I'm using Microsoft Office 2003. I have installed 'Microsoft Office Compatibility Pack for Word, Excel, Powerpoint 2007' to support new xml based formats (.docx, .xlsx, .pptx).
Now given that I have installed Compatibility pack, can I create or open a Microsoft Excel 2007 file (.xlsx) having more than 256 columns in Excel 2003? If no, then how can I achieve the same.
My observation: When I open a .xlsx file in Excel 2003 with compatibility, I can't see more than 256 columns (till Column IV).
