Mitchellt,

Welcome to the forum!
Your post is rather vague, but sounds doable. My first reaction is to use an array-entered (Ctrl+Shift+Enter) Index/Min/If formula. Hard to give you any specifics though. If that suggestion is enough to get you started, then awesome! However, if you would like additional help, then:

To best describe or illustrate your problem you would be better off attaching a dummy workbook, the workbook should contain the same structure and some dummy data of the same type as the type you have in your real workbook - so, if a cell contains numbers & letters in this format abc-123 then that should be reflected in the dummy workbook.

If needed supply a before and after sheet in the workbook so the person helping you can see what you are trying to achieve.
