Sure, we techy types prefer a proper database with a web frontend and an API, but that requires significantly more skill to build than an excel file.
No database has the flexibility and flat learning curve that excel has.
Until a database manages to meet these goals, it remains a good tool for certain usecases.
We as engineers should be working towards making a real database thats just as easy to use as excel, and only then can we complain that people are using excel sheets for this kind of stuff.
