Curl to Code Converter

Convert cURL commands to JavaScript, PHP, or Python code.

Move from a copied cURL command to working code

Browser developer tools, API documentation and support tickets nearly always give examples as cURL. Rewriting each one into the language of your project by hand is tedious and easy to get wrong. The Curl to Code Converter reads a cURL command, pulls out the address, method, headers and body, and produces a starting snippet in JavaScript, PHP or Python.

Converting a command

Paste the full command into Input Data. It must begin with the word curl, otherwise the tool reports that the input must be a curl command. The Sample button loads an authenticated POST example.
Open the Target Language menu and pick JavaScript (Fetch), PHP (cURL) or Python (Requests).
Click Process Now. The generated code appears below with a line saying which language was produced.
Use Copy or Download to take the snippet away.

What gets translated

The first http or https address found in the command.
The method from an -X flag. Without one, the tool assumes POST if -d or --data is present and GET otherwise.
Every -H flag written with quotes, split at the first colon into a name and value.
A body supplied with -d in single or double quotes, or --data in single quotes.

The JavaScript output uses fetch with a headers object and chains a JSON response handler. The PHP output uses curl_init, curl_setopt calls and curl_exec. The Python output builds a headers dictionary and calls requests.request with the method and address.

Where this saves time

Copying a request from the browser Network tab as cURL and dropping it into a Node or PHP script.
Porting a vendor's cURL quick-start example into a Python integration.
Teaching or reviewing how the same request looks across three ecosystems.

Caveats

This is a basic pattern-based parser, not a full cURL implementation. Options such as -u, -F, --data-raw, --compressed, -k, cookies and multiple URLs are not interpreted, and headers or bodies that contain quote characters of the same kind as their wrapper can be cut short. The JavaScript version wraps the body in JSON.stringify, which assumes the payload is JSON, so change that if you are sending form data or plain text. Treat the output as a draft: run it, add error handling and move secrets like bearer tokens into environment variables before committing.

Frequently Asked Questions

Which languages can I generate?

Three are offered in the Target Language menu: JavaScript using the Fetch API, PHP using the cURL extension functions, and Python using the Requests library. Switch the menu and press Process Now again to see the same command in another language.

Why does it say the input must be a curl command?

The tool checks that your text starts with curl after trimming spaces. If you pasted only a URL, a header block, or included a shell prompt symbol before the command, remove it so the first word is curl.

How does it decide the HTTP method?

If your command has -X followed by an upper-case method, that value is used. Otherwise it picks POST when a -d or --data flag exists and GET when there is no body. Write -X explicitly when you need PUT, PATCH or DELETE.

Does the JavaScript output work with non-JSON bodies?

The generated fetch call wraps the body in JSON.stringify, which suits JSON payloads. For form-encoded or plain text data, edit that line to pass the raw string instead and adjust the Content-Type header accordingly.

Are all cURL flags supported?

No. It understands the URL, -X, -H, -d and --data in quoted form. Flags like -u, -F, --data-raw, -L, -k and --compressed are ignored, so add authentication or upload handling manually in the generated code.
