About the remove duplicate lines

Removing duplicate lines is a common cleanup step for email lists, keyword lists, log files, CSV columns and any other line-separated data that has been merged from several sources.

The options matter: trimming whitespace catches entries that differ only by a trailing space, and ignoring case catches “Apple” versus “apple”. The first occurrence of each item is kept, so the original order is preserved unless you choose to sort.

The list is processed entirely in your browser, so contact lists and other sensitive data never leave your device.
