What is a Curl to Code converter?
A Curl to Code converter is a tool that transforms curl CLI commands into equivalent source code in various programming languages. Instead of manually translating curl flags like -X, -H, and -d into library-specific API calls, this tool automatically parses your curl command and generates clean, ready-to-use code. It supports over 13 language and library combinations, making it easy to integrate API calls into any project.
How do I use this converter?
Simply paste your curl command into the input area on the left side. The tool automatically detects the HTTP method, headers, request body, and other options from your command. Then select your target programming language from the dropdown menu on the right side. The generated code appears instantly and can be copied to your clipboard with one click. You can also edit the curl command and see the output update in real time.
Is my data safe?
Yes, completely. This tool runs 100% in your browser with zero server communication. Your curl commands, which may contain API keys, authentication tokens, or sensitive URLs, are never transmitted anywhere. All parsing and code generation happens locally on your device using client-side JavaScript. The tool works fully offline after the initial page load.
Which curl options are supported?
The converter supports the most commonly used curl flags including -X/--request (HTTP method), -H/--header (custom headers), -d/--data (request body), -u/--user (basic authentication), -A/--user-agent, -b/--cookie, -L/--location (follow redirects), -k/--insecure (skip TLS verification), -F/--form (multipart form data), and --data-urlencode. Multi-line commands using backslash continuation are also handled correctly.
What programming languages are supported?
The tool supports over 13 language and library combinations. These include JavaScript (fetch, axios, jQuery), Python (requests, http.client), Go (net/http), PHP (cURL, Guzzle), Ruby (net/http), Java (HttpClient, OkHttp), C# (HttpClient), Rust (reqwest), and Swift (URLSession). Each generator produces idiomatic code following the conventions of that specific language and library.
Why does the generated code look different from what I expected?
The converter applies several intelligent transformations to produce clean, idiomatic code. It auto-detects the HTTP method based on flags (e.g., -d implies POST if no -X is set), merges duplicate headers, and follows the conventions of each target library. For example, Python requests will use the json parameter instead of data when the Content-Type is application/json. These optimizations ensure the generated code follows best practices for each language.
How do I copy a curl command from browser DevTools?
In Chrome, open DevTools (F12), go to the Network tab, right-click any request, and select 'Copy > Copy as cURL'. In Firefox, open the Network Monitor, right-click a request, and choose 'Copy > Copy as cURL'. In Safari, enable the Develop menu in preferences, open Web Inspector, go to the Network tab, right-click a request, and select 'Copy as cURL'. The copied command can be pasted directly into this tool.
Code Examples
// Curl to JavaScript fetch converter
// Parse curl command and generate fetch code
function parseCurl(command) {
const normalized = command.replace(/\\\s*\n/g, ' ').trim();
const stripped = normalized.replace(/^curl\s+/, '');
// Tokenize and parse flags
const result = { url: '', method: 'GET', headers: {}, data: null };
// ... parse -X, -H, -d, -u flags
return result;
}
function toFetch(parsed) {
const opts = {};
if (parsed.method !== 'GET') opts.method = parsed.method;
if (Object.keys(parsed.headers).length) opts.headers = parsed.headers;
if (parsed.data) opts.body = parsed.data;
return `await fetch('${parsed.url}', ${JSON.stringify(opts, null, 2)})`;
}
const curl = 'curl -X POST -H "Content-Type: application/json" -d \'{"key":"value"}\' https://api.example.com';
console.log(toFetch(parseCurl(curl)));
