What does the JSON formatter do?

It prettifies minified JSON with proper indentation, validates it for syntax errors, and lets you minify, sort keys, or explore the structure in a tree view.

Can it validate JSON?

Yes. The tool highlights any syntax errors with the line number and a description so you can fix them quickly.

Can I convert JSON to CSV?

Yes. The tool includes a JSON to CSV converter for flat JSON arrays.

Is my JSON data sent to a server?

No. All formatting and validation happens in your browser. No data is sent to any server.
