I've seen and heard from colleagues that there is a lot of data being stored and shared in CSV too ..and then analysis done in excel.

that seems to change as an automation and IT culture starts to develop in an organization; interestingly, IT can sometimes be a barrier to data organization (too slow, cross-org costs etc) and cause people to continue to use CSV and excel.

fwiw - we built a service called "yukon data solutions" that solves these classes of problems for people trying to transition from CSV and spreadsheets into automated and reproducible analytics and reporting.
