2. Choose your options, such as Case sensitive, Trim spaces or Remove empty lines.

The first time a line appears it is kept, and any later copies are removed, so your list keeps its original order.

Duplicate Line Remover Tool: What to Look For

A good duplicate line remover tool should be fast, accurate and free of limits. This one compares each line exactly, lets you ignore upper and lower case, and can trim extra spaces so that "apple" and "apple " count as the same line. The result is plain text that you can paste into any editor, spreadsheet or website.

Delete Duplicate Lines Online Without Installing Anything

You can delete duplicate lines online from any phone, tablet or computer. There is no software to download and no macro to write in a text editor. If you also need strong credentials for the accounts you manage with your lists, try our Random Password Generator.

Remove Repeated Lines Online and Keep Your Data Private

When you remove repeated lines online, privacy matters, especially for email addresses and customer data. Your text is processed in your browser and is not uploaded to a server, so your lists stay on your device. You can clean as many lists as you like with no watermark, no account and no daily limit.

Why Clean Duplicate Lines?

Duplicates waste space and cause mistakes. A mailing list with repeated addresses sends the same message twice, a keyword list with repeats skews your research, and a data file with repeated rows breaks reports. Removing them first saves time later. When your data needs unique identifiers, the UUID Generator can create them for you.

Tips for better results

• Turn on Trim spaces if your list came from a spreadsheet or copied web page.
• Use Case sensitive only when "Apple" and "apple" must be treated as different lines.
• Remove empty lines to get a tight, compact list.
• Keep a copy of the original text in case you need to compare it with the cleaned version.
