One of my previous work places with an auditing data set company. We'd collect data sets from various sources (like public filings from the SEC) and the we'd send them over to different research teams to enrich the data in various ways. That company was very Excel heavy - which made sense, we had data entry, accountants, and other people who worked in finance. My CTO told me a story about how one day a member of a research team asked for a new computer. The old computer worked fine, but the employee wrote a VBA script in Excel that would crunch data... and wouldn't finish until 3 days later. This employee wanted a new computer so that he had one to use while the other one was crunching data. We ended up taking his VBA script and putting it into our codebase.
