Did it let you enter data and calculate? Will try it in a mo.I downloaded the .xls and put it into "Online XLS XLSX Excel Viewer" at https://www.onlinedocumentviewer.com/Blog/online-xls-xlsx-excel-viewer.aspx
It shows up.
Viewing isn't a problem as Libra office lets me view the spreadsheet.
It's getting those pesky macros to work.
