cURL to Code Converter
Paste a cURL command below to instantly translate it into production-ready code. This tool runs entirely in your browser, meaning your API keys, bearer tokens, and sensitive headers are never transmitted to our servers.
How ZeroData protects your privacy
- ✓ No Uploads: Tool input is processed in your browser and is not sent to ZeroData servers.
- ✓ No Storage: Tool input is not saved by this website.
- ✓ No Input Tracking: Analytics never receive the text, files, keys, or credentials you process.
- ✓ Verifiable: Disconnect from the network after the page loads; local tool processing continues without uploading your input.
Quick Solution
Paste your raw cURL command into the input area, select your target programming language (such as Python, Node.js, or Go), and instantly copy the translated, production-ready HTTP request code for your application.
When Should I Use This?
Translating shell commands to application code is highly useful for rapidly prototyping integrations and debugging network calls.
- Translating Postman or browser cURL exports directly into production-ready API integration code.
- Rapidly onboarding developers to APIs by providing copy-pasteable examples in their native language.
- Documenting API examples systematically by converting a single cURL source of truth into multiple language snippets.
Troubleshooting
Issue: Parse error caused by escaped quotes breaking the command
Fix: Windows CMD uses double quotes (") and carets (^), which often conflict with bash parsers. Always copy the cURL command using bash syntax (single quotes and backslashes) from your browser's DevTools to ensure flawless parsing.
Issue: --data-binary or raw payloads not converting correctly
Fix: Check your Content-Type header. If you are sending binary files or raw bytes, ensure your code explicitly sets the correct MIME type (like application/octet-stream) and that your HTTP client library in the target language supports binary payload streams rather than just JSON dictionaries.
How to Get a cURL Command from Your Browser
The easiest way to generate API integration code is by capturing requests directly from your browser's developer tools. This ensures you capture all necessary cookies, authorization tokens, and exact headers that the web application uses.
- Open your browser's Developer Tools (F12) and navigate to the Network tab.
- Ensure the network recording is active, then perform the specific action on the website (e.g., submitting a form, clicking a button, or loading a data table).
- Find the specific network request in the list. You can filter by "Fetch/XHR" to hide images and stylesheets.
- Right-Click the target request, select Copy, and then choose Copy as cURL (bash).
- Paste the cURL command into the converter above to immediately generate equivalent code in your target programming language.
How It Works: Converting cURL to Code
Translating shell commands into structured HTTP client code requires precise parsing. Here is exactly how the converter interprets your input:
- Tokenization: The tool breaks down the raw cURL string into discrete tokens, respecting quotes, escaped characters, and multi-line backslash continuations.
- Flag Extraction: It identifies key HTTP components from shell flags, such as
-Xfor the HTTP method (GET, POST, PUT, DELETE) and-Hfor headers. - Payload Processing: Data arguments provided via
-d,--data, or--data-raware parsed. The converter intelligently formats this payload into JSON objects or form-urlencoded strings depending on theContent-Typeheader. - Authentication Handling: Flags like
-u(Basic Auth) or headers containing Bearer tokens are mapped into standard HTTP authorization configurations for the target language. - Code Generation: Finally, the extracted request blueprint is passed through language-specific templates to produce native code for Python Requests, JavaScript Fetch, Go
net/http, or PHP cURL.
5 Practical Use Cases
Developers use this cURL conversion tool daily to accelerate API integration workflows:
- Replicating Undocumented APIs: By capturing a web application's internal network requests in Chrome DevTools, you can instantly generate a Python web scraping script without hunting for API documentation.
- Migrating from Postman: Exporting saved Postman collections as cURL commands and converting them into Node.js
fetchblocks to drop directly into your backend services. - Building Automated Tests: Grabbing a failed API request from server logs and translating it into a JavaScript test case to reproduce and fix the bug locally.
- Creating CLI Tools in Go: Taking standard cURL examples provided by SaaS vendors (like Stripe or Twilio) and converting them into native Go
http.Clientcode for high-performance microservices. - Debugging Authentication Issues: Quickly checking how a complex OAuth flow translates into code by comparing a working cURL request with your application's failing code structure.
Frequently Asked Questions (FAQ)
How do I get a cURL command from my browser?
Open your browser's Developer Tools (F12), navigate to the Network tab, perform the action on the website, find the specific network request, right-click it, and select Copy → Copy as cURL (bash). Then paste it into this converter.
Is it safe to paste cURL commands containing API keys and tokens?
Yes. This tool parses your cURL command completely locally in your browser using JavaScript. No data — including your Authorization headers, Bearer tokens, or session cookies — is ever transmitted to a server.
What output languages are supported?
This tool currently supports JavaScript (Fetch API), Node.js (node-fetch), Python (Requests library), Go (net/http), and PHP (cURL). We continuously add more language templates to support diverse engineering stacks.
Can I convert complex cURL commands with multiple headers and data?
Yes. The parser handles common cURL flags including -X (method), -H (headers), -d (data/body), -u (basic auth), --data-raw, --compressed, -b (cookies), and -L (follow redirects). Multi-line commands with backslash continuation are also fully supported.
Why does the converter show an error for my cURL command?
The most common cause is Windows-style cURL syntax (using double quotes and carets for line breaks) instead of bash-style (single quotes and backslashes). Try reformatting your command to use bash conventions, or ensure you select "Copy as cURL (bash)" in Chrome DevTools.
How does it handle JSON payloads?
If the cURL command includes a Content-Type: application/json header, the converter attempts to parse the payload and output it as a native dictionary or object in your chosen language, making the generated code much cleaner.
ZeroData Privacy Moat: Why Privacy Matters
cURL commands almost always contain highly sensitive data, such as Authorization: Bearer ... headers, production API keys, or active session cookies. Most online cURL converters send your command to a backend server to process, exposing your credentials to third-party logs. 100% private — your cURL commands never leave your browser. The entire tokenization and code generation process runs locally on your machine.
While working with APIs, you might also need our JSON Formatter to clean up response payloads, our URL Encoder to safely pass parameters, or our JWT Debugger to inspect authorization tokens locally.
Browser Compatibility
This tool is fully compatible with modern web browsers, including Chrome, Firefox, Safari, and Edge. The parsing engine relies on standard ES6 JavaScript features, ensuring that the conversion executes swiftly and reliably without needing a backend server or heavy WebAssembly modules.
