Which browsers are supported?

The cURL to Code Converter works in all modern browsers including Chrome, Firefox, Safari, Edge, and Opera. For the best experience, use the latest version of your preferred browser.

How do I convert a cURL command copied from my browser's DevTools into code?

Most browsers let you right-click any request in the Network panel and choose "Copy as cURL," which captures the exact HTTP call your app made, including headers, cookies, and the request body. Paste that command straight into this converter and pick your target language; it parses the flags and rewrites the same request using that language's standard networking library. This is the fastest way to reproduce a live request inside a script or test without hand-copying every header one by one. The summary line confirms what was detected — the method, URL, header count, query parameters, and any request body or auth type — so you can verify the parse is correct before trusting the output. Paste your "Copy as cURL" string above and copy the generated code into your project.

Does the converter handle authentication headers and bearer tokens?

Yes. The parser reads the cURL -u flag for HTTP basic authentication and translates the user:password pair into the right idiom for your chosen language. It also automatically detects a Bearer token inside an Authorization header and carries it through to the generated request, so token-protected endpoints work without extra editing. API keys passed as custom headers with -H are preserved as well, since headers map directly into the output. A small badge in the summary line flags the auth type it found, letting you confirm the credentials were picked up correctly before you run the code. One caution: the converter copies whatever secret is in your command into the generated source, so swap real tokens for placeholders before committing. Paste your authenticated cURL command above to convert it in seconds.

How does the tool convert a cURL -d JSON body into each language?

When you pass a request body with -d, --data, or --data-raw, the converter inspects the payload and, if it looks like JSON, wraps it using each language's native JSON helper rather than sending a raw string. In JavaScript that means JSON.stringify with a Content-Type header; in Python requests it becomes the json= argument; other targets use their idiomatic equivalent. The HTTP method is inferred as POST when a body is present unless you set one explicitly with -X. This avoids the common mistakes of mis-encoding the payload or forgetting the Content-Type header, which are easy to get subtly wrong by hand. The result is a correct, ready-to-run request instead of a brittle string concatenation. Paste a cURL command with a JSON body above and copy idiomatic code for your language.

Which language and library should I pick — fetch, axios, requests, or httpx?

The converter offers 14 targets so you can match the exact library your project already uses. For JavaScript it generates fetch, axios, or Node.js node-fetch; TypeScript adds a typed response interface on fetch. Python offers synchronous requests or async httpx, so pick httpx when your code runs inside an async framework. It also covers PHP cURL, Go net/http, Ruby Net::HTTP, Java HttpClient, C# HttpClient, Rust reqwest with tokio, Kotlin OkHttp, and Swift URLSession. Choose the option that fits your stack and concurrency model rather than the most popular one — using your project's existing client keeps dependencies and style consistent. Switching targets regenerates the code instantly, so you can compare outputs side by side. Pick your language above, copy the result, or download it as a file with the correct extension.

Can it convert cURL form uploads and multipart -F file fields?

Yes. The parser understands the -F and --form flags used for multipart form data, including individual form fields and file uploads written in cURL's @filename syntax. Each field is translated into the multipart construct your target language expects, so a command that posts a file is rewritten with the correct form-encoding rather than being dropped or flattened into a plain body. The summary line shows a form-data badge when it detects these fields, confirming the parse before you copy the code. This is useful when an API reference documents an upload as a curl one-liner and you need the equivalent request in your application. Because the @filename reference points at a local path, set that path correctly in your environment after pasting. Drop your multipart cURL command above to generate the upload code.

About the cURL to Code Converter

The cURL to Code Converter turns a curl command into ready-to-run source code in your chosen programming language. Paste the command you copied from API docs, a terminal, or your browser's network panel, and the tool parses it and rewrites the same HTTP request using each language's standard networking library. It is built for backend and frontend developers, QA engineers, and anyone who finds a working curl example online but needs to call that endpoint from an actual codebase.

Everything happens in your browser. The command is parsed and the code is generated locally as you type, so nothing you paste — URLs, tokens, cookies, or request bodies — is ever sent to a server. There is no sign-up, no API key, and no installation.

Languages and libraries it generates

The converter produces idiomatic code for 14 targets, grouped by language so you can pick the exact library your project uses:

  • JavaScript — fetch, axios, and Node.js node-fetch
  • TypeScript — fetch with a typed response interface
  • Python — requests and async httpx
  • PHP — native cURL bindings
  • Go — net/http
  • Ruby — Net::HTTP
  • Java — the built-in HttpClient
  • C# — HttpClient
  • Rust — reqwest with tokio
  • Kotlin — OkHttp
  • Swift — URLSession

Switching targets regenerates the code instantly, and you can copy it to the clipboard or download it as a file with the correct extension (.js, .py, .go, and so on).

What the parser understands

cURL is the de facto language for documenting HTTP requests, but its flags do not map one-to-one onto any single library. The converter reads the common options and translates each one into the right idiom for the target:

  • -X sets the HTTP method (GET, POST, PUT, DELETE, and others); it is inferred as POST when a body or form is present.
  • -H request headers, including multiple headers on a multi-line command.
  • -d / --data / --data-raw the request body; a JSON-looking payload is wrapped with the language's JSON helper (for example JSON.stringify or Python's json= argument).
  • -F / --form multipart form fields, including file uploads written as @filename.
  • -u basic authentication, plus automatic detection of Bearer tokens inside an Authorization header.
  • -b / --cookie and -A / --user-agent are folded into the generated request headers.
  • -L / --location, -k / --insecure, and --compressed flags are recognized, and query parameters in the URL are parsed out separately.

As you edit the command, a summary line shows what was detected — the method, the URL, how many headers and query parameters were found, and badges for a request body, auth type, cookies, or form data — so you can confirm the parse before trusting the output.

Why convert cURL to code

A curl command is the most portable way to share an HTTP request: every API reference, Stripe doc, and Stack Overflow answer uses it. The problem comes when you have to move that one-liner into a real application. Hand-translating headers, body encoding, and authentication into fetch or requests is tedious and easy to get subtly wrong — a missing Content-Type, mis-encoded JSON, or auth header in the wrong place. Generating the code removes that friction and gives you a correct starting point in seconds.

It is just as useful in reverse-engineering workflows. Most browsers let you right-click a request in DevTools and choose "Copy as cURL"; dropping that into the converter is a fast way to reproduce a live request — the one your app actually sends — inside a script or test.

Paste a cURL command above, pick your language, and copy the generated request straight into your project.
