A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
I not sure exactly what you mean.
I'll give it a Try.
If say you have the three heading as described.
You can index with up to three criteria at a time
Open > Data > Sort. when you open the sort window there are three columns you can sort by.
in your case there would be
Country First
Region Second
Third City.
If sorted wrong reverse the order.
