A very light introduction to managing data in Excel with PowerPivot and PowerQuery, the information is clear and a stepwise introduction to managing these Excel add-ins.
I miss some real life example usage, some troubleshooting when one tries to establish relations within tables and it does not work, some more detailed information about using DAX and PowerPivot, ..... , and it keeps surprising me the "generous" waste of paper with margins and pages half empty ...
In my opinion, too expensive for what you get.
