No option to output format in excel 2007+ .xlsx
From my online research online (I'm not an MS history expert) - "XLS and XLSX extensions represent popular Excel file formats that were introduced by Microsoft as part of its Office suite over a period of time. XLS being the oldest and widely used file type is also known to be the Excel97-2003 file format. The XLSX file format was introduced as a replacement of XLS file type with the launch of Excel 2007."
The issue is, the older format has been blocked for use now on our systems, we can't open the files.
Please advise if .xlsx format is available/on the roadmap?
