About this tool
Pastes in messy, minified or hand-typed JSON and reformats it with clean, consistent indentation — much easier to read through and debug than a single unbroken line. If the JSON is invalid, the error message tells you roughly where the problem is, so you can find and fix a stray comma or missing bracket quickly.
