About the Remove Duplicate Lines
Cleaning a list often means stripping repeats. This tool removes duplicate lines while keeping the first occurrence in its original position, unlike a sort that reorders everything.
Toggle ignore-case to treat Apple and apple as the same line. Processing happens entirely in your browser.
