title: How big is too big?
body: <p>I have a 60mb excel file that has all of the "sins"... Array formulas, VBA and conditional formats. It crashes all the time and it's now being suggested that it's too big. There are about 20 worksheets and 3 of them are 15mb in size and each have about 35,000,000 active cells. Is this why the sheet crashes?</p>
