Is using the features present in Excel now considered abuse? In my position, I see and create a lot of Excel documents specifically because I can create OLEDB connections to transactional systems, aggregate information, and create visualizations all in one place without having to go through the long, painful, and often flawed process of creating a data warehouse / data marts, creating SSIS connections between all the difference sources, then use another product such as Tableau or even SSRS to run the summaries. While all of that is getting set up, the organization gets no visibility into current trends, etc. It's significantly faster to get a dedicated report using scripts created in Excel, even if it's a much worse solution in the long run. From what I've seen, LibreOffice doesn't even have the capabilities to do this kind of work.
