How It Works
Uses JavaScript's built-in JSON.parse() and JSON.stringify() to validate and format your JSON safely in the browser — no data leaves your device.
- Format: Indents JSON with 2 spaces for readability
- Minify: Removes all whitespace for compact output
- Validate: Checks for syntax errors and shows error messages
