❓ FAQ

What is JSON format?

JSON (JavaScript Object Notation) is a lightweight data exchange format that's easy to read and write for both humans and machines.

Is my data secure?

Yes! All processing happens locally in your browser. No data is ever sent to any server.

What's the difference between format and minify?

Format adds spaces and line breaks for readability. Minify removes all unnecessary whitespace to reduce file size.
