Curl to Fetch Converter
Convert a cURL command into a standard JavaScript `fetch` or `axios` request snippet.
What is the Curl to Fetch Converter?
The cURL to Fetch Converter is a free online tool that turns a cURL command into ready-to-use JavaScript HTTP request code. Paste a command and it generates a fetch() snippet, an async/await version, and an equivalent Axios call.
It parses the request URL, the HTTP method from -X, every -H header, and the request body from -d, --data, or --data-raw. JSON bodies are detected and pretty-printed inside JSON.stringify so the generated code stays readable.
All parsing happens in your browser. No cURL command, header, or token you paste is uploaded, making it safe to convert requests that include authorization headers during development.
How to use the Curl to Fetch Converter
- 1Paste your cURL command into the input box, or load one of the GET, POST JSON, or multiple-headers examples.
- 2Click Convert to JavaScript Fetch, or press Ctrl+Enter, to parse the command.
- 3Read the generated fetch() code, which includes the method, headers object, and body.
- 4Scroll to the async/await version for try/catch error handling and a response.ok status check, or copy the Axios version if you prefer that library.
- 5Use the Copy button to copy the fetch snippet to your clipboard. Press Ctrl+L to reset the input.
What you can use it for
- Converting a request copied from the browser DevTools Network tab using Copy as cURL into application code.
- Translating a cURL example from API documentation into a working fetch() call for a frontend project.
- Migrating shell scripts that use cURL into JavaScript or TypeScript HTTP calls.
- Generating an Axios equivalent of an existing cURL request without rewriting the headers and body by hand.
- Producing a starting async/await snippet with error handling for a new API integration.
Key features
- Generates three outputs from one command: a fetch() snippet, an async/await version, and an Axios call.
- Parses URL, method, repeated -H headers, and request body from -d, --data, or --data-raw.
- Detects JSON request bodies and pretty-prints them inside JSON.stringify.
- Validates that a URL is present and starts with http://, https://, or a leading slash.
Frequently asked questions
How do I convert a cURL command to JavaScript fetch?
Paste the cURL command into the converter and click Convert to JavaScript Fetch. The tool extracts the URL, method, headers, and body, then outputs a fetch() snippet along with async/await and Axios versions you can copy directly.
Does the cURL to Fetch converter handle request headers and bodies?
Yes. It reads every -H header into a headers object and extracts the request body from -d, --data, or --data-raw. JSON bodies are parsed and pretty-printed inside JSON.stringify for readable output.
Is it safe to paste cURL commands with API keys or tokens?
Yes. The conversion runs entirely in your browser and nothing you paste is transmitted to a server. Authorization headers and tokens stay on your machine, though you should still avoid sharing the generated code if it embeds real credentials.
Can it generate Axios code instead of fetch?
Yes. After converting, the tool shows an Axios Version section with an equivalent axios call using the same URL, method, headers, and body, so you can use whichever HTTP client your project relies on.
Why does the converter show a URL error?
The tool requires a recognizable request URL. If no URL is found, or the URL does not start with http://, https://, or a leading slash, it returns an error message instead of generating code. Check that the command begins with curl followed by a valid URL.
Does it support converting cURL copied from browser DevTools?
Yes. You can right-click a request in the Network tab, choose Copy as cURL, and paste it directly. The converter handles multi-line commands with backslash continuations as well as single-line commands.
