Dude.... I know how to use excel, right down to the .net objects using C# to build spread sheets without using the GUI Excel interface. I've also spent a number of years in a past life data mining very large databases with shipping/finance/customs data and dumping results into Excel by code as a way of presenting the data. and.. I've also done work for computershare who manage databases for the ASX.
Trust me! I know the difference between a spreadsheet and a database
