Curl to Fetch Converter Online

Almost every API documentation site (like Stripe or Twilio) gives you code examples formatted as raw cURL commands. If you are building a frontend React or Vanilla JS app, manually translating those -H headers and -d data payloads into a proper JavaScript fetch() object is incredibly tedious. This parser is built to do it automatically.

Regex Extraction

When you paste a terminal command here, the regex engine intelligently dissects the flags. It looks for -X or --request to define the HTTP method (GET, POST, PUT, DELETE). It extracts all -H strings and maps them into a clean JavaScript Headers object. Finally, if it detects a JSON payload attached to a -d flag, it automatically injects JSON.stringify() into the generated body parameter.

Limitations

cURL is a massive command-line utility with hundreds of obscure flags. This specific parser is optimized for standard REST API requests. If you are using advanced flags for SSL certificate bypassing, proxy routing, or multi-part file chunking, the JS fetch() translation will likely drop those complex parameters.

Execution Safety

This tool is purely a text converter. It does NOT actually execute the network request. It simply translates the syntax so you can paste the resulting code into your IDE.
