Frequently Asked Questions
Does removing duplicates sort or scramble my list?
No. Unlike tools that sort lines alphabetically to find duplicates, this tool uses a hash set to keep the first occurrence of each line in its exact original position.
What does 'Ignore Whitespace' do?
When enabled, lines with accidental trailing or leading spaces (e.g. `'item '` and `'item'`) are treated as identical and trimmed cleanly in the output.
