About this tool
cURL to Code Converter is a free, in-browser tool that turns a curl command into equivalent JavaScript fetch() code. Paste the command you copied from a terminal, an API doc or browser dev tools, and it emits a ready-to-run snippet with the URL, HTTP method, headers, request body and authentication filled in. The command is parsed as text only — it is never executed — and everything happens locally in your browser.
A quote-aware tokenizer splits the command the way a shell would, respecting single and double quotes, backslash escapes and \ line continuations, so multi-line commands and quoted JSON bodies parse correctly. It then maps the common flags: -X or --request sets the method, -H or --header builds the headers object, -d and its --data variants become the request body (which implies POST), -u or --user is encoded into a Basic Authorization header, -F or --form assembles a FormData body, and cookies, user-agent and referer flags map to their headers. Boolean flags like -L, -k and -s are ignored.
Use it to move a working curl call into a Node or browser script, to learn how a documented request maps onto the Fetch API, or to prototype against an API quickly. Because nothing is run and nothing is uploaded, you can paste commands containing tokens safely — though you should still rotate any secret you paste into a shared machine.
