Column headings start at A. After reaching Z, the next is AA, then AB and so on. What the last column is will depend on the version of Excel that you have. Column IV, which is the 256th column, is in the versions up to Excel 2003. From Excel 2007 there are 16,384 columns and last one is column XFD.
