Comment utiliser : JSON to Kotlin
- Paste a JSON sample in the input — Kotlin is already selected.
- Set the root type name and options such as optional fields and date detection.
- Copy the generated Kotlin code into your project.
JSON to Kotlin data classes
Each JSON object becomes a Kotlin data class with val properties; nested objects become their own data classes and arrays become List<T>. Optional fields are nullable with a default of null, and @SerialName keeps the original JSON keys.
Parsing
Mark the classes @Serializable and call Json.decodeFromString<Root>(json) with kotlinx.serialization. Use Json { ignoreUnknownKeys = true } when the API may add fields. The same classes work with Moshi or Gson.
Private by design
The conversion runs entirely in your browser — API responses with customer or internal data are never uploaded.
