↔️ Curl Converter

Paste a curl request and get deterministic fetch, Node, and Python snippets from the same parser used by the API.

Curl conversion checks
Parses method, URL, headers, body payloads, basic auth placeholders, and unsupported flags. Curl Converter keeps shell quoting and curl-only behaviors visible instead of pretending every flag maps cleanly.
 Runs in your browser
Curl conversion runs locally in your browser. Commands can contain bearer tokens, cookies, or private URLs, so redact secrets before sharing generated snippets.
What this tool does
Curl Converter turns common curl requests into browser fetch, Node fetch, and Python requests snippets.
Why it is useful
It saves developers and agents from re-parsing the same HTTP command while keeping unsupported curl flags explicit.
How it works
The shared core tokenizes shell-like curl input, extracts method, URL, headers, and body data, then emits copyable request code plus typed warnings.
Best input
Use a single curl command with explicit -X, -H, and --data flags. Redact credentials before saving or sharing output.
Agent workflow tip
Copy the JSON summary when asking an agent to debug an API request so it can see parsed method, URL, headers, body presence, and warnings.
Privacy note
Browser use is local; the API route submits the command to Utilito's serverless function for automation.
Important limitation
This is a practical converter, not a full shell or curl emulator. Review redirects, cookies, compressed responses, TLS flags, and auth helpers manually.
Quick answers
Does this execute the request?
No. It converts the command into code and reports parser warnings; it does not call the target URL.
Can it convert every curl flag?
No. It handles common method/header/body cases and surfaces unsupported flags for manual review.
Common Use Cases
Move API examples into docs
Convert a copied curl command into fetch or Python snippets for README and SDK notes.
Debug agent HTTP plans
Give an agent the parsed JSON summary instead of a fragile shell command.
Review secret exposure
Spot bearer tokens and cookies in headers before sharing an API reproduction.
API examples
Call the same deterministic core through Utilito’s compact API router. Send only data you intentionally submit to the server-side endpoint.

Convert a curl command with curl
curl
curl -X POST https://utilito.dev/api/run \
  -H "Content-Type: application/json" \
  -d '{"tool_id":"curl-converter","input":{"input":"curl -X POST https://api.example.com/v1/messages --data hello"}}'
Convert a curl command from JavaScript
javascript
const res = await fetch('https://utilito.dev/api/run', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    tool_id: 'curl-converter',
    input: { input: 'curl -X POST https://api.example.com/v1/messages --data hello' }
  })
});
const data = await res.json();
console.log(data.result.output || data.result.report);
Convert a curl command from Python
python
import requests
payload = {
    "tool_id": "curl-converter",
    "input": {"input": "curl -X POST https://api.example.com/v1/messages --data hello"},
}
result = requests.post("https://utilito.dev/api/run", json=payload).json()["result"]
print(result.get("output") or result.get("report"))
HTTP Developer Workbench workflow
Move between curl conversion, webhook testing, status-code reference, typed HTTP security diagnostics, redirect-chain analysis, status samples, MIME lookups, and user-agent parsing while keeping network behavior explicit.
