Paste a curl command, get JS fetch / Python requests / Node axios / PHP cURL / Go net/http — parsed locally, instant
- Runs locally
- Category Developer & DevOps
- Best for Formatting, validating, shrinking, or inspecting code-adjacent text.
Everything runs in your browser — the curl string is parsed locally with a small lexer, no request is ever sent and nothing is uploaded. One caveat: the curl text is synced into the page URL so a share link reproduces it, so if your command contains a bearer token or password, copy the output manually rather than sharing the link.
What this tool does
Paste any curl command and get clean, idiomatic source code in five languages: JavaScript fetch, Python requests, Node axios, PHP cURL, and Go net/http. The parser is a small shell-aware lexer that understands single quotes, double quotes, backslash escapes, and the `\` line continuation real-world snippets use — so a multi-line copy-paste from an API doc just works. It reads `-X` / `--request` for the method, every `-H` / `--header`, the body from `-d` / `--data` / `--data-raw` / `--data-binary`, basic auth from `-u`, multipart fields from `-F`, and splits the URL's query string out so you can see the params at a glance. When the Content-Type is JSON and the body parses, the generated code pretty-prints it (and converts true/false/null to Python's True/False/None). Strings are escaped per target language, so the output pastes straight into a file without hand-fixing quotes. Everything runs in your browser — no request is ever sent, nothing is uploaded. The curl text syncs into the URL so a share link reproduces your conversion.

How curl to Code Converter fits into your work
Use it in the small gaps between coding, reviewing, debugging, and shipping.
Developer jobs
- Formatting, validating, shrinking, or inspecting code-adjacent text.
- Preparing snippets for documentation, tickets, commits, or handoff.
- Checking a small payload quickly without switching tools.
Developer checks
- Run irreversible transforms like minify or obfuscate on a copy.
- Keep secrets out of pasted snippets unless the tool explicitly stays local.
- Use your normal tests or linter before shipping transformed code.

Real-world use cases
Lift a request straight out of API docs into your codebase
Stripe, OpenAI, GitHub — almost every API reference gives you a ready curl command. Copy it, paste it here, switch the target to Python or Go, and you have a working call in your project's language without retyping headers or hand-escaping the JSON body. The Authorization header and Content-Type come across exactly as the docs wrote them, so the first run usually just works.
Turn a debugging curl into production code
You hit a flaky endpoint with a one-off curl in the terminal, added a header, tweaked the body, hit it again until it returned 200. Now you need that exact request in the app. Paste the final curl, pick fetch or axios, and the generated code mirrors the request that worked — same method, same headers, same body — instead of you reconstructing it from shell history by memory.
Hand a backend call to a frontend dev (or vice versa)
A backend engineer shares a curl that hits an internal service. The frontend dev needs it as fetch. Drop the curl in, copy the fetch output, done — no "what's the exact header casing?" back and forth. The parsed summary up top shows method, URL, header count and query params so both people are reading the same request.
Teach or document an HTTP request in five languages at once
Writing a tutorial or an internal runbook that should show the same call in curl, Python, and Node? Author it once as curl, then flip the target selector to capture each language's idiomatic version. Because the share URL carries the curl text, you can drop a single link in the doc and readers land on the exact request, then switch to whatever language they work in.
Sanity-check what a copied curl actually does
A teammate pastes a wall-of-text curl in chat. Before you run it, paste it here: the summary breaks out the method, the real URL, how many headers it sets, whether it carries basic auth, and the decoded query parameters. You see at a glance that it's a POST with a bearer token to a third-party host — useful before you blindly execute a command someone handed you.
Common pitfalls
A bare `curl https://x` with no `-X` and no body generates a GET — that's correct. But if you intend a POST with an empty body, curl itself needs `-X POST`; adding a `-d ''` here will flip the inferred method to POST, matching curl's own behavior. Don't expect a magic POST from an empty command.
Pasting a curl that was wrapped for a Windows `cmd` shell (using `^` line continuations and double quotes everywhere) can mis-tokenize. This tool targets bash/zsh-style snippets with `\` continuations and single-quoted args, which is what API docs and the "Copy as cURL" browser feature emit. Re-copy from a bash context if the parse looks off.
The generated Go body uses a backtick raw string literal. If your JSON body itself contains a backtick (rare), the output inserts a string-concatenation break to stay valid — review that one line. For fetch/axios/Python the body is a normally escaped string, so backticks there are a non-issue.
Privacy
The shell lexer and all five code generators are plain JavaScript that runs in your browser tab. Your curl command is never sent anywhere — no request is executed, no analytics on what you converted, no logging. The one privacy caveat: the curl text is encoded into the shareable URL query string so a "share link" reproduces your exact conversion. That means if your command contains a bearer token, API key, session cookie, or a `-u user:password`, pasting the share link into Slack or email will leave that secret in the destination server's access log. For commands with secrets, copy the generated code manually instead of sharing the URL, or strip the credential before sharing.
