Duplicate Removal Guide

How does duplicate detection work?

The tool compares each line of text and removes exact duplicates while preserving the first occurrence of each unique line. The original order is maintained.

What's the difference between case sensitive and case insensitive?

Case sensitive treats "Apple" and "apple" as different lines. Case insensitive treats them as duplicates and removes one of them.

Are empty lines removed?

Empty lines are treated like any other line. If you have multiple empty lines, only the first one will be kept unless you want all empty lines removed.
