FAQ

What limitations should I know?

Full-line matching: only completely identical lines count as duplicates; case, full-width/half-width, and in-line spacing differences stay distinct.

When might it fail?

With Keep leading/trailing spaces, lines that differ only by edge spaces are not merged.

What else should I watch for?

Sorting changes only how unique results are shown, not dedupe logic or occurrence counts.
