Excel thinks that some or all of the cells in the column you are trying to sort are merged. Perhaps you set up a heading with merged cells? To get the sort to work, you can either split all of the cells in the column or merge all of the cells in the column. <p> However, to echo [halley]'s point, perhaps you should consider taking a different approach to generating your files. Have you looked into [cpan://Spreadsheet::WriteExcel]?
