Deduplicate lists without a spreadsheet
Merged two exports? Combined mailing lists? Paste the result and click Remove duplicates — each unique line is kept once, in its original position. The sort, trim, and shuffle buttons are right there for any follow-up cleanup.
Frequently asked questions
Does deduplication keep my original order?
Yes — the first occurrence of each line stays where it was; later repeats are removed. Sort afterwards if you want alphabetical order too.
Are “Apple” and “apple” treated as duplicates?
With “Ignore case” checked (the default), yes. Uncheck it for exact, case-sensitive matching.
How do I see how many duplicates were removed?
After running, the tool shows the before → after line count, e.g. “250 → 187 lines”.
