Word is a pain in the ass. Resize a table column by 1px and the rest of the document gets absolutely fucked
Excel suffers from similarly frustrating UI issues, but my main problem with it is that it’s being used for things that it was never intended to be used for. On the extreme side, a company will shove all their HR info into one xlsx file and then someone will accidentally, somehow unrecoverably, delete it
More commonly, I’ve had to use it as a progress tracking/ticketing tool. An entire team adding rows, deleting rows, accidentally clearing formulas, highlighting random fucking cells, resizing columns etc. all at the same time. It’s just hell.
