About this tool

Copy as cURL is the fastest way to capture a request from your browser devtools, but it is not code you can ship. This converter tokenizes the command exactly like a shell would — respecting quotes, escapes and line continuations — then rebuilds it as idiomatic Python requests, JavaScript fetch or Go net/http. Everything runs locally, so tokens in your Authorization header never leave the page.

How to convert cURL to Python

In Chrome or Firefox devtools, right-click a request in the Network tab and choose Copy → Copy as cURL. Paste it here and pick Python: you get a requests call with a headers dict and, when the content type is JSON, a parsed payload passed via json= so the body is re-encoded correctly.

Which cURL flags are supported

-X/--request, -H/--header, -d/--data (plus --data-raw and --data-binary), -u/--user for basic auth and --url are all parsed. Transport-only flags such as -L, -k, -s and --compressed are ignored because they have no direct equivalent in the generated client code.

Method and body inference

If no explicit method is given, the converter follows cURL's own rule: a request with a body becomes POST, everything else stays GET. JSON bodies are detected from the Content-Type header and converted to native structures — Python dicts with True/False/None, and a JSON string body for fetch and Go.

Best practices

  • Work from a real payload, not a hand-typed sample — encoding bugs hide in whitespace and Unicode.
  • Keep the transformation reproducible: script it in CI once you have confirmed the output here.
  • Never paste live credentials, customer records or production tokens into any web tool you have not audited.
  • Version the inputs and outputs you rely on so a teammate can reproduce the same result later.

Why cURL to Code Converter matters

Small integration details — an encoding, a claim, a header — are where most API bugs actually live, and they are expensive to find in production logs.

Getting them right in seconds keeps debugging sessions short and prevents malformed data from reaching downstream systems.
