How to use the remove duplicate lines
- Paste your list in the left box, one item per line.
- Choose the options: case sensitive, trim spaces, remove empty lines and sorting.
- Copy the cleaned list from the result box.
What it does
The first time a line appears it is kept, and later copies are removed. By default the comparison ignores upper and lower case, so "Apple" and "apple" count as the same line. Turn on Case sensitive to keep both.
It is useful for cleaning email lists, keyword lists, log files, URLs and any data copied from spreadsheets.
