FAQ
Does it change the order of my list?
No. Unique lines stay in their original order. Use the Sort Lines tool if you also want them sorted.
What does “keep last” do?
When a line repeats, the copy kept is the final one, so it appears where the item was last listed instead of where it first appeared.
