A tough question from the MrExcel Message Board. There are 1500 rows showing products in a delimited string. Someone might have had "Cherry, Apple" yesterday and today they have "Apple, Banana, Cherry". Can you use a VBA macro to subtract Cherry Apple from Apple Banana Cherry and end up with just Banana?
Today, I end up solving this with Excel Power Query, Split by Delimiter To Rows, and then a Right Anti-Join. The best part: you can refresh the query tomorrow.
