Frequently Asked Questions
Is my JSON data stored anywhere?

No. Your JSON is sent to our server only to format it, then immediately discarded — nothing is logged or saved.

Why does it say my JSON is invalid?

Common causes are trailing commas, single quotes instead of double quotes, unquoted keys, or a missing closing bracket. The beautifier validates against strict JSON syntax and reports the parse error.

Can I use this to minify JSON instead of beautifying it?

This tool focuses on pretty-printing with 2-space indentation for readability. To minify, run the output through any text tool that strips whitespace, or use it purely to validate before minifying elsewhere.
