xls template compatibilty error

Summary:

Hi Team,

I am currently using an Excel template in the Microsoft Excel 97-2003 format, which has been working well in production. However, I need to implement a change. After downloading the template to local and opening it, I clicked "Save" without making any modifications.

I received a notification stating: "The following features in this workbook are not supported by earlier versions of Excel. These features may be lost or degraded when you save this workbook in the currently selected file format. Click Continue to save the workbook anyway. To keep all the features, click Cancel and then save the file in one of the new file formats."
