Frequently Asked Questions
- What happens if my JSON is invalid?
- An error message is shown instead of a formatted result; fix the syntax and it will format automatically.
- Does this minify JSON too?
- No, this tool only pretty-prints (indents) JSON; it doesn't currently offer a minified/compact output.
