How This cURL to Fetch Converter Works
Paste a curl command, pick a target (fetch, axios, Python requests, or Node.js), and this convert curl to fetch tool returns working code instantly. At its simplest it's a paste curl get code tool, no manual translation of flags or headers needed. It tokenizes the command respecting quoted arguments, so headers and request bodies with spaces inside quotes parse correctly, and multi-line commands using a trailing backslash for line continuations are joined and parsed the same as a single-line command. As a curl to javascript converter, it re-checks the output every time you edit either the command or the target, so switching from fetch to axios on the same input is instant.
Supported cURL Flags
As a curl converter online, this curl command converter recognizes the flags used in the overwhelming majority of real-world API requests, most commonly the ones a browser's "Copy as cURL" or an API doc's example command actually produces.
| Flag | Meaning | Maps to |
|---|---|---|
| -X, --request | HTTP method | method / requests.<method>() |
| -H, --header | Request header | headers object |
| -d, --data, --data-raw, --data-binary | Request body | body / data, and implies POST if no method is set |
| -u, --user | Basic auth (user:pass) | Authorization: Basic header, or auth= in Python |
| -k, --insecure | Skip TLS verification | noted in the parsed summary |
| --compressed | Accept compressed responses | Accept-Encoding header (fetch output) |
| -G, --get | Force GET method | method |
Converting to fetch, axios, Python, or Node.js
Each output target has its own conventions this curl to javascript converter follows: the fetch output awaits the response and calls .json() on it separately since fetch doesn't parse the body automatically, the curl to axios output destructures data directly from the response since axios parses JSON for you, the curl to python requests output calls requests.<method>(url, headers=..., data=..., auth=...) matching the requests library's usual style, and the curl to node js output uses the built-in https module with a raw options object rather than a fetch polyfill, since that dependency-free approach works in any Node version without installing anything.
Common Uses
Turning a "Copy as cURL" command copied from a browser's Network tab into working app code, porting an API call exported from Postman or Insomnia into a script, and converting an example command from a third-party API's documentation into the language you're actually using are the most common uses for this curl to fetch converter. Teaching or onboarding developers who are comfortable reading curl syntax but need it translated into JavaScript or Python, and quickly testing an endpoint found in a support ticket or bug report, are common secondary uses.
What This Tool Doesn't Do
This tool doesn't parse multipart form uploads (-F, --form) or cookie flags (-b, --cookie), and proxy, retry, and output-redirection flags are ignored rather than converted. Most importantly, curl commands often carry real credentials in an Authorization header or a -u flag, and conversion here runs through our server rather than entirely in your browser, so avoid pasting a curl command with live secrets, or replace them with placeholder values first and fill in the real ones in your own code afterward.
