What is JSON to Kotlin Data Class?
JSON to Kotlin data class tool can automatically generate Kotlin data class definitions based on JSON data. Generated data classes include correct type annotations, leveraging Kotlin null safety features to handle potentially null fields. The tool supports nested object generation for nested data classes, and array types automatically map to Kotlin List. Generated code can be directly used in Android development or Kotlin backend projects.
