How the cURL to Code Converter Works

What the Tool Does

The cURL to Code converter transforms cURL commands into executable code snippets for various programming languages using server-side processing. This converter parses cURL commands using advanced Bash parsing capabilities, extracts HTTP methods, URLs, headers, and data payloads, then generates equivalent code in JavaScript (fetch), Python (requests), Node.js (axios), Go, PHP, and Ruby. The tool handles complex cURL features including GET, POST, PUT, DELETE requests, custom headers, JSON payloads, form data, authentication headers, and advanced Bash syntax. The converter provides real-time code generation as you type, making it easy to convert API testing commands into production-ready code.

Common Developer Use Cases

Developers use cURL to Code converters when migrating API testing commands to application code, converting documentation examples into working code, or quickly adapting cURL commands for different programming languages. Many developers find this tool useful when working with REST APIs, integrating third-party services, or converting Postman/Insomnia exported cURL commands into application code. The converter is particularly valuable when working with APIs that provide cURL examples in their documentation, allowing developers to quickly generate code in their preferred language without manual translation.

Supported Languages and Features

The cURL to Code converter supports multiple programming languages: JavaScript (using native fetch API), Python (using requests library), Node.js (using axios library), Go (using net/http package), PHP (using cURL extension), and Ruby (using Net::HTTP). The converter handles HTTP methods (GET, POST, PUT, DELETE, PATCH), custom headers (including Content-Type, Authorization, and custom headers), JSON payloads (automatically formatted for each language), form data (URL-encoded and multipart), authentication (Bearer tokens, API keys, basic auth), and complex Bash syntax including ANSI-C quoted strings and heredocs. The generated code includes proper error handling, response parsing, and follows language-specific best practices.

Server-side Processing

This tool uses server-side processing with the curlconverter library, which leverages tree-sitter-bash for advanced Bash parsing capabilities. Server-side processing ensures accurate parsing of complex cURL commands, handles edge cases reliably, and provides consistent results across all browsers and devices. All processing is stateless - your cURL commands are not stored on the server.
