Frequently asked questions
Which copy of a duplicate line is kept?
The first occurrence is kept and later repeats are removed, so your original order is preserved (unless you choose to sort).
Can it ignore differences in capitals or spaces?
Yes — untick “Case sensitive” to treat Apple and apple as the same, and tick “Trim spaces” to ignore spaces at the start and end of lines.
