Input JSON to validate if it is correct. Check where the errors are if it is not correct!

- Input JSON into `JSON`. - Check the result in `Result`. - If there are no errors, the error message will be displayed at the top of `Result`. - If there are errors, the lines with errors will be highlighted in red at the bottom of `Result`.

- Missing quotes - { 'name': 'john, 'age': 30 } - Missing comma - { 'name': 'john' 'age': 30 } - Parentheses mismatch - { 'name': 'john' 'age': 30

- Web application development - When using JSON for data transmission between client and server in web applications. If the JSON data sent from the client to the server is incorrect, the application detects the error and provides information on where and what the error is so the user can correct it. - API response validation - When validating the format of JSON data received as API responses in services using REST APIs. If the API response does not match the expected format, identify the problem's location and cause through error messages to debug. - Database integration - When storing or retrieving data in JSON format from a database. If the stored JSON data is corrupted or incorrectly formatted, detect and provide information on the error's location and cause for correction. - Configuration file validation - When configuration files for applications (e.g., config.json) are written in JSON format. Automatically detect syntax or formatting errors and provide information on the location and details of the error for correction. - Data exchange and integration - When using JSON for data exchange and integration between different systems. When the data format does not match or errors occur, accurately identify the location and cause of the errors to ensure data integrity.
