How to Remove Duplicates
- Paste Your List: Copy your list of emails, names, URLs, or data from Excel or Word, and paste it into the left-hand text box. Ensure that each item is on its own separate line.
- Choose Options: Check the boxes to customize how the tool behaves. You can automatically sort the final list alphabetically (A-Z), delete empty blank lines, and trim away accidental spaces.
- Clean List: Click the red “Remove Duplicates” button.
- Copy Result: A green banner will tell you exactly how many duplicates were found and deleted. Click “Copy List” to copy the perfectly cleaned data back to your clipboard.
Advanced Options Explained
- Trim Whitespace: If you accidentally have ” Apple ” on one line and “Apple” on the next, a computer sees them as two different words because of the invisible space! Keeping this checked removes those spaces before comparing them, ensuring the duplicate is caught.
- Case Sensitive: By default, this is turned off, meaning “HELLO” and “hello” are considered the same word, and one will be deleted. If you turn this ON, the tool will treat “HELLO” and “hello” as two completely unique lines and keep both.
