What is this Tool For?

The Remove Duplicate Lines tool is useful for anyone working with text data: cleaning up keyword lists, deduplicating email lists, processing log files, or removing repeated entries from any line-based data source. Instead of manually scanning and deleting duplicate lines, this tool does it instantly regardless of how many lines your data contains.

FAQ

Does case matter when removing duplicates?

By default, the comparison is case-sensitive, so "Apple" and "apple" are treated as different lines. Enable the "Case-insensitive" option to treat them as duplicates and keep only one version.
