cURL 转 fetch 转换器

A converter that turns a curl command into equivalent JavaScript fetch code, parsing the method, URL, headers and body so you get a ready-to-use request instead of translating it by hand.

It is a common need: API docs and tools like browser devtools give you a curl command, but your app is written in JavaScript. This bridges the two so you can paste curl and get fetch.

It runs locally in your browser, so your command, including any tokens or credentials in the headers, never leaves your device.

It understands the common flags: -X for the method, -H for headers, -d and its variants for the body, -u for basic auth, plus -A for the user agent and -b for cookies. A data flag implies POST, matching how curl behaves.

Multi-line commands work as-is. Backslash line continuations are joined automatically, so you can paste a command exactly as it appears in documentation without cleaning it up first.

The output is a fetch call with the method, headers and body filled in, which you can drop into your code and await like any other fetch.
