What formatting features does the Kotlin Code Formatter offer?

The tool provides comprehensive Kotlin formatting including JetBrains coding standards compliance, automatic indentation, import organization, data class formatting, extension function formatting, coroutine support, nullable type handling, and when expression formatting. Perfect for Android development and Spring Boot backend projects.

How do I format my Kotlin code using this tool?

Simply paste your Kotlin code into the input editor, select your project type (Android/Spring Boot/Multiplatform), customize formatting settings (function style, data classes, coroutines), and click "Format Code". The tool applies modern Kotlin conventions instantly.

Is the Kotlin formatter compatible with Android, Spring Boot, and multiplatform projects?

Yes, the formatter supports all Kotlin platforms including Android development, Spring Boot backend services, Kotlin Multiplatform projects, and general Kotlin applications. It includes specific formatting rules for each platform and works on all browsers.

Are there any limitations for enterprise Kotlin code formatting?
