How to Convert a curl Command Into Code

Learn how to read a curl command and translate it into fetch, Python or PHP requests automatically.

Open the Curl-to-Code Converter

A curl-to-code converter takes a curl command and produces equivalent HTTP client code in languages like JavaScript (fetch), Python (requests), and PHP. It turns a one-off terminal request into reusable code.

How to read a curl command

A curl command starts with the URL and is followed by flags: -X sets the method, -H adds headers, -d sends a body, -u adds basic auth, and --data-urlencode encodes form data. Reading these flags is the key to translating the command into any language.

How the conversion works

The converter parses the flags into a request model — method, URL, headers, body, auth — then emits that model in the syntax of the target language. Headers become a headers object, the body becomes a JSON or form payload, and auth becomes the appropriate option for each client.

How to use the converter

  1. Paste the full curl command.
  2. Choose the target language.
  3. Copy the generated code into your project.
  4. Adjust variables like URLs or tokens as needed.

Examples

The command curl -X POST https://api.example.com/users -H "Content-Type: application/json" -d '{"name":"Jane"}' becomes a fetch call with method: "POST", headers, and a JSON-stringified body in JavaScript; a requests.post call with json= in Python; and a curl_setopt-based request in PHP — all doing the same thing.

When a curl-to-code converter is useful

  • Turning API documentation examples into app code.
  • Reproducing a working curl request in your codebase.
  • Switching languages without rewriting HTTP logic by hand.
  • Learning how a language's HTTP client maps to curl flags.
