Remove duplicate lines from any list
A duplicate line remover is handy for cleaning email lists, keyword lists, CSV exports or any text where the same line appears more than once. This tool keeps the first occurrence of each line and removes every repeat that follows, with optional case-insensitive matching.
How it works
Paste your list, choose whether case should matter and whether to trim stray spaces, then click "Remove duplicates" to get a clean, unique list ready to copy elsewhere.
