Many businesses have transitioned from Excel 2003 to Excel 2007 (and beyond). The question then becomes what to do with those old Excel file formats? Documents created in Excel 2003 are saved in an .xls format. Documents created in Excel 2007 and 2010 are saved in a .xlsx format. This is no subtle difference. Files saved as .xlsx cannot be opened in Excel 2003. On the other side files saved as .xls can be opened in Excel 2007 but have limited functionality. One solution to this problem is to convert old files into the latest Excel format. This would require going to each file and saving it in the new format. In many organizations this can be hundreds of files. A quicker approach would be to use VBA (Visual Basic for Applications) a programming language to make these file changes in seconds.
