Beautify, validate, minify and explore JSON — free, instant, client-side.
A JSON formatter (also called a JSON beautifier or JSON pretty printer) takes raw or minified JSON and adds proper indentation and line breaks to make it human-readable. Our free online JSON formatter also validates your JSON for syntax errors and shows you exactly where the problem is.
Paste your JSON into the input panel on the left. The tool automatically validates and formats it. Switch between Formatted, Minified, and Tree views. Download the result or copy it to clipboard.
