How to format JSON

Paste your JSON into the input box.
Click Beautify to pretty-print it, or Minify to strip whitespace.
If it’s invalid, you’ll see exactly what went wrong. Copy or download the result.

Does it validate JSON? Yes — formatting fails with a clear error message if the JSON isn’t valid.

Is my data private? Completely — the JSON is processed in your browser and never uploaded.
