Frequently asked questions
What is the difference between Lines and Words mode?
Lines mode removes duplicate rows from a list if the same line appears more than once, all but the first occurrence are removed. Words mode removes duplicate words across the entire text regardless of line breaks.
Does case matter when detecting duplicates?
By default no "Apple" and "apple" are treated as the same. Toggle Case Sensitive on if you need them treated differently.
