Paste a raw API response and format it as readable JSON or XML. Auto-detects format and highlights structure for debugging.
How to use this tool
Paste the API response body, choose auto or a specific format, and copy the formatted output.
Worked example
Example: a minified JSON error response becomes indented JSON with clear field names for debugging.
How it works
Paste a raw API response and the tool auto-detects JSON or XML, then pretty-prints it with readable indentation. You can force JSON or XML when auto-detection is ambiguous. Formatting works on your device.
Limitations
Processing runs on your device when possible. Verify outputs before using them in production or official submissions.
