Frequently Asked Questions

Does the JSON formatter also validate my JSON?

Yes, if your JSON is malformed (e.g., missing a comma or bracket), the tool will flag the error to help you fix it.

Can I minify JSON to reduce file size?

Yes, in addition to 'beautifying' (adding indentation), you can 'minify' the JSON by removing all unnecessary whitespace.
