How it works

Your text is parsed with the browser's built-in JSON parser. If it is valid, it is printed back with consistent indentation, or with no whitespace at all when you minify it.

When parsing fails, the parser's error message is shown so you can find the problem. Nothing you paste is uploaded or stored.
