What I've learned from talking with folks is that one thing that they like about Excel is that they can see what data they have and then go and build charts, graphs, or pivot tables from it. And it's not so apparent in Tableau. While Tableau is all about the data, it seems to be more about data discovery while putting the data on the view. That works for a lot of folks. But there are others that are bridging the gap from another tool to Tableau or they want to know what they're working with before they actually build something.
So, I found five easy peasy ways to see the data (and there are others, I'm sure).
