Curl to Code Converter
Paste a curl command to instantly generate equivalent code in Python, JavaScript, PHP, Go, Ruby, and more.
About This Tool
The Curl to Code Converter is a free, browser-based tool that transforms curl commands into production-ready code in six popular programming languages: Python (requests), JavaScript (fetch), JavaScript (axios), PHP (cURL extension), Go (net/http), and Ruby (Net::HTTP). Developers frequently encounter curl commands in API documentation, Stack Overflow answers, and DevTools network exports, and translating them manually into application code is tedious and error-prone.
This tool handles the full range of commonly used curl flags,
including -X (HTTP method), -H (headers),
-d / --data / --data-raw
(request body), --data-urlencode (URL-encoded body
parameters), -u (basic authentication),
-b (cookies), -L (follow redirects), and
-k (skip TLS certificate verification). Multi-line
curl commands using backslash continuation are fully supported.
All processing happens entirely in your browser. No data is sent to any server, making it safe to convert curl commands that contain API keys, authentication tokens, or other sensitive information. The parser is implemented from scratch in TypeScript with no external dependencies, keeping the tool fast and lightweight.
Common use cases include converting API examples from documentation into your language of choice, migrating shell scripts to application code, debugging HTTP requests by inspecting parsed components (method, URL, headers, body), and learning how different languages structure HTTP client calls. The parsed request details panel shows exactly how the tool interprets your curl command, so you can verify correctness before copying the generated code.
How to Use
- Paste your curl command into the Curl Command input panel on the left. Multi-line commands with backslash continuation are supported.
- Select your target language using the tabs above the panels: Python, JS Fetch, JS Axios, PHP, Go, or Ruby.
- The generated code appears instantly in the right panel. Review the Parsed Request Details section below the panels to verify the method, URL, headers, and body were extracted correctly.
- Click Copy to copy the generated code to your clipboard, or use the keyboard shortcut Ctrl+Shift+C.
- Click Sample to load an example curl command demonstrating POST with JSON body and authorization header.
- Click Clear to reset both panels and start over.

FAQ
Is my data safe when using this tool?
Yes. All parsing and code generation runs entirely in your browser using client-side JavaScript. No data is ever sent to a server. This makes the tool safe for curl commands that contain API keys, tokens, passwords, or other sensitive values.
Which curl flags are supported?
The parser supports -X (method), -H (headers), -d / --data / --data-raw (body), --data-urlencode (URL-encoded parameters), -u (basic auth), -b (cookies), -L (follow redirects), and -k (insecure / skip TLS). Common flags like -s (silent) and -v (verbose) are recognized and silently ignored since they do not affect the request itself.
What languages are supported?
The tool generates code for six targets: Python (using the requests library), JavaScript with the native fetch API, JavaScript with axios, PHP (using the cURL extension), Go (using net/http), and Ruby (using Net::HTTP).
Can I paste multi-line curl commands?
Yes. The parser handles backslash-newline continuation, which is the standard way to split long curl commands across multiple lines in a terminal. Simply paste the command as-is and it will be parsed correctly.
How does the tool handle authentication?
When a -u user:password flag is detected, the generated code uses the idiomatic authentication mechanism for each language. For example, Python uses the auth= parameter, Go uses req.SetBasicAuth(), and axios uses the auth config option. The raw password is included in the output, so treat generated code with the same care as the original curl command.
What if my curl command is not recognized?
If the parser cannot find a valid URL in the command, an error message is displayed. Make sure your input starts with curl (though the keyword itself is optional) and includes a valid URL. Unsupported or unrecognized flags are silently skipped, so the rest of the command will still be parsed.
Does the tool use any external libraries?
No. The curl parser and all code generators are implemented from scratch in TypeScript. No external packages are used for parsing, which keeps the tool fast, lightweight, and free of supply chain concerns.
