I was going to post much the same regarding SQL <> Excel. Once underlying data sources are cleaned, wrangled, and access-controlled, it's amazing how far VLOOKUP and Pivots will get you.
I've also found that giving non-technical users the opportunity to self-serve when more than one data source is involved always leads to offline mashups of data and the question - "Hey data team, why doesn't 'your' data match 'mine'", always with the assumption that 'theirs' is the correct one!
