How to Convert cURL Commands to Code
Transform terminal commands into programming languages in four steps:
Paste cURL
Copy any cURL command from API documentation or browser network inspector.
Choose Language
Select JS fetch(), Axios, Python Requests, Go net/http, or PHP.
Inspect Generated Code
Review parsed HTTP headers, JSON body serialization, and error handlers.
1-Click Copy
Copy clean ready-to-run code directly into your application codebase.
Key Features & Language Engines
5 Supported Languages
Converts seamlessly to modern JavaScript fetch, Axios, Python Requests, Go, and PHP.
Header & Auth Preservation
Accurately preserves Authorization Bearer tokens, API keys, and custom headers.
JSON Body Serialization
Automatically detects JSON payloads and formats `JSON.stringify` and `json=payload` calls.
100% In-Browser Privacy
Confidential API secrets, private keys, and endpoints never leave your web browser.
Zero-Latency Compilation
Instant parsing on every keystroke without waiting for cloud compile queues.
1-Click Clipboard Copy
Fast 1-click copy with non-blocking toast notifications.
Bridging API Documentation and Production Code with cURL
Almost all REST API documentation (Stripe, OpenAI, GitHub, Twilio) provides code examples in cURL. Translating raw cURL commands into asynchronous JavaScript `fetch()` calls or Python `requests` scripts manually is error-prone, especially when dealing with escaping nested JSON quotes and URL query parameters.
Nextgen Astra cURL Converter delivers instant, flawless code translation across all major HTTP libraries directly in your browser.

Frequently Asked Questions
?How does the online cURL Converter parse terminal commands?
The tool tokenizes command line arguments, extracting HTTP methods (`-X POST`), headers (`-H`), request bodies (`-d`), and URLs to generate clean, native code snippets across 5 languages.
?What programming languages and HTTP libraries are supported?
Supports JavaScript `fetch()`, `axios`, Python `requests`, Go `net/http`, and PHP `curl_exec`.
?Does it automatically format JSON bodies?
Yes! If the request body is valid JSON, it wraps it cleanly in `JSON.stringify(...)` for JavaScript or passes it as `json=payload` in Python.
?Are my private API tokens, authorization keys, or URLs secure?
Yes! 100% of command parsing and code generation execute locally inside your web browser. No requests or API tokens are ever sent to external servers.
?Can I convert multi-line cURL commands with backslashes (\)?
Yes! The parser automatically unescapes line-continuation backslashes and normalized multi-line terminal commands.
