cURL to Fetch Converter
Parse raw cURL shell terminal commands instantly into clean, executable JavaScript Fetch, Axios, or Node.js code snippets.
Parsed Request Blueprint
In-Browser cURL to Modern Fetch API Code Conversion
The cURL to Fetch Converter translates command-line cURL commands into clean, idiomatic JavaScript and TypeScript code using the standard Fetch API. Developers frequently copy cURL examples from API documentation or browser network tabs and need to translate them into frontend application code.
This utility parses complex cURL command flags, including HTTP methods (-X, --request), headers (-H, --header), raw body payloads (-d, --data, --data-raw), and basic authentication credentials (-u, --user). All arguments are mapped directly to Fetch options objects.
The output code includes proper async/await error handling, TypeScript interface definitions, and JSON response parsing. Conversion executes entirely within your browser, ensuring API keys and authorization tokens are never sent to external servers.
Core Tool Capabilities
- Comprehensive cURL Flag Parsing: Interprets standard flags including -X, -H, -d, --data-urlencode, -b, -u, and --compressed.
- Automated JSON Body Formatting: Detects JSON payload strings and wraps them in JSON.stringify() with clean indentation formatting.
- TypeScript Interface Generation: Produces modern TypeScript syntax with typed fetch calls and response parsing boilerplate.
- Secure Client-Side Translation: Protects private API bearer tokens and basic auth credentials by processing everything inside your browser.

Technical Specifications and Platform Limits
Outputs standard global fetch API code
Generates clean async/await functions

Step-by-Step Workflow
Copy cURL Command
Copy a cURL request from API documentation or right-click a network request in your browser dev tools and select Copy as cURL.
Paste into Converter
Paste the terminal command into the input editor for immediate lexical analysis.
Select Output Style
Toggle between standard JavaScript async/await, modern TypeScript, or promise-chaining syntax.
Copy Converted Code
Copy the ready-to-run fetch() function directly into your application codebase.
Practical Real-World Use Cases
Frontend API Integration
Web developers converting third-party REST API documentation examples into React, Vue, or Svelte data hooks.
Network Request Debugging
Engineers copying failing requests from browser Network tabs as cURL to reproduce them in frontend unit tests.
Node.js Microservices
Backend engineers converting external HTTP webhook calls into native Node.js fetch routines without external dependencies.
API Documentation Writing
Technical writers generating multi-language code snippets from base terminal cURL references.
Frequently Asked Questions
- Does this tool support POST, PUT, DELETE, and PATCH methods?
- Yes. The converter extracts the HTTP method from -X or --request flags and assigns it to the fetch options method.
- How are Bearer authorization tokens handled?
- Authorization headers (-H "Authorization: Bearer ...") are parsed and preserved directly inside the headers object.
- Can the tool parse multi-line cURL commands with backslashes?
- Yes. The lexer normalizes terminal continuation backslashes and line breaks before parsing arguments.
- Are my private API keys or tokens uploaded to your server?
- No. All conversion logic runs locally inside your web browser with zero network requests.
- Does the output support modern async/await syntax?
- Yes. Output code is generated as clean, modern async functions with structured try/catch blocks.
