JSON Formatter & Prettifier
Free online JSON formatter. Validate and pretty-print JSON with 2-space indentation, right in your browser.
How it works
The text is transformed as it is typed or pasted, with the result ready to copy from the output panel. Every transform in the switcher runs on the same input, so it is easy to try another one without re-pasting.
Everything happens in the browser. Nothing is uploaded and no request is made, which makes it safe for configuration, tokens and anything else that should not be sent to a server. Transforms that expect structured input, such as the JSON and Base64 ones, report the parse error instead of a result when the input is invalid.
