How to use the Remove Duplicates

1

Three dedup modes

First occurrence: standard dedup — first time each line appears, it's kept. Last occurrence: keep the bottommost copy and drop earlier ones (useful when the latest copy is the most up-to-date). Only unique: keep only lines that appear exactly once — anything that appears twice or more is dropped completely.

Common uses

Clean up email lists, remove duplicate URLs, deduplicate log entries, find unique values in a CSV column. The trim option helps when entries differ only by surrounding whitespace.
