This excel that I've been working on has become too large and it runs Extremely slow. It's almost 30 mb and my computer isn't the best. The weird thing is, I have gotten rid of all macros, saved it as a non-macro enabled workbook; and I have deleted the majority of the data. But the file size isn't shrinking. There's no formulas. I tried deleting rows even. What else can make a file so large?
