cURL to Code
API docs love to ship a cURL one-liner. Paste it here and get the equivalent in fetch, axios or Python requests, with headers, JSON bodies and basic auth translated for you. It runs entirely in your browser.
const res = await fetch("https://api.example.com/v1/orders", {
method: "POST",
headers: {
"Authorization": "Bearer sk_test_123",
"Content-Type": "application/json",
},
body: JSON.stringify({"item":"widget","qty":2}),
});
const data = await res.json();Wiring a third-party API into your stack and the docs only ship cURL? I build the typed, retried, observable client around it so it's production-ready, not just working.
Integrate it properly: book a callHandles the flags people actually paste: -X, -H, -d and friends, --json, -u, -b, -A. Uncommon flags are ignored rather than breaking the parse. A JSON body under a JSON content-type is emitted as a real object, not a stringified blob.

From copy-paste to a real client
Translating cURL by hand is where silent bugs sneak in: a header dropped, a JSON body left as a string, auth encoded wrong. Getting a faithful starting point in your language removes that whole class of mistake and saves the trip to the docs for each option's exact name.
This gets you a working call. Production wants more around it: timeouts, retries with backoff, typed responses, and errors you can actually act on. That layer is the difference between a script and an integration.

Questions & answers
- What does the cURL to Code Converter output?
- It parses a cURL command and generates the equivalent code as JavaScript fetch, JavaScript axios, or Python requests. It handles the method, headers, request body, basic auth, user-agent, referer and cookies.
- Is my cURL command sent anywhere?
- No. The command is parsed and converted entirely in your browser with no network call, so any tokens or credentials in it never leave the page.
- Why is my JSON body shown as a string instead of an object?
- It only emits the body as a real object when the Content-Type header is application/json and the body is valid JSON. Without that header, or with invalid JSON, it keeps the body as a string literal to stay faithful to your command.
- Which cURL flags does it support?
- It reads the method, headers, the data family including raw and urlencoded bodies, the json flag, basic auth, user-agent, referer and cookies. Flags that do not change the request, like follow-redirects or silent, are skipped rather than treated as errors.
- How is basic auth handled?
- A user and password pair is base64 encoded into an Authorization: Basic header in the generated code, so the request carries the credentials the same way cURL would send them.
