Is this tool free?+
Yes. The JSON formatter and validator is completely free. Paste any JSON to format, minify, or validate it.
Do I need to sign up?+
No. No signup, no account, no email. Just paste your JSON and go.
Is my data private?+
Your JSON never leaves your browser. Parsing, formatting, and syntax highlighting all happen in JavaScript on your device. Nothing is uploaded to any server.
What happens if my JSON is invalid?+
The tool shows the exact character position where the parse error occurs, so you can find and fix the problem quickly.
