How to Use

Paste your raw JSON data into the 'Input JSON' text area on the left.
Click the "Format & Validate" button.
If the JSON is valid, it will be formatted (pretty-printed) in the 'Formatted Output' area on the right.
If the JSON is invalid, an error message will appear below the buttons indicating the issue.
Use the "Clear All" button to reset both text areas.

This tool uses your browser's built-in JSON parser for validation and formatting. Your data remains local and is not sent to any server.
