cURL to code

API documentation and browser developer tools often give you a request as a cURL command. Turning it into application code by hand means carefully copying every header, the body and authentication. This converter parses the cURL command and generates the equivalent code, so you can go from a working request to working code in seconds.

How to use it

1. Paste a cURL command. In Chrome or Firefox developer tools you can right-click a request and choose Copy as cURL.
2. Choose the target language or library.
3. Copy the generated code.

Example

Input:

curl -X POST https://api.example.com/items -H 'Content-Type: application/json' -d '{"name":"pen"}'

JavaScript fetch output:

const res = await fetch('https://api.example.com/items', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({ name: 'pen' }),
});
const data = await res.json();

What gets converted

• Method (-X), URL and query string.
• Headers (-H), including cookies.
• Body (-d, --data-raw, --data-binary) and form fields (-F).
• Basic authentication (-u user:pass).

After converting

• Remove headers copied from the browser that your code does not need, such as sec-ch-ua, accept-language and long cookie strings.
• Move tokens and API keys into environment variables instead of hard-coding them.
• Add error handling: check the response status before parsing.
• Browser fetch is subject to CORS; server-side code is not.
