Clean repeated rows without a spreadsheet
Duplicate lines show up in copied emails, keyword lists, CSV columns, ID exports, and notes. This tool keeps the first occurrence and removes later repeats so the list stays close to the order you pasted.
Trim mode handles accidental spaces at the start or end of a row. Case-insensitive mode treats Apple and apple as the same value, and the empty-line option removes gaps when you want a compact list.
The cleanup runs in the browser. Lists, customer snippets, keywords, or internal IDs are not uploaded to berryfy.
