When you say you want to union two "extracts", I assume you are talking about Tableau extracts (TDE or HYPER)?
Yes, I have two Tableau extracts (TDE) with same columns and I want to union those two.
I know that using the python extract API will convert the TDE format to hyper but tableau 10.5 knows how to read hyper so it doesn't matter to with which file i'll have in the end.
In Tableau Desktop, in the top left "Data" pane, right click on your extract, then select "Extract", the "Append from File"
That should do it !
