Free Remove Duplicate Lines Tool Online - Easy and quick

Use our Remove Duplicate Lines tool to find unique lines in a plain text document and delete the copies to clean up your text. This tool can be useful to prevent repeating content in a list.

There are 2 useful options for your processing:

• Trim: When is enabled, leading and trailing spaces will be removed from each line.
• Case Sensitive Match: When is enabled, duplicates will be removed only if they match the letter case of the first occurrence. Disable it to perform a case insensitive (match case off) search.
