cURL is the universal language of HTTP requests. API documentation, Stack Overflow answers, and debugging guides all share examples as cURL commands because they are concise, unambiguous, and runnable in any terminal. But when you need to integrate an API call into your application, translating a cURL command into idiomatic application code is a manual, repetitive task.
Converting a cURL command to a JavaScript `fetch` call or a Python `requests` call requires understanding which cURL flags map to which code constructs — `-H` becomes request headers, `-d` becomes the request body, `--user` becomes a Basic Auth header, and so on. Miss one flag and your request may fail silently or send incorrect data.
This cURL-to-code converter automates the translation. Paste any cURL command — however complex — and get back clean, ready-to-use code in your language of choice. It handles headers, request bodies, authentication, query parameters, and common cURL flags automatically.
What Is cURL and Why Convert It?
cURL (Client for URLs) is a command-line tool for making HTTP requests. It supports virtually every HTTP feature: methods, headers, request bodies, authentication, cookies, redirects, and more. Because it's available on every platform and requires no setup, it's the de-facto way to share and test HTTP requests.
API providers publish their quickstart examples as cURL commands. Developers copy them from browser DevTools as cURL (via the 'Copy as cURL' option). CI pipelines use cURL to call webhooks. In all these cases, the starting point is a cURL command that needs to become application code.
Manually converting cURL to code is tedious and error-prone. This tool reads the cURL command, parses every flag, and generates syntactically correct, readable code — saving time and preventing subtle bugs introduced by manual translation.
How to Use This Tool
Convert any cURL command to application code in seconds.
- 1
Copy your cURL command
Get a cURL command from API documentation, browser DevTools ('Copy as cURL'), a curl command you wrote yourself, or any other source.
- 2
Paste into the input field
Paste the full cURL command into the input area. Multi-line commands with backslash continuations are supported.
- 3
Select a target language
Choose the output language: JavaScript (fetch), JavaScript (axios), Python (requests), Node.js (https module), PHP (cURL), Go (net/http), or others.
- 4
Click Convert
The tool parses the cURL flags and generates equivalent code in the selected language, preserving all headers, method, body, and authentication.
- 5
Copy and use the code
Copy the generated code snippet and paste it directly into your project. Review variable names and adjust as needed for your codebase.
Common Use Cases
cURL conversion is useful whenever you need to move from a command-line HTTP request to application code.
- Integrating third-party APIs — converting the cURL examples from API docs into Python or JavaScript for use in your backend.
- Reproducing browser requests — using 'Copy as cURL' from browser DevTools and converting to code to automate a request in a script.
- Migrating scripts — converting shell scripts that use curl into language-native HTTP client calls for a new application.
- Learning HTTP — reading the generated code to understand exactly what a cURL command does, broken down into clear language constructs.
- Rapid prototyping — quickly going from a working cURL test call to runnable application code without writing boilerplate.
Tips and Best Practices
Get the most out of cURL conversion with these tips.
- Use 'Copy as cURL' from browser DevTools (Network tab > right-click a request) to get a complete, accurate cURL command including all cookies and headers.
- Review the generated code for hardcoded credentials — strip out any Authorization headers or API keys before committing to version control.
- Check that the Content-Type header is included in the converted code if the original cURL command sends a request body.
- For complex cURL commands with many flags, verify the output against the original to ensure no flags were misinterpreted.
- Use the generated code as a starting point — rename variables, add error handling, and restructure to match your project's coding style.
Frequently Asked Questions
Which cURL flags does the converter support?
The converter handles the most common flags: `-X` (method), `-H` (headers), `-d` / `--data` / `--data-raw` (body), `--user` (Basic Auth), `-b` (cookies), `-L` (follow redirects), and more. Rare or OS-specific flags may not be converted.
Can I convert multi-line cURL commands with backslash continuations?
Yes. The tool parses cURL commands that span multiple lines using `\` as a line continuation character, which is the standard format produced by browser DevTools and most documentation.
Does the converted code include error handling?
The generated code includes basic structure appropriate to the target language, such as promise chains for JavaScript or try/except for Python. You should add production-grade error handling, retries, and logging to suit your application's needs.
Is the generated JavaScript code using fetch or axios?
You can choose. The tool offers both the native Fetch API and the popular axios library as JavaScript output options. Select the one that matches the libraries already used in your project.
Will the converter include my API keys from the cURL command?
Yes — if your cURL command includes an Authorization header or a query parameter with a key, the generated code will include it. Always replace hardcoded credentials with environment variables before using the code in production.
Can I convert the output back to cURL?
This tool converts in one direction: cURL to code. For the reverse — generating a cURL command from code — use the browser DevTools 'Copy as cURL' feature or look for a code-to-cURL tool.
