The use of a native Microsoft Excel format means that the spreadsheets are smaller and more usable. Because the new Office Open XML format is a recognized industry standard supported by ECMA International, the new format provides the added benefit of an open, documented integration format that extends an open systems solution.
The new format appears in the run report user interface. Users of Microsoft Excel XP and Microsoft Excel 2003 must install the Microsoft Office Compatibility Pack, which provides file open and save capabilities for the new format.
