Have you checked the 'Advanced Editor' in power query? I know for csv files this needs to be manually updated when new columns are added or removed, not sure about excel.

It seems that it reads the columns from Excel even after last column that has data, it reads other columns even thou they are empty

It is simple Excel file. 

I want to be sure that they won't appear when i load new excel file source.
