Frequently Asked Questions

JSON formatting (also called "pretty printing") adds proper indentation and line breaks to make raw, minified JSON human-readable.

Yes. The formatter automatically validates JSON and shows a clear error message with the line number if there is a syntax error.

Beautify adds indentation and line breaks for readability. Minify removes all whitespace to reduce file size — useful for production APIs.

The tool works entirely in your browser with no file size limit from the server side, though very large JSON files (>10 MB) may be slow depending on your device.
