How to get xlsx output from XML Publisher in Oracle Apps R12 instead of xls

Hi,

I am trying to get outputs in multiple worksheets from XML Publisher in Oracle Apps R12.

While designing the template, I am defining different sections in different pages with a page break.

On desktop previewer for BI Publisher, there are two different types of Excel Previews Available:

1) Excel

2) Excel2000

While previewing my rtf template with Excel option, I am getting the desired output, i.e. different sections(defined with page break) in different worksheets.

But on previewing with Excel2000, I am getting all the sections on one worksheet only.

While running the concurrent program, I am getting the same output as Excel2000 previewer option.
