When to use Remove Duplicate Lines
Remove repeated entries in a line-based list while retaining the first occurrence and original order.
Practical example
apple, banana, apple on three separate lines becomes apple followed by banana.
Are differently capitalized or padded lines duplicates?
No. Comparison is exact: Apple, apple, and apple followed by a space are different. Trim lines or convert case first if you want those differences removed.
