How to use

- Choose Format for readable JSON or Minify for a compact version.
- Fix any parsing error shown below the editor.
- Copy the output when it looks right.
Good for

Can this format nested arrays and objects?
Yes. The formatter uses the browser JSON parser and preserves nested objects, arrays, booleans, numbers, and null values.
Does formatting change my JSON values?
No. Valid JSON values are parsed and serialized again, changing whitespace only.
Can I minify JSON here too?
Yes. Use the Minify button to remove extra whitespace after the JSON parses successfully.
Is my data uploaded to a server?
No. The tool runs in your browser, so the text you paste stays on your device.
