🔌 cURL to Code Converter

What is a cURL to Code Converter?

cURL is the universal command-line tool for transferring data with URLs. Developers, QA engineers, and API designers use cURL to prototype and debug HTTP requests because it is available on virtually every operating system and supports dozens of protocols. However, once you have a working cURL command, translating it into the exact syntax required by your application code can be tedious and error-prone. Different languages have different HTTP libraries, each with their own conventions for setting methods, headers, request bodies, and authentication.

A cURL to code converter automates that translation. You paste the cURL command you copied from a browser's developer tools, an API reference, or a colleague's message, select your target language, and receive clean, idiomatic code you can drop straight into your project. This tool handles the full range of common cURL flags, including custom methods, headers, JSON and form bodies, basic authentication, cookies, user-agent strings, redirect following, SSL verification skipping, compression, and multipart form uploads.

Because the converter runs entirely in your browser, your API keys, tokens, and request payloads never leave your device. There are no network calls, no server logs, and no data retention. It is completely safe to use with production credentials and sensitive endpoints.

How to Use This Tool

1. Paste your cURL command into the input area at the top of the page. You can also click one of the sample buttons to load a pre-built example.
2. Click "Convert" to parse the command and generate output code. If there is a syntax issue, an error message will explain what went wrong.
3. Choose your target language from the tab bar: JavaScript (fetch), JavaScript (axios), Python, PHP, Go, Ruby, Java, or C#.
4. Review the syntax-highlighted output and click "Copy" to copy the generated code to your clipboard.

Key Features

• Eight Target Languages - Generates idiomatic code for JavaScript fetch, JavaScript axios, Python requests, PHP cURL, Go net/http, Ruby net/http, Java HttpURLConnection, and C# HttpClient.
• Comprehensive Flag Parsing - Handles -X, -H, -d, -u, -b, -A, -L, -k, -F, and more. Supports quoted and unquoted arguments, escaped quotes, and backslash line continuations.
• JSON Auto-Detection - Automatically detects JSON request bodies and formats the output code to use language-native JSON serialization where available.
• Syntax Highlighting - Output code is color-coded for keywords, strings, functions, and types so you can read it quickly before copying.
• Sample Commands - Pre-built examples for GET, POST JSON, POST form, authenticated, and multi-header requests help you explore the tool without writing anything from scratch.
• 100% Client-Side - All parsing and code generation happens in your browser. Your API keys and tokens are never sent anywhere.

Frequently Asked Questions

Where do I get a cURL command to paste?

Most browser developer tools let you copy any network request as a cURL command. In Chrome, open DevTools, go to the Network tab, right-click a request, and choose "Copy as cURL." Firefox and Safari offer similar options. Many API documentation pages also provide ready-made cURL examples you can paste directly.

Does this tool support all cURL flags?

This converter covers the most commonly used flags for HTTP requests, including method, headers, data, authentication, cookies, user-agent, follow redirects, insecure mode, compression, and multipart form data. Rarely used flags like --resolve, --proxy, or protocol-specific options are not currently parsed.

Is it safe to paste commands with API keys or tokens?

Yes. This tool runs entirely in your browser. There are no server requests, no analytics on your input, and no data storage. Your credentials stay on your machine and are never transmitted anywhere.

Can I convert commands with multipart form uploads?

Yes. The parser recognizes the -F and --form flags and generates code that uses the appropriate multipart form data API in each language, such as FormData in JavaScript, a files dictionary in Python requests, or multipart writers in Go.

What happens if my cURL command has a syntax error?

The parser validates the input and displays a clear error message if it cannot find a URL or encounters an unrecognized structure. Common issues include missing the URL entirely, unmatched quotes, or using flags that expect an argument without providing one.
