Duplicate line remover is an online text mechanic to find and remove duplicate lines of text. Lines can even be compared in a case insensitive way. Empty or blank lines can be deleted & whitespace can be trimmed. All the removed lines can be seen or checked along with their line numbers using this tool. You can also see a count of how many times a line appeared. Finally, you can sort the deduped lines in ascending or descending order.
You can easily save the pure file by naming the file in the "File Name" then hit "save as".
