Kotlin data classes provide a concise syntax for model classes with auto-generated equals(), hashCode(), and toString(). This generator maps JSON types to Kotlin types: strings → String, integers → Int, decimals → Double, booleans → Boolean, nulls → Any?, arrays → List<T>, and nested objects → nested data classes. Field names are converted from snake_case to camelCase.
