Remove Duplicate Lines

Use this text 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.

When “Trim” is enabled, leading and trailing spaces will be removed from each line.

When “Case Sensitive” 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.

• Remove Spaces - Remove leading and trailing white spaces (spaces and tabs), and convert multiple spaces into a single space.
• Remove Empty Lines - Get rid of all the lines in a text that only consist of whitespace (spaces or tabs).
