Frequently Asked Questions

What is the difference between formatting and minifying?expand_more

Formatting adds whitespace and line breaks to make JSON easier to read. Minifying removes unnecessary characters so the payload is smaller and denser.

Does this validator check strict JSON syntax?expand_more

Yes. Invalid commas, malformed quotes, and other syntax errors are detected immediately before formatting runs.
