How to remove duplicate lines
- Paste or open your list, one item per line.
- Choose whether to ignore case, trim spaces or sort.
- Copy or download the cleaned list.
Keeps your order
The first time a line appears it is kept, later copies are removed, and the order of the list is unchanged unless you choose to sort it.
Near duplicates
Turn on Ignore case to treat “Apple” and “apple” as the same line, and Trim spaces to ignore stray spaces at the ends of lines.
