I'm creating a spreadsheet which I need to input upc codes for products. Every time I type in upc numbers and press tab or enter. The numbers I've typed turn into decimal numbers. Is there a way excel can just let me input my numbers without it doing something to the numbers. I turned off automatic calculations thinking that may help but it didn't help my the numbers stay the same I typed. How can I stop excel from doing something to the numbers I type.
