To create the Excel workbook first select the format of the generated workbook and press the Create Workbook button. The Excel workbook will be created on the server and sent as an attachment to the browser. You will be prompted to open the generated workbook in an exernal viewer. The free Excel Viewer from Microsoft supports both the Excel 97-2003 (.xls) format and the new Excel 2007 (.xlsx) format.
