If you are using Excel 2003 or earlier, 256 columns by 65 536 rows is your
limit. Type "specification limits" into Excel help, or look at
http://office.microsoft.com/en-us/ex...375451033.aspx.
Number of worksheets in a workbook is limited only by available memory. If
you want to insert a worksheet, use the command Insert/ Worksheet.

Excel 2007 increases the row & column limits to 16 384 columns by 1 048 576
rows:
