What does Remove Duplicate Lines do?
Duplicate lines are common in keyword exports, copied logs, merged notes, and assembled lists from multiple sources. They create noise, inflate list size, and often make the next processing step harder than it should be.
This tool removes repeated lines while preserving the first occurrence, which is useful when you need a cleaner master list without manually reviewing every entry.
