❓ Frequently asked questions 3 answers

JSON formatting (or prettifying) adds consistent indentation and line breaks to minified or hard-to-read JSON so it's easier for humans to read and debug.

Yes. The tool handles JSON files up to your plan's file size limit. Pro users can process files up to 200 MB.

Files are processed in memory and deleted immediately after formatting. Nothing is stored long-term.
