Bulk rename files using names in a text file or spreadsheet

[willhubs]

I have a folder with almost 2000 files in it, all in alphabetical order and I have a text list what I want them all to be named. It would be nice to be able to select all of the files, verify they are in order, and replace them with the names from the names.txt text list.

Or a spreadsheet that has the existing name in the first column, and the replacement name in the second column.
