First click on the System Tools Menu then choose Copy To Spreadsheet. That will bring up a menu that gives you the following file types for exporting to:

WKS (LOTUS 123)
DIF (VISICALC OR SYMPHONY)
SYLK (MICROSOFT MULTIPLAN)
SDF (SYSTEM DATA FORMAT)
XLS (MICROSOFT EXCEL)

Select the XLS (Microsoft Excel) option.

You will then have a menu pop up that lets you choose which data file you want to export. Choose the one you want to export to your selected file type. You will then be prompted for the file name for the new exported file. Enter the file name you would like and press enter.
File name can only be 8 characters long.
Example: Excelexp.

The new file is saved to your BPA directory folder with the appropriate extension for the type of file you choose to export to.

Example: If you chose Excel and entered the file name of Excelexp then the file in your BPA folder would be Excelexp.xls.
