About JSON Validation

JSON (JavaScript Object Notation) validation is crucial for ensuring data integrity and compatibility in applications. This tool offers two types of validation:

Syntax Validation: Checks if your JSON follows the correct syntax rules and is properly formatted.
Schema Validation: Verifies that your JSON data adheres to a specific structure defined by a JSON Schema. This ensures your data not only has correct syntax but also contains the expected properties with the right data types.

Use this tool to catch errors in your JSON data before using it in your applications.
