Hi, n00b Kotlin dev here:
Is there a way to convert the `val`s in the @Serializable data class while encoding?
e.g. Given a data class: data class MyClass(val accessible: Boolean) and given the input JSON { "accessible": "yes" } , can we convert the accessible to Boolean from String while encoding?

I tried the Primitive Serializer but my JSON has several other properties and I can’t seem to figure out how to write the deserialize(decoder: Decoder) function to convert the values to Bool

You can use @Serializable(with = MySerializer::class) on a property if that's what you mean. See https://github.com/Kotlin/kotlinx.serialization/blob/master/docs/serializers.md#specifying-serializer-on-a-property

I solved it using KSerializer and overriding deserialize()
I casted decoder to jsonDecoder and then got the keys and transformed manually.

@rnett Your solution is much more elegant, thanks!
