Fetch to cURL Converter

Converting Fetch Requests Into cURL Commands

JavaScript fetch snippets are common in frontend code, browser consoles, Node.js scripts, API examples, and debugging notes. When you need to test the same request from a terminal, converting it into cURL by hand can be annoying.

This Fetch to cURL Converter reads a fetch request and creates a cURL command with the method, URL, headers, and body. It is useful when you want to replay a request in a terminal, share a clearer API example, or debug a request outside the browser.

Turning Fetch Code Into a Terminal Request

1. Paste a JavaScript fetch request into the input box.
2. Choose multi-line or single-line cURL output.
3. Pick how the request body should be handled.
4. Hide sensitive values if you plan to share the command.
5. Copy the generated cURL command and test it in your terminal.

Common Fetch to cURL Use Cases

• Replaying a browser fetch request from the terminal.
• Turning frontend API code into a shareable cURL example.
• Debugging headers and request bodies outside the browser.
• Creating API support examples from existing JavaScript code.
• Replacing tokens and cookies with placeholders before sharing.
• Checking whether a request behaves differently in cURL and fetch.

Example Conversion

Input:
fetch("https://api.example.com/users", {
 method: "POST",
 headers: {
 "Content-Type": "application/json"
 },
 body: JSON.stringify({ name: "Yoryantra User" })
});

Output:
curl -X POST "https://api.example.com/users" \
 -H "Content-Type: application/json" \
 --data-raw '{"name":"Yoryantra User"}'

A Note About Fetch and cURL Differences

Browser fetch and cURL do not behave exactly the same. Fetch is affected by CORS, browser cookie rules, credentials settings, and frontend security behavior. cURL runs from your terminal and does not follow the same browser rules.

The generated command is a practical starting point. Review it, replace secrets, and test it against the API before using it in a script or sharing it with someone else.
