Hi All,

I am trying to change my excel export format from .xls to .xlsx but till now
I dont have any luck for this. I also tried changing content type and
extension to .xlsx with no luck.

Also when opening with .xls in Excel 2007 it gives me format error. I am
sending plain HTML with content type changed to achive this.

I want this functionality to be migrated to .xlsx format with minor changes
in code.

Please help me out on this.
