What does a cURL to code converter do?

It reads a curl command, breaks it into its parts (HTTP method, URL, headers, request body, authentication) and rewrites that same request as code in your chosen language. Instead of hand-translating flags like -X, -H and -d, you paste once and get idiomatic fetch, axios, Python requests, httpx, PHP cURL, Node https or Go code that makes the identical request.

Which curl flags are supported?

The parser understands -X/--request, -H/--header, -d/--data, --data-raw, --data-binary, --data-urlencode, -F/--form (including @file uploads), -u/--user for basic auth, -b/--cookie, -L/--location, -k/--insecure and -G. Cosmetic or transport-only flags such as -s, --compressed, --max-time and -o are recognised and safely ignored, with a note listing anything dropped.

Does it handle JSON request bodies correctly?

Yes. When the body is JSON it is pretty-printed and emitted as a real object literal — JSON.stringify in JavaScript, a Python dict for requests/httpx, a PHP associative array passed through json_encode, and a raw string reader in Go. If you send JSON without a Content-Type header the tool detects it and assumes application/json, flagging the assumption.

Is my command or any data sent to a server?

No. Parsing and code generation happen entirely in your browser with JavaScript. Your curl command, API keys, tokens and request bodies never leave your device — there is no network request, no logging and no upload. Your last input is saved only in your own browser via localStorage so it is still there when you return.

Can it convert browser DevTools "Copy as cURL" output?

Yes. Right-click any request in the Network tab of Chrome, Firefox or Edge, choose Copy then Copy as cURL, and paste it here. Multi-line commands with backslash line continuations, single and double quotes, and long header lists are all handled, so you get working client code from a real captured request.

Why would I convert curl instead of just running it?

curl is perfect for quick terminal testing, but production apps make requests from JavaScript, Python, PHP or Go. Converting lets you move a verified request straight into your codebase without re-typing headers or re-escaping a JSON body, and it documents an API call in a language your team actually ships.

cURL to Code Converter

A cURL to code converter that turns any curl command into ready-to-run client code. Paste a command copied from your terminal, an API’s documentation, or your browser’s “Copy as cURL” menu, and the tool parses every flag — the HTTP method, the URL and query string, each header, the request body, and basic authentication — then rewrites the exact same request as fetch, axios, Node https, Python requests, Python httpx, PHP cURL, or Go net/http code. It is for developers who test an endpoint with curl and then need that call inside a real application without hand-translating a wall of -H and -d flags.

How it works

The converter runs a small shell-aware tokeniser over your command. It respects single and double quotes, backslash line continuations (the trailing \ that wraps a long curl command across multiple lines), and the limited set of escapes a POSIX shell applies inside double quotes. The resulting arguments are parsed into a structured request: method, URL, an ordered list of headers, the body, any -F form fields (including @file uploads), and -u basic-auth credentials.

From that structured request, each language generator emits idiomatic code. A JSON body is pretty-printed and rendered as a native object — a JavaScript object literal wrapped in JSON.stringify, a real Python dict, a PHP associative array, or a string reader in Go. URL-encoded bodies become URLSearchParams, a Python data= dict, or http_build_query. Multipart uploads map to FormData, Python files=, or PHP CURLFile. Transport-only flags such as --max-time, --compressed and -s are recognised and skipped, and every dropped or inferred detail is surfaced as a warning so nothing changes silently.

Example

Take a typical POST with a JSON body:

curl -X POST 'https://api.example.com/v1/orders' \
  -H 'Authorization: Bearer sk_test_abc123' \
  -H 'Content-Type: application/json' \
  --data-raw '{"item":"widget","qty":3}'

The fetch output sets the method, copies both headers into a headers object, and emits body: JSON.stringify({ item: "widget", qty: 3 }). Switch to the Python requests tab and the same body becomes json={'item': 'widget', 'qty': 3} with a matching headers dict; the PHP tab builds a CURLOPT_HTTPHEADER array and json_encodes the payload. Every tab makes the identical HTTP request — only the language differs.

Everything is computed in your browser. Your command, tokens and request bodies are never uploaded, logged or stored on any server.
