I am not super technical, and DBGuy is well above and beyond me in knowledge. The process I used to set everything up was to use the import wizard to make the table for me when importing the excel sheet. That gave me my template to use. I then append only the data I actually want out of the temp table to a more permanent table. You could then export that table to Excel.
As far as the calculations, I can try and take a peak but at the end of the day I am not very knowledgeable.
