Duplicate Line Remover
Paste a list with repeated entries and get back one copy of each. The first occurrence of every line is kept and the original order is preserved, so a sorted list stays sorted and a deliberately ordered one is not scrambled.

What the Duplicate Line Remover does
Alongside the cleaned text you get a count: how many lines went in, how many unique ones came out, and how many duplicates were removed. That last number is often the point — it tells you how much overlap two merged exports actually had.
How it works
Using the Duplicate Line Remover
- 1Paste your list, one item per line.
- 2Each line is compared against the ones already seen.
- 3The first occurrence of a line is kept; later identical lines are dropped.
- 4Original ordering is preserved rather than re-sorted.
- 5Copy the cleaned list, and check the counts to see how many duplicates there were.
