Remove Duplicate Lines Online

Drop repeated lines in the browser. Ignore case, trim spaces, keep the first or last copy, sort, and download the unique list.

One copy of each line.

Email lists, ids, and log excerpts repeat themselves. Spoold's duplicate line remover compares each line in the browser and gives you the unique list to copy or download.

Which copy stays

  • Keep first leaves the earliest line and drops later matches.
  • Keep last leaves the latest line.
  • Turn case sensitivity off when Ada and ada should match.
  • Sort A–Z after the duplicates are gone, or leave the original order.

Whole lines only. To dedupe a spreadsheet by one column, use CSV Operations.
