DataGrid DataProvider Excel export in iPad

[Deepak MS <me...@gmail.com>]

Hello,
We are trying to export data to excel and open the excel in iPad. We were
able to give a 'Open with..' option, but when user selects 'Excel' app to
open the document, it needs xlsx format and not xls. We used AS3XLS and it
doesn't have xlsx support.

Came across this link, which supports xlsx but there isn't usage example.
It has another library which is FZip, which isn't there in the source:
https://github.com/flexmonster/fl2xls/tree/master/com/flexmonster/xls


Has anybody used that library or any other library which can give xlsx
exported file?
