Converting cURL Commands Into JavaScript Fetch Requests

cURL commands are often used in API documentation, terminal examples, browser DevTools, and backend debugging. When you need to use the same request in JavaScript, rewriting headers, request methods, and body data manually can take extra time.

This CURL to Fetch Converter helps you convert cURL commands into JavaScript fetch code, including common headers, HTTP methods, request bodies, JSON payloads, and API request values directly in your browser.

Preparing API Requests for Frontend or Node.js Code

  1. Paste a cURL command into the input box.
  2. Click Convert to Fetch.
  3. Review the generated JavaScript fetch request.
  4. Copy the code and adjust tokens, URLs, or payload values if needed.

Common cURL to Fetch Use Cases

  • Converting API documentation examples into JavaScript code.
  • Turning browser DevTools cURL requests into fetch requests.
  • Preparing frontend API calls from tested terminal commands.
  • Checking request headers and JSON body values before coding.
  • Creating quick fetch examples for debugging or testing APIs.

Example cURL Command

curl -X POST https://api.example.com/users \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer token_here" \
  -d '{"name":"Yoryantra","role":"developer"}'
