Naturally, there will be a few different ways to do this. Instead you’d like to identify which records have duplicate entries in the list. While it would be easy to just hit the SKU column with the Remove Duplicates function, you don’t want to do that.

While the list provided to you was supposed to be duplicate free, you’re not 100% sure that it actually is. While multiple brands are okay here, we need a list that shows only unique SKU numbers. Suppose someone has given you a list like the one shown below (which you can download here if you’d like to follow along): Some time ago I got an email from Alex asking me if there was a way to identify duplicates using Power Query, but without removing non-duplicate records in the process.
