How to remove duplicate lines

Quick answer: To remove duplicate lines, paste your list, choose options and copy the clean list.

  1. Paste your list. One item per line: emails, keywords, names, URLs.
  2. Choose options. Ignore upper/lower case, trim spaces, drop empty lines, sort.
  3. Copy the clean list. You'll see how many duplicates were removed.

Cleaning email and keyword lists

Turn on ignore case and trim spaces so "Name@site.com " and "name@site.com" count as the same line.
