HELLO world, this is my first post and heres my problem.
I have an excel spreadsheet with 22 columns, and undefined amount of rows. I need vb.net to read the data from excel. Then use that data to populate an existing access database table that has been added to visual studio. I've tried multiple approaches and have come to a standstill.
this was approach 1
Heres another failed approach
