It depend on your morphology I guess: for me below 15km rides, I can wear jeans and it’s fine, but above that it starts to be painful. When I’m touring I really enjoy having my cycling pant, even a cheap one does the job perfectly for me. But again, I have a quite large distance between my ischium bones, so the same may not apply to everyone.
Where I was working Excel was used for the specification of scientific data. You get stuff like thousands of rows in several sheets themselves in multiple files that inherit from one another and everything is edited by hand… And I maintained a tool that combined them to create binary files from this mess. Lot of fun.
