Using the Microsoft Excel 2007 or Later Convert Command

You can also convert XLS workbooks to the new Microsoft Excel 2007 or later formats using the Convert command under the Office button in Microsoft Excel 2007 or later. Crystal Ball data is converted to the current format as soon as the workbook is saved.

The Convert command, however, has a side effect of removing the older XLS file in the process. Oracle recommends that you use the Save As command to maintain a backup copy of the XLS file.
