cURL to Fetch

cURL to Fetch Overview

Convert cURL commands to JavaScript Fetch API

cURL to Fetch Converter is a developer-focused tool that instantly transforms raw cURL commands into clean, ready-to-run JavaScript `fetch` code. This is a massive time-saver for developers who debug network requests in browser DevTools (Network Tab) or Postman and need to replicate them in their frontend or Node.js applications. Instead of manually mapping headers, method types, and body payloads, simply paste the cURL command string, and the tool will generate the equivalent `fetch()` syntax with all options correctly formatted. It supports GET, POST, PUT, DELETE, and PATCH methods, handles complex headers (Authorization tokens, Content-Type), and parses JSON bodies automatically. Whether you are porting API calls from documentation or debugging a failing request, this converter ensures syntax accuracy and speeds up your workflow.

Frequently Asked Questions

How do I get a cURL command?
In your browser (Chrome/Edge/Firefox), open DevTools (F12), go to the "Network" tab, right-click any request, and select "Copy" > "Copy as cURL".
Does it support authentication headers?
Yes! It parses all headings including `Authorization: Bearer` tokens, API keys, and custom headers, adding them to the `headers` object in the generated code.
Does it handle POST bodies?
Absolutely. If your cURL command includes data (using -d, --data, or --data-raw), the tool will check if it's JSON and format it accordingly, or pass it as a string for other content types.
Can I use this for Node.js?
Yes, because the `fetch` API is now available native in Node.js (v18+) and widely supported in standard runtime environments, this code works in both browser and server-side JS.
Is the conversion secure?
Yes, the conversion happens entirely in your browser. Your API keys and sensitive tokens in the cURL command are never sent to our servers.
