What this curl to fetch converter does
Use this cURL converter when documentation or a terminal command needs to become a JavaScript request. It focuses on common API debugging flags and produces reviewable fetch or Axios code.
Common use cases
- Turn an API doc cURL sample into a fetch snippet.
- Convert multiline cURL copied from a terminal or bug report.
- Preserve request headers and JSON bodies for a frontend test.
- Create an Axios snippet for a quick Node or browser experiment.
Accepted input formats
Method flag
-X POST
Header flag
-H "Authorization: Bearer token"
Body flags
-d, --data, --data-raw
URL flag
--url https://api.example.com
How it works
The parser tokenizes shell-style quotes, handles common cURL flags, then emits fetch or Axios with a clear warning for unsupported flags.
Common mistakes
- Review secrets before copying generated code into a shared place.
- Some cURL features such as compressed responses, cookies, and multipart files are intentionally out of scope.
- If a command depends on shell variables, replace them with literal values before conversion.
