While this information is still very useful, 64-bit Access more-or-less serves the same purpose but works a lot better for what we were doing with it (i.e. loading giant flat files to visualize things in Excel). THAT SAID, I would go as far as to say, next to learning XLOOKUP, PowerPivot was possibly the most important thing I could have taught... Why, you ask? Simple: Power BI uses the same interface to do a hell of a lot more.
