Cleaning up data shouldn’t take hours. Whether you are managing an email newsletter, organizing a guest list, or cleaning up database entries, having duplicate items is a hassle. Our tool eliminates repeated lines instantly.
Simply paste your list, and our algorithm will scan for duplicates, trim extra spaces, and give you a perfectly clean, unique list in milliseconds. No formulas, no macros, just results.
It distinguishes capitalization.
If enabled, the tool treats “Apple” and “apple” as two different items.
If disabled (default), it treats them as the same item and removes one of them.
This gives you control over how strict the cleaning process should be.
To fix invisible errors.
Often, when copying from Excel or the web, items have invisible spaces at the end (e.g., “Email ” vs “Email”).
These spaces make the computer think they are different words.
The “Trim” function deletes these spaces before comparing, ensuring a 100% accurate cleanup.

After removing duplicates, you can click “Sort A-Z” or “Sort Z-A” to alphabetize your data instantly.
