Frequently asked questions

What does a JSON formatter do?

It parses JSON data to check whether it is valid, then prints it with indentation or removes optional whitespace to minify it.

Does it change the meaning of valid JSON?

Formatting and minifying preserve JSON values, but whitespace and indentation change. Keep a copy of the original if it matters.

Can it format JavaScript objects?

It accepts strict JSON. JavaScript-only syntax such as comments, single-quoted strings, or trailing commas is invalid JSON.
