Free online tool to convert cURL commands to HTTP request code in JavaScript (Fetch/Axios), Python (requests), Java, Go, and more. One-click conversion for quick integration.
TL;DR: Convert cURL commands to HTTP request code in multiple languages
For local tools, open DevTools → Network and search your input — it should not appear in requests.

Usage Guide
Translate a curl command into runnable request code for JavaScript fetch, Axios, Python requests, Java HttpClient, or Go net/http — or tidy the curl itself. Paste what DevTools or an API doc handed you; parsing stays in your tab so the command text is not sent to a remote converter. Treat the output as a draft you will wire into project configuration, not a finished SDK with retries, pagination helpers, or typed models.
1. Convert one command
Parse errors usually mean unbalanced quotes, a truncated -d body, or shell noise mixed into the paste. Fix the curl until the summary strip (method, URL, header count) looks right, then worry about language idioms. Multi-line JSON bodies must keep their quotes intact — if DevTools wrapped them oddly, repair the curl before converting.
- Paste the full curl, including quotes and backslash line continuations. Use Load example if you want a known-good shape first.
- Pick the target language: js-fetch, js-axios, python, java, go, or curl. The output updates when the parse succeeds.
- Copy or download the file (extension follows the language), then run it once in the same environment before refactoring headers into shared clients.
2. Where this saves time
Chrome or Firefox “Copy as cURL” becomes project code without hand-rewriting Authorization and Content-Type. Documentation samples become stubs you can commit behind environment variables. Comparing how the same request looks in fetch versus requests clarifies header and body conventions across stacks. This page is not an OpenAPI client generator and will not invent middleware stacks for you.
- Prefer DevTools copy over retyping long JWTs by hand.
- Redact secrets in the paste before screen shares or chat.
- After generation, replace literals with config or env lookups your repo already uses.
3. Must-check after convert
Shell escaping can mangle URLs and JSON bodies — spot-check the URL and one known field in the generated payload. Multipart file uploads (-F) often need manual finishing because path and stream semantics differ per language. Cookies and Authorization headers should not land in public repositories; use placeholders. Generated code is a starting point: wire timeouts, error handling, and base URLs the way your team already does.
- Compare generated method and path to the original curl flags.
- For uploads, expect to finish multipart assembly in your HTTP client.
- Never leave production Bearer tokens in committed samples.
4. Language coverage and idioms
js-fetch mirrors the Fetch API; js-axios uses Axios call shapes; python targets requests; java uses HttpClient-style calls; go uses net/http. Choosing the client your service already depends on avoids a second translation later. If your stack wraps fetch thinly, still generate vanilla fetch here and adapt once — usually faster than fighting a half-matching template. Curl-to-curl mode helps when you only need normalized quoting before sharing with a teammate.
5. Safety and clipboard hygiene
Curl snippets from staging often carry real tokens, session cookies, or internal hostnames. Conversion stays in the browser, but clipboard history, screenshots, and chat pastes still leak. Scrub Authorization and Cookie headers before you share the generated file. Prefer short-lived test credentials when demonstrating the tool on a call.
6. Pair with the API tester
Validate the request live in the API tester (leave the server proxy on when CORS blocks the browser), then copy as curl and generate language code here — or reverse the loop: generate code, then replay the same curl in the tester to confirm status and body shape. Clear secrets from tester history after demos. Acceptance: one known endpoint returns the same status code and a matching JSON field in both the tester and a one-off run of the generated snippet.
7. Failure samples worth rehearsing
When the generated snippet fails while the original curl worked, diff method, URL, and the first request header before rewriting business logic. Most misses are paste fidelity, not language choice.
- A URL with unescaped & inside single quotes in the shell but double quotes in the paste — method looks right, query is truncated.
- A -H line split across continuations without a space — header name glues to the previous value.
- Binary --data-binary @file paths do not travel with the paste; regenerate after attaching the file in code.
FAQ
When a backend engineer or an API doc hands you a curl and you need project code: paste it, pick the language, and get a runnable draft — prove it out in the same environment first, then refactor. Turning the DevTools "Copy as cURL" output into code is its home turf; just do not treat it as a full SDK generator.
Six outputs: JavaScript (Fetch API), JavaScript (Axios), Python (requests), Java (HttpClient), Go (net/http), plus the curl itself tidied up — pick the client your team already uses and skip a layer of re-translation.
The common set: -X / --request (method), -H / --header (headers), -d / --data / --data-raw (body), -u / --user (Basic auth), -G / --get (force GET), and more. Keep the original quotes and backslash line-continuations when pasting.
As a starting point yes, as the final form no. Three checks before landing: whether the URL survived shell escaping, whether file uploads and multipart need manual work, and whether cookies or auth headers belong in the repo at all — swap secrets to environment variables before sharing or committing.
Parsing and generation happen inside this page, so the command and endpoint never leave your machine; the generated code still carries the real token, though — redact it before sharing or committing.
