Does it run my request?

No. The tool only parses the curl command and generates code in your browser. Nothing is executed and nothing is sent anywhere.

cURL to Fetch: convert curl commands to JS, Python & Go

Paste any curl command and get clean, idiomatic code for browser fetch, Node, Axios, Python requests / httpx, and Go's net/http. Headers, JSON bodies, form data, basic auth, and cookies are all handled.

cURL input

Options

async / awaitUse async/await over .then() for JS targets. Parse JSON bodyIf the body is JSON, emit native objects instead of a string. Error handlingAdd a basic response.ok / try-catch wrapper.

Example

From a one-liner to typed code

A typical "copy as cURL" command from your browser DevTools becomes idiomatic code in any of the supported targets.

cURL command

curl -X POST https://api.example.com/v1/users \
  -H "Authorization: Bearer abc123" \
  -H "Content-Type: application/json" \
  -d '{"name":"Ada","role":"admin"}'

JS fetch

const response = await fetch('https://api.example.com/v1/users', {
  method: 'POST',
  headers: {
    'Authorization': 'Bearer abc123',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({ name: 'Ada', role: 'admin' })
});
const data = await response.json();

Step by step

How to convert curl to code

Paste the curl command

Multi-line commands with \\ continuations are joined automatically. The default sample uses a JSON POST so you can see the shape of the output.

Pick a target language

Use the tabs above the output: fetch, Node, Axios, requests, httpx, or Go. The code regenerates instantly for the new target.

Tweak the options

Toggle async/await, JSON parsing, or basic error handling depending on your codebase's style.

Copy or download

Paste straight into your editor, or save to request.js / request.py / request.go.

FAQ

Frequently asked questions

Which curl flags are supported?

URL, -X/--request, -H/--header, -d/--data, --data-raw, --data-binary, --data-urlencode, --json, -F/--form, -b/--cookie, -u/--user, --compressed, -L/--location, -k/--insecure, -A/--user-agent, -e/--referer, --max-time. Unknown flags are ignored with a hint.

Does the tool run my request?

No. The tool only parses the command and generates code — nothing is executed and no request leaves your browser.

How are JSON bodies detected?

If --json is used, or if a Content-Type: application/json header is set and the body parses as JSON, the generated code uses native objects (JSON.stringify, json= in Python, etc.).

Multi-line curl with backslashes?

Yes. Line continuations (\\ followed by newline) are joined before tokenising, so pasted commands from documentation work as-is.

Will it convert "copy as cURL (bash)" from Chrome?

Yes — Chrome's "Copy as cURL (bash)" output is the canonical format for this tool. PowerShell's syntax is partially supported; for best results use the bash variant.

About

About cURL and its conversions

cURL is the universal HTTP client. Almost every API doc shows a curl command somewhere, and every browser DevTools panel can copy a request as cURL. That makes it the de-facto interchange format for HTTP requests.

What the generator preserves

Method: inferred from -X, or from the presence of body flags (default POST), or GET.
Headers: emitted in declaration order, including duplicates.
Body: JSON, raw, urlencoded form, multipart form, or binary.
Auth: basic auth (-u user:pass) becomes an Authorization: Basic header.
Cookies: -b becomes a Cookie header.

What it deliberately drops

-v, -s, --progress-bar and other transport-only flags.
--cacert, --cert, --key — these need filesystem context.
