a shell script by checking the exit status of the validation command. Most command-line JSON validators (like jq or jsonschema-cli) return an exit status of 0 for success and a non-zero value (e.g., 1 or 4) for failure. You can use $? in Bash to check the exit status:

jq . your_file.json && echo "Valid" || echo "Invalid"

What are some common JSON syntax errors that validators catch?

Common JSON syntax errors that validators catch include:

• Missing commas between key-value pairs or array elements.
• Trailing commas (JSON doesn’t usually allow them, unlike JavaScript).
• Using single quotes instead of double quotes for keys or string values.
• Unescaped special characters within strings.
• Missing opening or closing braces {} or brackets [].
• Incorrectly formatted numbers (e.g., leading zeros).

Can I pretty-print JSON and validate it simultaneously on Linux?

Yes, tools like jq . and python -m json.tool inherently pretty-print valid JSON while also performing a syntax validation. If the JSON is valid, it will be formatted nicely; if not, an error will be displayed instead of the formatted output.

Are there any GUI JSON validators for Linux?

While the focus is on command-line tools, many graphical text editors (like VS Code, Sublime Text, Atom) offer extensions for JSON validation and formatting. Additionally, web-based JSON validators can be accessed through a browser on Linux, providing a graphical interface.

How can I integrate JSON validation into my CI/CD pipeline?

You can integrate JSON validation into your CI/CD pipeline by adding steps to your CI/CD configuration (e.g., gitlab-ci.yml, github_actions.yml). These steps would execute command-line validators like jsonschema -i config.json schema.json. If the validation command exits with a non-zero status, the pipeline step will fail, preventing deployment of invalid configurations or data. Url parse deprecated

Is JSON Schema difficult to learn?

JSON Schema has a learning curve, but its core concepts are relatively straightforward. Starting with basic types, properties, and required fields is easy. More advanced features like allOf, anyOf, oneOf, and custom formats require a deeper understanding. Numerous online resources and examples can aid in learning.

What is a “valid json example” for basic understanding?

A valid JSON example:

{
  "name": "Khaled",
  "age": 35,
  "isMuslim": true,
  "hobbies": ["reading Quran", "charity work", "hiking"],
  "address": {
    "street": "123 Peace Lane",
    "city": "Madinah",
    "zipCode": "14001"
  },
  "contact": null
}

This example shows an object with strings, numbers, booleans, an array, a nested object, and a null value, all correctly formatted.

Why would a JSON validator say my JSON is invalid when it looks correct?

Even if JSON “looks” correct to a human, it might be invalid due to subtle errors:

• Trailing commas: A common mistake in JavaScript that is invalid in strict JSON.
• Single quotes: JSON strictly requires double quotes for all keys and string values.
• Unescaped special characters: Characters like " or \ within a string must be escaped (\", \\).
• Comments: JSON does not support comments (unlike JavaScript). If you include // or /* */, it will be invalid.
• Incorrect nesting: Mismatched braces or brackets.

Can JSON validators help with debugging API responses?

Absolutely! JSON validators are invaluable for debugging API responses. If an API is returning malformed JSON, a validator will immediately flag it, helping you identify if the problem lies with the API server (sending bad data) or your client (misinterpreting the data). This saves significant debugging time. Url decode c#

What are alternatives to jsonschema-cli for JSON Schema validation on Linux?

While jsonschema-cli is robust, other options for JSON Schema validation on Linux include:

• ajv-cli (Node.js based): Known for its performance.
• Custom scripts: You can write small scripts in Python, Go, or Node.js using their respective JSON Schema libraries (e.g., Python’s jsonschema, Go’s go-jsonschema, Node.js’s ajv) to perform validation programmatically.

How can I ensure my JSON data is both valid and conforms to a standard structure?

To ensure your JSON data is both syntactically valid and conforms to a standard structure, you should use a two-pronged approach:

1. Syntax Validation: Use tools like jq or python -m json.tool for the initial check to ensure it’s well-formed JSON.
2. Schema Validation: Use a JSON Schema validator Linux tool like jsonschema-cli to validate the data against a predefined JSON Schema, enforcing its structure, data types, and constraints. This combined approach provides comprehensive data integrity assurance.

Is it possible to get detailed error reports from JSON validators?

Yes, most robust JSON validators, especially JSON Schema validators, provide detailed error reports.
