I really don't mind people sending me stuff in a spreadsheet, if it's something that warrants such use.
Things like "I’ve had screenshots pasted into Excel and attached to an email. Excel is an ubiquitous file format" mentioned in the article is frustrating as well, as particularly in Japan, there's this weird practice of using it as graphing paper, by making each cell into tiny squares, and use it as free-form word processor alternative. (I'd say, PowerPoint would work better for this -- here's the thing, lowest tier of MS Office in Japan doesn't ship with PowerPoint, ugh.) Some of these misuses are actually harmful -- "graphing paper" usage of Excel causes a lot of trouble when it comes to printing, and long-term maintaining, and there's no document structures in such use.
