Why Remove Duplicate Lines?

Duplicate data is a common problem when merging lists from different sources. Cleaning this data manually is time-consuming and prone to error.

Email Marketing: Sending the same email to the same person twice looks unprofessional and can mark you as spam.
SEO Keywords: When doing keyword research, you often get overlapping lists. Use this tool to find the unique terms.
Database Management: Clean up CSV data before importing it into SQL or Excel.

Option	What it does
Case Sensitive	If unchecked (default), “Apple” and “apple” are treated as duplicates. If checked, they are kept as unique.
Trim Whitespace	Removes invisible spaces at the start/end of lines (e.g., ” word ” becomes “word”).

Verify your cleaned list to ensure emails are real.
