kotlinx.serialization

Try it in 3 steps

1. 1

   Enable the compiler plugin

   In an existing Kotlin/JVM Gradle project, use Kotlin 2.3.20 for both Kotlin and the serialization compiler plugin.

   plugins { kotlin("jvm") version "2.3.20" kotlin("plugin.serialization") version "2.3.20" }Copy
2. 2

   Add the JSON library

   Add it to the Gradle dependencies block and use mavenCentral().

   implementation("org.jetbrains.kotlinx:kotlinx-serialization-json:1.11.0")Copy
3. 3

   Encode and decode a typed value

   Import kotlinx.serialization.* and kotlinx.serialization.json.*, declare Project at file scope, and run the conversion inside main.

   @Serializable data class Project(val name: String, val language: String) fun main() { val text = Json.encodeToString(Project("demo", "Kotlin")) println(Json.decodeFromString<Project>(text)) }Copy
