IMHO, speaking from a data engineer perspective. Excel is used excessively by industry specialists who aren't in IT or but IT people who are being constrained by environment. As in they don't have a better tool to work in. It is a great tool to quickly mock up a report.

Why am I am not good at excel, it is because I am the person who tends to fetch the data from the different systems and consolidates it for the analysts to analyse and some do use Excel to analyse the data.
