For quick analyses, it's brilliant. Quick and easy.
Sure, I could write a full set of requirements, drop into the queue, assign to a DBA in the next sprint, go through the refinements, and they could build me something, and in two weeks it might be what I want. Or not.
Or I could put it in Excel do a few pivot tables and some lookups and ten minutes later have results.
I wouldn't use it for a production system, of course, and even I did, I wouldn't admit to it.
