Duplicate Line Remover FAQs

Everything about removing repeated lines and text.

How do I remove duplicates from a list?

Paste the list into the box with one item per line, then click Remove Duplicates. That's the fastest way to remove duplicates from list exports, no formulas needed. Tick Case-insensitive and Trim whitespace if your list mixes capitals or has stray spaces.

How to remove duplicates in Excel or Google Sheets?

In Excel, select the column, then go to Data and click Remove Duplicates. In Google Sheets, go to Data, then Data cleanup, then Remove duplicates. For lists that aren't in a spreadsheet, paste them here and skip the menus.

How does Notepad++ remove duplicate lines?

Go to Edit, then Line Operations, then Remove Duplicate Lines. The "Remove Consecutive Duplicate Lines" option only catches repeats that sit next to each other. Plain Windows Notepad has no such option, so if you searched for a notepad remove duplicate lines trick, paste the text here instead and get the same result with no install.

Can I remove duplicate words instead of lines?

The tool compares whole lines. To remove duplicate words, put each word on its own line first (replace spaces with line breaks), then run it. The same trick lets you remove duplicates from string data such as comma-separated tags: one value per line, then remove duplicate text in one click.

Is the comparison case-sensitive?

Yes, by default. "Apple" and "apple" count as different lines. Turn on Case-insensitive to treat them as the same. Turn on Trim whitespace to ignore spaces at the start or end of lines.

Can I find duplicates online without deleting them?

This tool removes duplicates rather than listing them. To check duplicate online counts, compare the number of lines before and after you click Remove Duplicates. The difference is how many repeats were in your list. A dedicated duplicate finder is useful when you need to review each match.

Which copy does it keep?

With Preserve original order on, each line stays in the position where it first appeared, and later repeats are removed. Your list keeps its sequence, minus the duplicates.

Is it free to delete duplicates online here?

Yes. You can delete duplicates online for free, with no signup and no install. Use it to delete duplicate entries as often as you need.
