What Remove Duplicate Lines does — and what it doesn’t
Clean repeated entries from lists, exports, keyword sets and copied text.
Duplicates depend on what you consider “the same”
Capitalisation, surrounding spaces and punctuation can make two lines technically different even when they look equivalent to a person. Normalise first if those differences shouldn’t count.
With Remove Duplicate Lines, the main limit is this — text tools work on characters and separators; they don't understand the intent behind every sentence or dataset. Trim accidental spaces before deduplicating.
When Remove Duplicate Lines isn’t the right endpoint
Normalize spacing or case first when visually equivalent lines should collapse into one.
