Frequently Asked Questions
Is my JSON data sent to a server?
No — processing happens entirely in your browser using JavaScript. Your data is never uploaded or stored.
What if my JSON has a syntax error?
The tool will indicate where the error occurs so you can fix issues like missing commas, unclosed brackets or trailing commas.
