cURL to Code Converter — Free Online

Paste a cURL command and instantly generate working code for JavaScript fetch, axios, Python requests, C# HttpClient, Go, Java, PHP, Ruby, Kotlin, and more. Runs entirely in your browser.

cURL Input — paste your command

🔒 Runs entirely in your browser. Your cURL command never leaves your device.

Why Convert cURL to Code?

cURL is the universal language of HTTP requests — every API's documentation includes a cURL example, and browser developer tools can copy any request as cURL. But when you need to integrate that request into your application, you need it in your programming language. This tool bridges that gap instantly.

Supported Output Languages

Language / LibraryUse Case
JavaScript fetchBrowser and modern Node.js HTTP requests
JavaScript axiosPromise-based HTTP client with interceptors
Node.js undiciHigh-performance HTTP/1.1 client for Node
Python requestsThe most popular Python HTTP library
C# HttpClient.NET HTTP requests with async/await
Go net/httpGo standard library HTTP client
Java HttpClientJava 11+ built-in HTTP client
PHP cURLPHP's native cURL extension
Ruby net/httpRuby standard library HTTP
Kotlin OkHttpSquare's popular HTTP client for JVM

How the Parser Works

The parser tokenizes your cURL command, handling single-line and multi-line (backslash-continuation) inputs, single and double quotes, and all common flags including -X, -H, -d, --data-raw, --data-binary, -u, -L, -k, --compressed, and -b. It produces a canonical Request Model that every code renderer depends on — giving you consistent, correct output across all languages.

Secret Masking

By default, the tool masks likely secrets in output: Authorization header values, bearer tokens, API keys in query strings, and long random-looking strings (20+ characters with mixed character types). Toggle masking off when you need the real values for copy-paste into your code.

🔒 Safe for Production API Keys and Tokens

This converter runs entirely in your browser's JavaScript engine. Your cURL command — including any API keys, bearer tokens, passwords, or credentials — is parsed locally in memory and never transmitted to any server.

You can verify this by opening your browser's developer tools (F12 → Network tab) and observing that no request contains your input data.

What This Tool Does

Converts cURL commands into working, production-ready code for Python requests, JavaScript fetch, axios, C# HttpClient, Go net/http, Java HttpClient, PHP, Ruby, and more — processed locally in your browser.

Who This Is For

Example: Input: A cURL command with headers, POST body, and Bearer token authentication → Output: Ready-to-run Python requests.post(), JavaScript fetch(), or C# HttpClient.PostAsync() code with all headers and body correctly mapped

Frequently Asked Questions

Does this tool handle multi-line cURL commands?
Yes — the parser handles backslash line continuations, so you can paste multi-line cURL commands exactly as they appear in terminal output or API documentation.
Are my API keys and tokens safe?
Yes. All processing runs in your browser — your cURL command never leaves your device. The optional secret masking feature replaces likely credentials in the output code with placeholder strings.
Why does the generated code look different from what I expected?
The converter normalizes the request to idiomatic code for each language. For example, headers are passed as a dictionary in Python, and the request body is parsed to a typed object in C#. This produces cleaner code than a literal translation of the cURL flags.
What cURL flags are supported?
All common flags are supported: -X (method), -H (header), -d / --data-raw / --data-binary (body), -u (basic auth), -L (follow redirects), -k (skip SSL), -b (cookie), and --compressed. Uncommon flags are noted in the output as comments.
Can I convert from browser DevTools?
Yes — in Chrome or Firefox DevTools, right-click any network request and choose "Copy as cURL". Paste the result directly into this converter to generate code in any supported language.
