About this tool
Duplicate lines appear in lists, CSV exports, log files, and anywhere data gets concatenated from multiple sources. Manually finding and removing them is tedious and error-prone. This tool removes exact duplicate lines while keeping the first occurrence and preserving the original order of your text. Blank lines are kept so your formatting stays intact. It works on any text, from short lists to thousands of lines.
