How to use this tool

Paste your cURL command and choose output template style.
Review warnings and parsed breakdown for unsupported or ignored flags.
Copy or download generated fetch code and adjust edge cases manually.

Supported flags

Method and URL: -X, --request, --url.
Headers and auth: -H, -u, -b, --compressed.
Body and form: -d, --data-raw, --data-urlencode, -F/--form.

Notes

Unsupported flags are listed so you can patch output intentionally.
Multi-line commands with backslash continuations are normalized.
For advanced shell expressions, verify tokenization manually.

FAQ

Does this support file uploads in -F?: It maps -F fields to FormData entries. File-path semantics may require manual edits.
Why do I still need manual cleanup?: Complex shell interpolation, uncommon flags, and environment variables are intentionally warned rather than guessed.
Is parsing done server-side?: No. All parsing and conversion run locally in your browser.
