Clean lists without changing their order
This remover stores the first appearance of each line and discards later matches. It is useful for email lists, keywords, tags, product codes, URLs and copied spreadsheet values.
Case-sensitive versus case-insensitive
With case-sensitive matching enabled, “Apple” and “apple” are different. Leave it disabled when capitalization should not create separate values.
What does trimming do?
Trimming removes spaces at the beginning and end of each line before comparison.
