What is cURL to Code Conversion?
cURL is the universal command-line tool for making HTTP requests. Developers use it to test APIs, debug endpoints, and share request examples in documentation. However, when you need to integrate those same requests into application code, manually translating curl flags to language-specific HTTP libraries is tedious and error-prone. This tool automates that process by parsing your curl command and generating clean, idiomatic code in five popular programming languages: JavaScript (fetch), Python (requests), Go (net/http), PHP (curl), and Node.js (axios).
How to Use This Tool
Select your target programming language using the buttons at the top. Paste your curl command into the input area. The tool parses the command in real time and displays the generated code below. It handles common flags including -X (method), -H (headers), -d (request body), -u (basic authentication), and -b (cookies). JSON request bodies are automatically detected and formatted using the appropriate language-specific JSON methods. Use the "Load sample" button to see an example POST request with headers and a JSON body.
Common Use Cases
- Converting API documentation curl examples into your project language
- Translating browser DevTools "Copy as cURL" output into application code
- Generating boilerplate HTTP client code from Postman or Insomnia curl exports
- Learning how different languages handle HTTP requests by comparing outputs
Why Use a Client-Side Tool?
Your curl commands often contain sensitive data such as API keys, authentication tokens, and internal URLs. This tool processes everything in your browser with no server-side component. Nothing is transmitted, stored, or logged. The tool works offline and generates results instantly. This makes it safe to use with production credentials and private API endpoints.
Frequently Asked Questions
Which curl flags does this tool support?
The parser handles commonly used flags including -X (method), -H (headers), -d/--data/--data-raw (body), -u (basic auth), -b (cookies), -L (follow redirects), -s (silent), -k (insecure), and -v (verbose). Flags without arguments are recognized and handled appropriately.
What programming languages are supported?
The tool generates code in JavaScript (fetch API), Python (requests library), Go (net/http), PHP (curl functions), and Node.js (axios). Each output follows idiomatic conventions for the target language.
Does this tool send my curl commands to a server?
No. All parsing and code generation happens entirely in your browser. Your commands, including API keys and credentials, never leave your device. The tool works fully offline.
