About the Duplicate Line Remover
Clean repeated items from copied lists while deciding whether capitalization and surrounding whitespace should affect equality.
How comparison works
Each line receives a comparison key based on the selected case and trimming options. The original display line is retained in the output.
Example
With case sensitivity disabled, Apple and apple are treated as the same line and only the selected occurrence remains.
Notes
Blank lines are also values and can be deduplicated. Enable trimming if whitespace-only differences should not create separate items.
