Custom Number Category Formatting Cells

[lanespoli]

So I had to add a prefix to a bunch of numbers which I did using the "Custom" feature under numbers in the format cells section and it worked GREAT. The problem though is my CSV file is going to be imported into a program and I can't get these numbers to just be "numbers" now. Does anyone know if that will affect the import?

I've attached the worksheet here. Thanks your help is appreciated!
