I work for a bank, and literally almost everyone I work with does this. By comparison, I use R for pretty much everything (minus some formatting in Excel). I have a far easier time identifying errors because than my coworkers, because instead of getting version 328 of Book 1.xlsx with no information about structure, edge cases, etc., I have well-documented code explaining exactly what came in, how I transformed and analyzed it, and exactly what went out. I will say the one downside to this practice is that I get stuck editing a bunch of connector code because no one can send the same information in the same format twice.
