FAQ

Can this tool validate invalid JSON?

Yes. It checks whether your JSON is valid and shows an error if the structure cannot be parsed.

Does the JSON formatter send data to a server?

No. The formatter runs in your browser, so your JSON stays on your device during normal use.

Can I use it to clean minified JSON?

Yes. It is useful for turning minified or unreadable JSON into a formatted structure that is easier to inspect.
