cURL to Fetch Converter
Convert curl commands to JavaScript fetch or axios.
async function main() {
const response = await fetch('value"}', {
method: 'POST',
headers: {
'Content-Type': ''
},
body: "{\"key\":"
});
const data = await response.json();
console.log(data);
}
main();About this tool
cURL is a command-line tool widely used by developers to make HTTP requests, while modern web applications use the Fetch API or axios library. The cURL to Fetch Converter translates cURL commands into JavaScript code that performs the same HTTP request in a browser or Node.js environment. This eliminates the need to manually rewrite each parameter, header, and body when moving from server-side curl commands to client-side JavaScript.
To use the converter, paste your cURL command into the input field and select your target format—JavaScript Fetch API or axios. The tool automatically parses headers, request bodies, authentication tokens, and query parameters, then outputs clean, ready-to-use code. Common use cases include converting API documentation examples from cURL format to JavaScript, translating curl snippets from API testing tools like Postman or Insomnia into frontend code, and quickly prototyping HTTP requests without rewriting syntax.
Developers benefit most when working with REST APIs, webhooks, or microservices that provide cURL examples in their documentation. The converter handles complex scenarios such as file uploads, custom headers, and different HTTP methods—making it especially useful for frontend engineers who need to implement backend API calls without deep familiarity with cURL syntax. Note that highly specialized curl options (like proxy tunneling or client certificates) may require manual adjustment in the generated code.
