The cURL converter translates cURL commands into ready-to-run HTTP client code for 40+ languages and frameworks. Paste a curl command, pick a target language, and get equivalent request code with syntax highlighting. It is most useful when an API guide shows a curl example and you need it in Python, Go, or another language without rewriting the headers and body by hand.
A real conversion example
Input — a GET request with an auth header:
curl -X GET "https://api.example.com/users?page=1&limit=10" \
-H "Authorization: Bearer eyJhbGci..."
Python requests output:
import requests
url = "https://api.example.com/users"
params = {"page": "1", "limit": "10"}
headers = {"Authorization": "Bearer eyJhbGci..."}
response = requests.get(url, params=params, headers=headers)
print(response.json())
Node.js fetch output:
fetch("https://api.example.com/users?page=1&limit=10", {
headers: { "Authorization": "Bearer eyJhbGci..." }
}).then(r => r.json()).then(console.log);

How common curl flags map to generated code
| curl flag | What it means | Where it shows up |
|---|---|---|
-X POST | HTTP method | POST call in target language |
-H "Content-Type: ..." | Request header | headers object |
-d '{"key":"val"}' | JSON body | body / data parameter |
-F "[email protected]" | Multipart upload | file read + multipart form |
-u user:pass | Basic auth | Authorization header or auth param |
-b "session=abc" | Cookie | Cookie header |
When conversion fails or produces wrong output
The parser depends on standard curl syntax. The most reliable source is the "Copy as cURL" option from a browser DevTools Network tab — that format is always well-formed.
Common causes of failure:
- Curly quotes (
") instead of straight quotes (") — usually introduced by pasting from a word processor or PDF - Incomplete line continuations: each backslash
\must be the very last character on the line with no trailing space - Non-standard flags or shell substitutions (
$(...), backticks) — the converter parses literal values only
