FAQ
Does the order of lines change?
No. The original order of lines is preserved. Only the duplicate entries (second and subsequent occurrences) are removed.
What does case-sensitive comparison mean?
With case-sensitive on, 'Apple' and 'apple' are treated as different values and both kept. With case-sensitive off, they are treated as the same and only the first occurrence is kept.
