Curl to Fetch Converter
Guide & Explanations
Curl to Fetch Converter — Transform your API requests instantly
The Curl to Fetch Converter is an essential tool for web developers who want to quickly integrate API documentation examples into their JavaScript code. It translates Curl commands (often used in technical documentation) into code using the native fetch API of modern browsers.
Why use our converter?
Most API documentations (Stripe, Twilio, OpenAI, etc.) provide examples in Curl format. Manually copying and rewriting them in JavaScript is error-prone and time-consuming. Our tool automates this process by intelligently handling headers, HTTP methods (GET, POST, PUT, DELETE), and request bodies.
Key Features
- Full Parameter Support: Handles common Curl flags such as
-X,-H,-d,--data-raw, and even Basic Auth (-u). - Two Generation Styles: Choose between the modern Async/Await format (recommended) or the classic promise-based .then() format.
- Smart JSON Handling: If your request contains JSON, the tool automatically suggests using
JSON.stringify()for clean integration. - Validation and Correction: Detects malformed Curl commands and cleans up superfluous line break characters.
- Premium Interface: A clear workspace with simulated syntax highlighting, quick copy button, and demo examples.
Security and Privacy
Like all Dolf.in tools, the Curl to Fetch converter is 100% serverless. Your Curl commands, which may contain API Keys or sensitive data, never leave your browser. The conversion is performed locally on your machine.
