The encodeToString() function is provided by the Kotlin Serialization library. It is used for serializing data to a string representation (commonly in JSON format).


fun <T> encodeToString(serializer: SerializationStrategy<T>, value: T): String
  • serializer: An instance of SerializationStrategy that defines how the data should be serialized.
  • value: The object or data to be serialized to a string.


Here is an example of how to use encodeToString() to serialize data into a JSON string:

import kotlinx.serialization.Serializable
import kotlinx.serialization.encodeToString
import kotlinx.serialization.json.Json
data class Person(val name: String, val age: Int)
fun main() {
val person = Person("Johnny", 30)
// Serialize the data class to a JSON string using encodeToString()
val jsonString = Json.encodeToString(person)

This will print the following output:

"name": "Johnny",
"age": 30
