About Duplicate Line Remover
The duplicate line remover keeps the first occurrence of each unique line and discards any repetitions. This is essential when cleaning exported data, email lists, keyword lists, or any CSV/TSV data that may contain repeated entries.
Enable Ignore case to treat "Apple" and "apple" as duplicates. Enable Trim whitespace to normalize lines before comparison, so " hello " and "hello" are considered the same line.
