How do I convert Kotlin code to Groovy step-by-step?

Copy your Kotlin code into the input field, select Kotlin as the source language and Groovy as the target, then click Convert. The tool automatically rewrites statically-typed declarations to dynamic def, removes null-safety operators where appropriate, and adapts function literals to Groovy closures.

Why would I need to convert Kotlin to Groovy?

Groovy is dynamically typed and deeply integrated with Jenkins pipelines and Grails. Converting Kotlin code allows you to reuse existing logic in scripting environments where static typing isn't required, or when migrating a Kotlin-based project to a Groovy stack while preserving algorithmic behavior.

How does the converter handle Kotlin-specific features like null-safety and data classes?

The converter maps Kotlin's nullable types to Groovy's dynamic typing, stripping safe-call (?.) and Elvis (?:) operators because Groovy allows nulls by default. Data classes are converted to Groovy POGOs with @Canonical or @TupleConstructor annotations, preserving equals/hashCode/toString semantics. Lambda expressions become Groovy closures, and companion objects become static methods where appropriate.
