Convert cURL to Code - Python, JavaScript, PHP, Go

Why Convert cURL to Code?

Every developer has copied a curl command from API documentation, a browser's DevTools network tab, or a colleague's Slack message. The next step is always the same: manually translating that curl command into the language your project uses. This tool eliminates that tedious translation step.

When you right-click a network request in Chrome or Firefox DevTools and select "Copy as cURL," you get a fully formed curl command with all the headers, cookies, and authentication your browser sent. Pasting that into this converter gives you production-ready code in seconds instead of minutes spent manually mapping flags to library parameters.

How the Converter Works

The converter tokenizes your curl command while respecting quoted strings, escaped characters, and backslash line continuations. It then identifies each flag and its argument:

• -X / --request: Sets the HTTP method (GET, POST, PUT, DELETE, PATCH). If omitted and -d is present, defaults to POST.
• -H / --header: Adds a request header. Multiple -H flags are supported. The converter splits on the first colon to separate the header name and value.
• -d / --data / --data-raw: Sets the request body. Automatically implies POST if no method is specified.
• -u / --user: Basic authentication in user:password format.
• -A / --user-agent: Sets the User-Agent header.
• -b / --cookie: Sets cookies via the Cookie header.

After parsing, the converter generates idiomatic code for your chosen language, using each language's standard HTTP library conventions and best practices.

Supported Languages

Python (requests)

Generates code using the requests library, the de facto standard for HTTP in Python. Outputs clean variable assignments for URL, headers, and data, followed by the appropriate requests method call. Authentication is mapped to the auth tuple parameter.

JavaScript (fetch)

Produces modern async/await code using the Fetch API, which is available in all browsers and Node.js 18+. Headers are placed in a headers object, and the body is passed as a string. No external dependencies required.

Node.js (axios)

Generates code using axios, the most popular HTTP client for Node.js. Uses the configuration object pattern with url, method, headers, data, and auth properties.

PHP (curl)

Outputs PHP code using the native curl_* functions. Maps each curl flag to the equivalent curl_setopt call. Includes proper resource cleanup with curl_close.

Go (net/http)

Generates Go code using the standard library's net/http package. Creates an http.Request, sets headers, configures authentication, and reads the response body. No external dependencies needed.

Common Use Cases

• API integration: Copy curl examples from API docs (Stripe, Twilio, AWS) and convert to your project's language.
• Debugging reproduction: Export a failing request from DevTools as curl, then convert to code for a test case.
• Learning HTTP clients: See how the same request looks across different languages and libraries.
• Code review prep: Convert a curl one-liner into readable, structured code before committing.

Tips for Best Results

• Include the full curl command including the curl prefix.
• Multi-line curl commands with backslash continuations (\) are supported.
• Both single-quoted and double-quoted strings are handled correctly.
• If your curl command contains -H "Authorization: Bearer token123", the token will appear in the generated code. This tool runs locally, so your tokens are safe.
