How do I convert Ruby (.rb) code to Kotlin (.kt) using LetsConvert?

Upload your .rb file or paste the code into the editor on the page, then click 'Convert'. Our tool transforms it into Kotlin syntax, preserving logic and comments. Finally, download the .kt file or copy it to your clipboard.

Why would I convert Ruby to Kotlin?

Kotlin is the primary language for Android development and offers static typing, null safety, and seamless Java interop. Converting Ruby to Kotlin lets you reuse server-side logic in mobile apps, improve performance, and catch errors at compile time instead of runtime.

How does the conversion handle Ruby's dynamic features like duck typing and metaprogramming?

Our converter maps Ruby's loose variable types to Kotlin's nullable types, so a variable that could be nil becomes a nullable type. It translates blocks to higher-order functions and lambdas, and for metaprogramming, it generates explicit Kotlin code with reflection where necessary, ensuring the output remains functional and idiomatic.
