My Spreadsheet has one column with a list of Customer NameCodes.
Another column will be filled with comments that include portions of the
NameCodes or the NameCodes plus more characters.

Is there a way to have the macro identify close matches?

Simplified Sample:

A B
JohnD Sold 100 widgets to JohnDoe
Mary Smith Sold John D 100 large widgets
BenH Received from Mary 6 return items
