 ### Overview
 
 This is a very cool tool for Kotlin developers, it can convert a JSON string to Kotlin `data class`. The tool could not only recognize the primitive types but also auto create complex types. It's easily accessible, we provide shortcut keymap `ALT + K` for Windows and `Option + K` for Mac, have a try and you'll fall in love with it! JsonToKotlinClass just makes programming more enjoyable, enjoy coding!
