FAQ

What does a JSON formatter do?

It parses valid JSON and prints it with consistent indentation so objects and arrays are easier to read.

Does it change values?

No. Formatting only changes whitespace when the input is valid JSON.

Can I format large JSON?

Yes, but very large files depend on your browser memory.
