How to cURL to Code Converter Online

  1. Paste your cURL command into the input area on the left. Multi-line curl commands with backslash continuations are supported.

  2. Choose your target language from the language selector in the bottom bar — JavaScript fetch, Axios, Python requests, Go, PHP, Ruby, Java, C#, Rust, Swift, or Kotlin.

  3. Click Convert or press ⌘↵ to generate idiomatic code instantly.

  4. Toggle the Request Inspector (⌘⇧I) to verify the parsed URL, method, headers, body, and authentication.

  5. Copy the generated code with ⌘⇧C, download it as a file, or share your cURL command via a compressed URL.

cURL to Code Converter Features

  • 14 language targets: JavaScript fetch, Axios, Node.js http, Python requests, Python http.client, Go net/http, PHP cURL, Ruby Net::HTTP, Java HttpClient, C# HttpClient, Rust reqwest, Swift URLSession, Kotlin OkHttp, and PowerShell.

  • Complete cURL flag support: -X, -H, -d, --data-raw, --data-binary, --data-urlencode, -F (multipart), -u (basic auth), -b (cookies), -L (follow redirects), -k (insecure), --compressed, -o, --connect-timeout, -m, --proxy.

  • Smart body type detection: automatically identifies JSON body, form-urlencoded, and multipart data from the cURL flags and content.

  • Request inspector: visual breakdown of the parsed request showing URL, method, header count, body type, auth type, and cookies.

  • Multipart form support: handles -F file uploads and form fields with correct multipart/form-data encoding per language.

  • Basic authentication: parses -u user:password and generates language-specific auth code (Authorization header, auth parameter, etc.).

  • Line continuation support: correctly parses multi-line cURL commands using backslash line continuations.

  • Auto-convert mode: regenerates code as you type for instant feedback.

  • Shareable URLs: gzip-compresses your cURL command into a URL parameter for sharing with teammates.

  • Works entirely in your browser — no cURL commands are ever sent to any server. Your API keys and tokens stay private.

  • Keyboard shortcuts: ⌘↵ to convert, ⌘⇧C to copy, ⌘⇧K to clear, ⌘⇧I to inspect.

Supported SQL Dialects

The cURL to Code Converter supports 12 SQL dialects. Select the right dialect for accurate formatting and keyword recognition.

JavaScript — fetch()
Modern browser-native HTTP API using async/await. Works in all modern browsers and Node.js 18+.
JavaScript — Axios
Popular promise-based HTTP client for browser and Node.js. Generates config-object style with response interceptors.
Node.js — http/https
Built-in Node.js modules with zero external dependencies. Uses the native request/response stream API.
Python — requests
The de facto standard Python HTTP library. Generates idiomatic code with session objects, auth tuples, and JSON body detection.
Python — http.client
Python standard library HTTP client. Zero external dependencies, useful in restricted environments.
Go — net/http
Go standard library HTTP client. Generates idiomatic Go with proper error handling and defer body close.
PHP — cURL
PHP cURL extension using curl_init(), curl_setopt(), curl_exec(). The most common PHP HTTP pattern.
Ruby — Net::HTTP
Ruby standard library HTTP client. Generates URI-based requests with proper SSL configuration.
Java — HttpClient
Java 11+ java.net.http.HttpClient. Modern, non-blocking API replacing the legacy HttpURLConnection.
C# — HttpClient
.NET HttpClient with async/await. Generates idiomatic C# with StringContent, FormUrlEncodedContent, or MultipartFormDataContent.
Rust — reqwest
Most popular Rust HTTP client. Generates async code with tokio runtime and proper error handling via Result.
Swift — URLSession
Apple Foundation framework URLSession. Generates async/await code compatible with iOS 15+ and macOS 12+.

Frequently Asked Questions

Is this cURL converter free?
Yes, DevFlow cURL to Code Converter is completely free with no usage limits. All parsing and code generation runs directly in your browser — no account required.
Is my cURL command safe?
All parsing happens entirely in your browser using pure JavaScript. No cURL commands, API keys, tokens, or any data is ever transmitted to a server. Your sensitive credentials stay completely private on your machine.
What cURL flags are supported?
The converter supports 22 commonly used cURL flags including -X (method), -H (headers), -d (body data), --data-raw, --data-binary, --data-urlencode, -F (multipart form), -u (basic auth), -b (cookies), -L (follow redirects), -k (insecure), --compressed, -o (output file), --connect-timeout, -m (max time), and --proxy.
How do I convert a cURL command from Chrome DevTools?
In Chrome DevTools, right-click a network request → Copy → Copy as cURL. Paste the copied command directly into this tool and select your target language. The converter handles the exact format Chrome exports, including all headers and cookies.
Does it handle multipart file uploads?
Yes. cURL commands using -F (or --form) flags for file uploads and form fields are parsed correctly. The generated code includes language-specific multipart/form-data handling — FormData in JavaScript, files parameter in Python requests, multipart/form-data in Go, etc.
What if my cURL command has line continuations?
Multi-line cURL commands using backslash (\) line continuations are fully supported. The parser joins continued lines before processing, so you can paste commands copied from documentation or scripts directly.
Can I convert cURL commands exported from Postman?
Yes. Postman's 'Copy as cURL' export format is fully compatible. Paste the exported command and convert to any language. This is a faster workflow than using Postman's built-in code generation because all processing happens instantly in your browser.
Does the generated code handle authentication?
Yes. Basic authentication via the -u flag is converted to language-specific auth patterns: Authorization header in fetch, auth parameter in Python requests, SetBasicAuth in Go, etc. Bearer tokens and custom Authorization headers set with -H are preserved in all generated code.
Does it work offline?
Yes. All parsing and code generation logic is bundled with the page as pure JavaScript. Once the page has loaded, the cURL to Code Converter works without an internet connection.
