cURL to Code Converter

Code

Convert a cURL command into Python requests, JavaScript fetch, or Node.js axios code instantly. Paste any cURL command and get working code in your language.

What is a cURL→Code?

A cURL to Code Converter translates a cURL command — the format most API documentation and browser developer tools use to describe an HTTP request — into working code in Python, JavaScript, or Node.js. cURL commands are a convenient universal format for describing a request (URL, method, headers, body), but they're not directly usable inside an application; you need to rewrite them using your language's actual HTTP client.

This converter handles that translation automatically. Paste a cURL command copied from API docs or a browser's Network tab, pick your target language, and get a ready-to-run snippet using requests in Python, fetch in JavaScript, or axios in Node.js. It pairs well with the JSON Formatter for cleaning up the request body before or after conversion.

How to use this cURL→Code calculator

  1. Copy a cURL command from API documentation or your browser's Network tab ("Copy as cURL").
  2. Paste it into the cURL Command field — multi-line commands with trailing backslashes are handled automatically.
  3. Select your Target Language — Python (requests), JavaScript (fetch), or Node.js (axios).
  4. Read the generated code in the result panel.
  5. Copy the code and paste it into your script or application.
  6. Replace any real API keys or tokens with environment variables before committing or sharing the code.

Formula & Methodology

The converter tokenises the cURL command (correctly handling quoted strings and line continuations), then extracts the URL, method, headers, body, and basic auth credentials before generating idiomatic syntax for the chosen language.

Before (cURL):
curl -X POST https://api.example.com/users \\   -H "Content-Type: application/json" \\   -d '{"name": "Asha"}'

After (Python):
python import requests  url = 'https://api.example.com/users' headers = {     'Content-Type': 'application/json', } data = '{"name": "Asha"}'  response = requests.request('POST', url, headers=headers, data=data) print(response.status_code) print(response.text) 

The method defaults to POST whenever a request body is present and no explicit -X flag overrides it, matching cURL's own default behaviour.

Frequently Asked Questions

A cURL to code converter takes a cURL command — the kind you'd copy from a browser's Network tab or an API's documentation — and translates it into working code in a programming language like Python, JavaScript, or Node.js. Instead of manually rewriting the URL, headers, and request body into your language's HTTP client syntax, the converter does it instantly.
Most API documentation includes example cURL commands you can copy directly. You can also get one from your browser's developer tools — open the Network tab, right-click any request, and choose 'Copy as cURL' to grab the exact request your browser made.
The converter parses the URL, HTTP method (from -X or --request), headers (from -H or --header), request body (from -d, --data, or --data-raw), and basic authentication (from -u or --user). These cover the vast majority of API request patterns found in real-world documentation.
cURL itself defaults to GET unless a request body is provided, in which case it automatically switches to POST. This converter follows the same rule — if your command includes a `-d` or `--data` flag without an explicit `-X`, the generated code uses POST to match cURL's actual behaviour.
Yes — cURL commands copied from documentation or a terminal often span multiple lines using a trailing backslash (\) for readability. The converter handles these line continuations automatically, so you can paste the command exactly as copied.
Python output uses the popular `requests` library, JavaScript output uses the browser-native `fetch` API, and Node.js output uses the `axios` library — three of the most common ways developers make HTTP requests in each environment. Pick whichever matches the environment you're working in.
Python's `requests` and Node.js's `axios` are both external packages that need installing (`pip install requests` or `npm install axios`), while the JavaScript `fetch` output works natively in modern browsers and recent Node.js versions with no extra installation.
No — the parsing and code generation happen entirely in your browser using JavaScript. Your cURL command, including any tokens or credentials it contains, is never transmitted or stored anywhere.
Some advanced cURL flags — like file uploads (-F), client certificates, or proxy settings — aren't translated since they require different handling per target language. For the common case of headers, a JSON or form body, and basic auth, the generated code should run with little to no modification.
Yes — if your cURL command includes a real API key, bearer token, or password, the generated code will contain that same credential. Replace it with an environment variable or placeholder before committing the code or sharing it publicly.
