Readable JSON without uploading data
This formatter uses the browser's built-in JSON parser. It does not transmit input to an API, which makes it suitable for ordinary development data that should stay on your device.
Formatting versus validation
Formatting succeeds only when the input is valid JSON. Property names and string values need double quotes, trailing commas are not allowed, and values such as undefined are not part of JSON.
Be careful with secrets
Local processing reduces exposure, but avoid pasting production access tokens or passwords into any browser tool. Use dedicated secret-management workflows for sensitive credentials.
