The frame below runs the same code as this page, in the reader's own browser. Nothing is sent to us, and nothing is sent to you.

Pick a dark background and the text and panels follow it, so the frame stays readable on a dark page.

How it works

A response body is parsed as JSON, then reserialized with indentation, sorted keys, or compact separators while status, headers, and body remain separate. Invalid JSON is reported rather than silently repaired.

  • Two-space output suits debugging.
  • Compact mode mirrors transport serialization.

Worked example

Format JSON API Response
Pretty-print a minified JSON API response with 2-space indentation
Input
											{"id":1,"name":"Alice","email":"[email protected]","roles":["admin","user"]}
Output
												{
  "id": 1,
  "name": "Alice",
  "email": "[email protected]",
  "roles": [
    "admin",
    "user"
  ]
}

When to use this

Support captures, API snapshots, and documentation examples format responses.

Edge cases

  • Large numbers can lose precision during JavaScript parsing.
  • Duplicate JSON keys are ambiguous.
  • A 204 response can have an empty body rather than JSON.
