So I had the opposite experience-- learned to do all my data processing in undergrad+grad school for physics using Python. Moved out to my first industry job developing simulations and learned that everyone (other scientists, management, etc) would rather me process results in excel (unless we were working on a database scale, in which case we used postgres). I actually had to learn excel properly for the first time for this job.

I'm now at another large university-affiliated research lab and excel is king here as well, though I can get away with using Matlab generated plots in my slides when I'm working solo. People still don't like python for some reason.

I had a similar experience with paper writing-- in academics it was conventional to do everything in LaTeX from my first lab courses in freshman year. In both workplaces, we've just been using word.

And it's not that people don't know python/latex here-- we've just apparently developed a culture of using these matlab/excel/word tools instead.
