User Guide: Auto-Generating Kotlin Data Classes from JSON
What is JSON to Kotlin Data Class Conversion?
Kotlin simplifies model files using data class structures. Android development libraries (like GSON, Jackson, or Kotlin Serialization) require these class objects to parse server payloads. This utility reads your JSON keys recursively and formats correct, safe data classes client-side.
Step-by-Step Instructions
- Enter JSON: Paste your structured response list or object map inside the input panel.
- Adjust Settings: Choose package namespace, set base class name, and toggle property nullability.
- Save Class: The compiler outputs standard Kotlin code. Copy or download as a `.kt` file.
Kotlin Null-Safety and GSON tags
Kotlin guarantees compile-time null-safety. By selecting "Use Nullable Fields", the compiler marks properties as nullable (Type?) if values are missing, appending @SerializedName annotations to secure GSON parsing contracts automatically.
