JSON Beautifier: Format and Indent JSON

FAQ

Is my API response sent anywhere?

Everything runs locally in your browser with JavaScript — nothing is uploaded, logged or stored. That matters when the payload contains tokens or customer records.

Can I minify instead?

Yes — the full JSON Formatter has a minify mode that strips all whitespace.
