I love what you can do with a cube in Tableau.
However, I can't find a way to import already aggregated data. For instance, I have a spreadsheet that has in each row some columns that are dimension values and some columns that are measures. I.e. a projection of a data cube where each row corresponds to a cell.
Why do I want to do this? Why not import the disaggregated data and do the aggregation in Tableau?
So far as I can see, I can import only raw disaggregated data or aggregate data in esoteric proprietary formats like Essbase. But maybe I'm not looking carefullly enough into the functions of Tableau.
