cURL to Code Converter — fetch, Axios, Python and Go
Paste a cURL command copied from Chrome DevTools, Postman or a colleague's terminal and get clean, idiomatic client code in JavaScript, Python or Go. Conversion happens entirely in your browser, so the tokens and cookies that ride along in a copied request are never uploaded.
What cURL to Code does
Your credentials stay put
A copied cURL command carries every header the browser sent — session cookies and Authorization included. Conversion runs on this page with no request and no log, which is not something a hosted converter can promise.
Mask before you share
One toggle replaces bearer tokens, API keys and passwords with a masked stub while keeping the auth scheme visible, so generated code can go straight into a ticket or a pull request.
Idiomatic, not transliterated
A JSON body becomes json= in Python and a native object in Axios — not a re-quoted string. Booleans and nulls become True and None where they should.
Real shell parsing
Quoted JSON, escaped quotes, backslash-newline continuations and joined flags such as -H'A: 1' all parse the way your shell would parse them.
Supported formats
The tool reads raw text, so whatever your stack produces will work.
How it works
Copy the request as cURL
In Chrome or Firefox DevTools, open the Network tab, right-click the request and choose Copy › Copy as cURL. Postman and Insomnia can export the same format.
Paste it here
The command is parsed as you type, and the method, host and any credential-bearing headers are summarised above the output.
Pick your language and copy
Switch between fetch, Axios, requests, httpx and Go. Tick Mask tokens first if the code is going anywhere public.

Reproducing a request in code
A request works in the browser but not in your app. Converting the exact cURL is the quickest way to find the header you forgot.
Turning API docs into a working call
Most API documentation gives examples as cURL. Convert one into the language you are actually writing in.
Sharing a repro safely
Mask the token, copy the generated snippet, and paste it into an issue without leaking a live credential.
Frequently asked questions
Is my token sent anywhere?
No. Parsing and code generation both run in JavaScript on this page — there is no upload and no server log. That said, if you pasted a live token into any tool you do not control, rotate it.
Which languages are supported?
JavaScript with the fetch API or Axios, Python with requests or httpx, and Go with net/http. Each is generated by its own emitter so the output reads like code someone would write by hand.
What happens to file uploads?
-F form fields are detected and flagged, but not converted. Multipart uploads depend on how your language reads the file from disk, and a generated guess would be more misleading than helpful.
Why does my GET turn into a POST?
That is curl's own rule: a command with -d and no explicit -X sends a POST. If you meant a query string, use -G — the converter moves the data into the URL just as curl does.
What if both -u and an Authorization header are present?
The explicit header wins, which is how curl resolves the same clash. Emitting both would produce a duplicate key that silently drops one of them.
Does the generated code handle errors?
Each snippet includes the idiomatic check for its language — response.ok, raise_for_status() or an err != nil guard — so you are not pasting in a call that fails silently.
