Pasting Clip Board Data into Object Lists

Hi together,

I managed to create a custom widget, where I can paste data an display it as a simple html Table.
I now want to hand this data over to the App as Object List.

One issue is, that I can’t predict the dimensions (rows, columns).
However I wasn’t even able to realize this with a reasonable effort for two known columns.
(I don’t know how to send my whole array to an event Object List)

Has anyone done something similar?
Are there any ideas?

Here is a preview of my prototype, so it is not ment to be a beauty yet :sweat_smile:
