FAQ

Q: Does my data leave my browser?

No. All processing happens locally in your browser using JavaScript. Your data is not sent to any server, ensuring privacy and security.

Q: Can it handle invalid JSON?

The tool attempts to be forgiving (e.g., stripping outer quotes), but the inner content must be valid structure-wise to be successfully parsed into JSON. If there is a syntax error, it will display a descriptive error message.

Q: What if my string has newlines as \n?

The tool correctly interprets \n as a newline character, \t as a tab, etc., restoring the original formatting of the JSON object.
