Get Data From Picture (File/Clipboard)

Hi!

My objective is to compare the list of columns in two different data sources/tables in Tableau to swap the source.

My plan: Get screenshots of the fields in the two tables and use Excel (Get Data -> From File/Clipboard) to extract the columns from the screenshots and compare them.

However, "Get Data" is getting stuck at 20% always when I am trying. The same happens for From File as well as From Clipboard.

I'm wondering whether the champs in this group have any tried and tested hacks to Get Data from a picture?

Cheers!
