Prettify JSON API Response

Network tabs and server logs often dump single-line JSON that is painful to read when debugging status codes and nested errors.

Paste the response body here to expand arrays and objects with readable 2-space indentation—the default many API teams prefer.

Frontend and mobile developers use it while tracing auth failures, pagination blocks, and GraphQL data envelopes during integration.

Examples (copy-paste)

Collapsed REST error payload
{"error":{"code":"RATE_LIMIT","message":"Too many requests","retry_after":30}}
Prettified for debugging
{
  "error": {
    "code": "RATE_LIMIT",
    "message": "Too many requests",
    "retry_after": 30
  }
}

FAQs

Can I prettify JSON API responses from curl output?
Yes. Copy the response body (not headers) into the input. If curl wrapped quotes, paste only the JSON object or array.
Will prettifying change field order or values?
No. Formatting only adjusts whitespace; keys and values remain identical to the parsed structure.
Are authorization tokens sent to your servers?
Never. Parsing happens in your browser, so tokens in pasted responses are not transmitted.
