Does BOE XI3.1 or even BI 4.1 Crystal reports viewer support export format excel 2007

Hi there,

We have recently upgraded to BOE XI3.1 SP7 and we actually use the Crystal Reports Viewer (tomcat web app CrystalReports) as our web report rendering engine. I am wondering if the export format support excel 2007 (xlsx) ?

I know in SP6/7 the WebI starts to support such format and Crystal reports for VS 2010 also does. How about CR in the BOE/BI?

Thanks
