Common questions
Is comparison case-sensitive?
The tool treats lines as exact matches. "Apple" and "apple" are considered different lines.
Does row order change?
Unique lines are kept in the order they first appeared in your original list.
Can it handle thousands of lines?
Yes, for typical list sizes. Very large files may slow down depending on your device.
