Frequently Asked Questions
Can I apply multiple operations at once?
Yes. Each operation (trim, remove blanks, sort, etc.) is an independent toggle. Enable as many as needed and they are applied in order.
Does 'deduplicate' preserve original order?
Yes. The first occurrence of a duplicate line is kept; subsequent duplicates are removed. Order is preserved unless you also enable 'sort'.
What does 'collapse spaces' do?
It replaces any sequence of two or more consecutive spaces within a line with a single space, while preserving newlines.
