JSON formatter FAQs

What does a JSON formatter do?

A JSON formatter checks whether text is valid JSON and displays valid data with consistent indentation so it is easier to read.

Is my JSON uploaded to a server?

No. Formatting and validation run locally in your browser in this version.

Can I minify JSON?

Yes. Use the compact output option to remove unnecessary whitespace while retaining valid JSON structure.
