Worked examples

Use this when inspecting structured input or preparing a data or code artifact. Generated commands and configurations remain text until you review and use them yourself.

Reproducible worked example

Settings: No additional settings.

Input:

{"method":"GET","url":"https://example.com/api?q=1","headers":{"Accept":"application/json"}}

With the input and settings above, the tool produces:

Output:

GET /api?q=1 HTTP/1.1
Host: example.com
Accept: application/json

The example output has 3 lines. Compare its order, separators and whitespace with the input before copying the result.

Limitations and common mistakes

  • Text request draft only. No request is sent, and bodies/framing headers are intentionally excluded.
  • Combined input is bounded to 150,000 characters; output text is bounded to 1.2 million characters. Some algorithms impose smaller limits, stated in their error messages.
