Office 2007 XLSX Support

hi,

I am looking for a solution that can help me in some standard way to support xlsx support to my ECC6 EHP 4 System.

I want if alv is exported ( any alv report program) in excel it should generate xlsx file Office 2007 standard xlsx file to save.

I am also looking of any class / object / functions that I can use to generate xlsx file from my custom program and send as email or do a GUI_Download.

I know I cannot ask too many questions on single thread, but my requirement is to have a standard solution that supports 2007 office excel file format in download/ upload by default.

I found an OSS not also that refer to same requirement but I want you advice that does it solve my purpose fully.

OSS note: 1286768

Thanks
