cURL to Fetch
FreeConvert cURL commands to JavaScript fetch() code
fetch('https://api.x.com/users', {
method: 'POST',
headers: {
"Content-Type": "application/json"
},
body: "{"
})
.then(res => res.json())
.then(data => console.log(data));About cURL to Fetch
You copied a working cURL command from API docs, a terminal, or your browser's network tab, and now you need the same request in JavaScript. Manually translating the method, headers, and body into a fetch() call is repetitive and easy to fumble. This tool reads a cURL command and generates the equivalent fetch() code so you can paste a working request straight into your app.
Paste your cURL command and the converter maps its flags to a fetch() call: the URL, method, headers, and request body all carried over. It is free, runs in your browser, needs no signup, and returns the code instantly. It covers the common cURL options used for HTTP requests, giving you JavaScript that mirrors the original call ready to adapt.

FAQ
Which cURL flags are supported?
Common options like the method, headers, and data body are handled. Unusual flags such as advanced TLS or proxy settings may not map to fetch.
Does it handle request bodies?
Yes. Data passed with cURL's data flags becomes the body of the fetch request, with the method set accordingly.
Is the output ready to run?
It produces a fetch() call mirroring the cURL command. You may still add response handling, error handling, or await as your code needs.
Are authentication headers carried over?
Headers including Authorization are translated into the fetch headers object, so review them before sharing the generated code.
Can I use cURL to Fetch on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
