API Response Formatter

Browser-based
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 runs entirely in your browser.
Limitations
Processing runs in your browser when possible. Verify outputs before using them in production or official submissions.
Privacy and file handling
Your data is processed in your browser and is not uploaded to our server.
