We are going to impliment office 2010. Current reporting system using crystal report 2008 and viewing reports via web (i.e calling the .rpt files from web page). While we put the Run report, it will open the report in Crystal Report Viewer and dispaly in new web page. From Crystal report viewer user can export to various excel versions. But its not displaying the .xlsx option to export. How can i include .xlsx option also in crystal report viewer export list as one of the file option.

Will be thankful, if you can suggest a solution on this.
