How to remove duplicate lines

  1. Paste your list or open a text file.
  2. Choose exact matching or ignoring upper and lower case.
  3. Copy or download the cleaned list; the number of removed lines is shown.

Good to know

  • Spaces at the start and end of lines are trimmed first, so "apple" and "apple " count as the same.
  • The order of the remaining lines doesn't change, unless you also choose to sort.
