How this page works
Use this page to expand compact JSON into a readable structure with indentation. This is useful when JSON is technically valid but hard to inspect because everything is on one line.
The tool parses the JSON first, then prints it back in a clean format. If the input is malformed, it will show an error instead of pretending the data was formatted.
