Level: Beginners Edit: Sep 2019 There are many best practices for Power BI. I know these things so intuitively now that it is very easy to forget how I incrementally learnt these things along the journey. Most of these things are not “right” vs “wrong” – they are more often […]

Level: Beginners I was chatting to Avi Singh the other day and we were comparing notes about the live Power Pivot training classes we both offer in Australia (me) and the USA (Avi). One thing we both have in common is that the Microsoft Excel Power Pivot Add-In CRASHES a lot during training! […]

Level: Intermediate Last week at my Sydney training course, one of the students asked me a question about LASTNONBLANK. This reminded me what a trickily deceptive function LASTNONBLANK is.

Microsoft has released a couple of long over due fixes to some long standing Excel 2013 bugs, both of which have been quite painful in their own way. Unfortunately for me the timing couldn’t have been worse. I literally just placed the order for the print run of my new […]
