Hi Syed,
We recently built a sample Export to Excel component as part of Design Studio 1.2 SDK Beta version.
http://www.visualbis.com/blogs/design-studio/2013/09/17/sap-design-studio-export-to-excel-addon/
Its not available for public release yet. But I guess soon there will be more exporting options in Design Studio, including a native one from SAP.
Regards,
Aakanksha
