I've been working with Excel spreadsheet data created from SAP and I've
noticed that number values can't be used as-is. Also, when I try and write
an equation (ex =9*9) in one of the cells of the imported data, it doesn't
calcuate it, it just shows =9*9. The only way I can get number values to
calculate properly is by going into each cell and hitting enter.

Is there some type of formating change I can make to correct this problem?
