Convert curl commands into production-ready code

Paste any curl snippet and instantly generate idiomatic code for HTTP libraries you already use. The converter keeps authentication headers, multipart payloads, and TLS flags intact so you can move from terminal experiments to automated tests without rewriting requests by hand.

Why developers translate curl

Most API exploration starts with curl because it is ubiquitous, scriptable, and easy to share on Slack or in tickets. The challenge arrives when you need to embed that request inside a frontend, a serverless function, or your load-testing suite. Copying headers manually is error-prone, and forgetting to convert quoting or escape sequences leads to subtle bugs.

The Curl to Code converter analyzes the request line, infers the HTTP method, and inspects payload flags to determine whether the body should be JSON, multipart form data, or raw binary buffers. It then maps each piece into Fetch, Axios, Python Requests, Go net/http, or PHP curl syntax with consistent naming. The output is formatted for readability, making it safe to drop into pull requests.

  • Accurate headers

    Authorization, custom tracing IDs, and cookies are preserved, de-duplicated, and sorted to match language conventions.

  • Smart body handling

    Detects JSON payloads, file uploads, and URL-encoded data before serializing them through the matching helper in each runtime.

Ship code faster

Need to send teammates a working example? The converter adds helpful comments and groups reusable constants so handing off to QA or SDK teams is painless. Every transformation runs in your browser, which means you can test sensitive credentials locally without uploading them to a remote service.

Once the snippet looks correct, copy it directly or launch related FreeTools.run utilities to continue hardening your workflow. Most developers pair the converter with schema validators, mock servers, and documentation tools so that the original curl command and the generated code stay in sync.

  • Language matrix

    JavaScript Fetch or Axios, Node.js native HTTPS, Python Requests, Go net/http, and PHP curl are only a click away.

  • Error-proofing helpers

    Optional `try/catch` scaffolding and timeout settings help you go from prototype to resilient job without rewriting everything.

Power tips

Keep commands source-controlled

Store the original curl statement alongside the generated code so diffs remain obvious during reviews.

Swap out secrets safely

Use environment variables when copying API keys to keep production credentials out of Git history.

Document expected responses

Pair the generated request with JSON samples formatted inside the JSON Formatter to debug payload drift.

Share reproducible repros

Attach both the curl snippet and the translated code to bug reports so backend teams can jump in faster.

Next step

Validate the response schema next

Once you have the request code, run the server response through the JSON Formatter & Validator to confirm field names, ordering, and linting rules before sharing logs with your team.

Frequently asked questions

What is cURL?

cURL is a command-line tool used to transfer data to or from a server. It supports various protocols, including HTTP, HTTPS, FTP, and more. It is widely used for testing APIs.

Why convert cURL commands?

While cURL is great for the terminal, developers often need to replicate those requests in their code. Converting cURL to Python, JavaScript, or Go manually is tedious and error-prone. This tool automates that process.

Which languages are supported?

We support conversion to Python (Requests), JavaScript (Fetch, Axios), Node.js, Go, Java, PHP, Rust, and many more.

Is my API key safe?

Yes. All conversion happens locally in your browser. We never see your cURL commands, headers, or API keys.

How to use cURL to Code Converter – Python, JavaScript, Go & More

Follow these four quick steps to transform data between ecosystems right inside your browser—no downloads, no accounts, and no data leaving the FreeTools.run sandbox.

  1. Step 1: Load your source data

    Paste text, drag a file, or start with our curated sample to understand how the converter workflow behaves with real inputs.

  2. Step 2: Adjust tool options

    Toggle presets, update formatting rules, or choose export preferences. All controls update in real time so you can preview the effect before committing.

  3. Step 3: Review the live preview

    Use the split-pane preview, inline validation, or diff output to confirm the transformation looks correct before you copy anything back into your project.

  4. Step 4: Export or chain another tool

    Copy the result, download a file, or jump into a related FreeTools.run utility (like Diff Checker or the QR Code Generator) to continue the workflow without leaving the browser.
