What CURL inputs does this converter accept?

Paste any valid CURL — including API testing, browser DevTools request copying, documentation examples, shell automation. The converter infers types and generates a matching R httr model.

What serialization library does the generated R httr code assume?

The generated code is compatible with the standard R httr serialization ecosystem — httr-style calls with headers, method, and body. No unusual dependencies required.

What version of R httr does the output target?

The converter targets modern R httr conventions — httr-style calls with headers, method, and body. If you need output for an older version, the generated code can typically be adapted with minor changes.

Why automate cURL-to-R conversion?

Writing R HTTP client code from scratch based on a cURL command is:

Tedious — manually translating flags, headers, and body formats
Error-prone — easy to miss headers, mistype URLs, or forget auth
Slow — copying from browser DevTools and reformatting takes time

This converter does it instantly — paste cURL, get R code.

What the converter handles

All HTTP methods (GET, POST, PUT, PATCH, DELETE, HEAD, OPTIONS)
Request headers and body (JSON, form-data, binary)
Authentication (basic auth, bearer tokens, API keys)
Cookies and session handling
Query parameters
Custom user agents

Common use cases

Converting cURL from browser DevTools to R code
Translating API documentation examples to R
Generating boilerplate HTTP client code
Sharing API requests with team members who use R
Migrating shell scripts to R applications

Frequently asked questions

Does this support all cURL flags?

The converter supports all common HTTP-related cURL flags including -X, -H, -d, --data-raw, -F, -u, -b, -A, and --compressed. Shell-specific features like environment variables and subcommands may not be fully supported.

Is my cURL data sent to a server?

No. All conversion runs locally in your browser using client-side JavaScript and WebAssembly. Your cURL command never leaves your machine.

Can I use the output directly in my R project?

Yes. The generated code follows idiomatic R patterns and is ready to paste into your project.

Does this work with large or complex cURL commands?

Yes. The converter handles multi-line cURL commands, complex headers, and large request bodies — all processed locally in your browser.
