Sorting two columns

your example looks like you have four columns, one with Bill, one with 55, one with Bob and one with 66.
I'm assuming you have it in two columns so if you have Bill in cell A2 and 55 in cell B2 and Bob in cell A3 and 66 in cell B3 etc. then apply a filter to the columns then use the sort descending for column B and column A will follow. If you don't want the filter to remain then after the sort is complete then remove the filter.

If you want the sort to be done in 2 extra columns, you could use LARGE() for the number columns, then use INDEX/MATCH to pull in the relevant name. Could there be duplicate numbers in your list, and if so, how would you want that handled?
If this is what you want, and dont know how to do it, let me know and we cam walk you through it.

If, on the other hand, you want the list sorted in place, you can use the SORT option on the menu bar

@ Sambo, I think the 2nd list is how the OP wants the data to look afterwards?

Then use the process I described in the 2nd paragraph of post#2. Apply a filter to the (likely) 1st row then click the down arrow and at the top of the dropdown box you'll see a down arrow and A:Z for ascending order and below that an up arrow and Z:A for descending order sort. Use Z:A and both columns should sort the way you want. You can also use the sort function on the home tab. Either should get you what you want.
