Duplicate Remover
Your list
How to use this calculator?
1. Paste your list with duplicates (one item per line)
2. Choose whether to ignore case
3. Duplicates are removed automatically
4. Copy the cleaned list
Quick answer
How do you remove duplicates from a list?
Paste your list with one item per line: the tool keeps the first occurrence of each line, removes repeats and skips empty lines. Tick "Ignore case" so that "Paris" and "paris" count as the same item. Example: the list apple, pear, Apple, apple, kiwi becomes apple, pear, Apple, kiwi, or apple, pear, kiwi when case is ignored.
About the Duplicate Remover
What is it?
The duplicate remover instantly cleans your lists by eliminating all duplicate entries, with case sensitivity options.
Why use it?
Duplicate lists (emails, names, keywords, URLs...) cause duplicate sends in email marketing, skewed analytics data and unnecessary work. This tool cleans with one click.
How does it work?
Paste your list into the text area (one value per line). Choose whether comparison should be case-sensitive or not, then click remove duplicates. The clean result appears immediately.
