Online Duplicate Remover

What is a Duplicate Remover?

The Duplicate Remover is a free online list tool that can identify and remove all duplicate entries in the list, keeping only one instance of each duplicate entry, making data deduplication more efficient.

In addition, it can also be used to remove all empty lines in the list and trim leading and trailing whitespace characters, such as spaces or tabs, from each line in the list.

How to Remove Duplicate List Entries?

Paste the list text in the input box, or click the button to select a text file. You can also drag and drop the text file directly onto the page, and the tool will automatically read and load the text data from the file.

You can choose whether to remove all empty lines in the list or to remove all whitespace characters on both sides of the list entries according to your needs. Both of these options are automatically selected by default, but you can also deselect them.

Click the 'Remove Duplicates' button, and the tool will remove all redundant duplicate entries from the list, leaving only one instance of each duplicate data.
