cURL to Fetch Converter
cURL commands from API docs need to become JavaScript fetch calls. Paste your command here, pick async/await or the .then chain style, and copy clean fetch code with the method, headers, body and auth already translated.
Multi-line cURL (with backslashes) also works.
JavaScript fetch code
How to use
- Paste your cURL command in the box above.
- Choose a code style (async/await or .then chain) and press Convert.
- Copy the ready fetch code and use it in your project.
Tips
- Check that the converter captured every -H header; long commands sometimes wrap lines.
- Secrets in the original cURL stay in the generated code - replace tokens with variables.
- Test the fetch in the browser console before pasting it into your project.
- Some cURL flags like --compressed have fetch equivalents you may need to add by hand.
Supported: -X/--request, -H/--header, -d/--data (-raw, --data-binary), -u/--user (basic auth), --compressed, -k/--insecure, -A/--user-agent, -b/--cookie. The -o flag is ignored. Very complex flags (like form upload) cannot be fully converted.
