Possible to read csv to nested data class hierarchy? about dataframe HOT 1 CLOSED

Hi! I would split the problem into two parts:

1. Read CSV into a dataframe with nested hierarchy. Here we have two options:
   i) read flat CSV and use https://kotlin.github.io/dataframe/group.html to create nesting.
   ii) if cells of your CSV contain JSON values, then dataframe will read them into ColumnGroup (value is object) or FrameColumn (value is array of objects). It's not mentioned in the current version of the documentation, i will publish an update :)
2. Get a list of a data class instances from the dataframe with nested hierarchy: https://kotlin.github.io/dataframe/collectionsinterop.html#interop-with-data-classes

from dataframe.
