⚡cURL to Fetch & Axios Converter Documentation & Guide

Web & Developer
Convert cURL shell commands into clean, idiomatic JavaScript Fetch API, Axios, Python Requests, and Node.js HTTP request code. Automatically parses HTTP methods, headers, authentication tokens, query parameters, and JSON payloads.

📋How to Convert cURL to JavaScript & Python

  1. 1. Paste cURL Command: Copy any cURL command from your terminal, API documentation, or browser DevTools Network tab and paste it into the editor.
  2. 2. Choose Target Client: Select between JavaScript Fetch (async/await or .then), Axios, Python 3 Requests, or Node.js native https.
  3. 3. Configure Error Handling: Toggle between full try/catch error handling blocks or minimal lightweight call snippets.
  4. 4. Convert & Copy Code: Click ⚡ Convert cURL Command to inspect parsed request metadata and copy the ready-to-run code snippet.

⚙️Shell Tokenization & HTTP Grammar Parsing

Command-line syntax parser splits shell strings and reconstructs high-level HTTP client invocations:

• POSIX Shell Tokenizer: Safely handles single and double quote boundaries, escaped characters, and multi-line backslash (`\`) command continuations.
• Header & Auth Deconstruction: Normalizes `-H` / `--header` flags into structured dictionaries and extracts Basic Auth credentials from `-u` / `--user`.
• Payload Formatting: Automatically parses `-d` / `--data` JSON bodies, formatting payloads with clean indentation or stringified representations.
• Cross-Language Code Synthesis: Outputs clean idiomatic code matching the conventions of ES6+ Fetch, Axios, Python Requests, and Node.js.

Compatible with modern frontend frameworks (React, Vue, Svelte, Next.js) and backend runtimes (Node.js, Deno, Bun, Python 3).

💡Practical Use Cases

  • API Integration: Transform third-party cURL examples directly into production-ready frontend or backend client code.
  • DevTools Export Re-use: Copy network requests from Chrome/Firefox DevTools as cURL and convert them to integration tests.
  • Multi-Language SDK Porting: Quickly rewrite shell scripts or test invocations into maintainable Python and Node.js scripts.
100% Client-Side Privacy Guarantee:All cURL parsing and code generation run completely locally inside your browser sandbox. API keys, authorization tokens, and confidential request bodies are never transmitted over the network.
