Frequently asked questions
Is it safe to paste sensitive data here?
Yes. All processing happens in your browser with JavaScript; the data is never sent to or logged on any server.
Why does my JSON throw a syntax error?
The most common causes are trailing commas, single quotes instead of double, or unquoted keys. The tool marks the line and column of the failure so you find it instantly.
