How to Make My Spreadsheet Look Like an Excel 2003 Spreadsheet

1. Complete your spreadsheet as normal and save it. This copy will be for your future use and is still in 2007 format.
2. Click on the 'Office' button in the upper left corner. This is a stylized version of the Windows logo. Many people mistake it for just a graphic, but several useful functions are hidden beneath it.
3. Click on 'Save as' and then select the option that says 'Excel 92-2003 Workbook.' Give your file a new name. The file extension of this file will be '.xls' instead of '.xlsx,' but you should give it a meaningful name to easily differentiate it from your 2007 files.
