Common questions

Are lines with different spaces treated as duplicates?

Trimming removes leading and trailing whitespace before deduplication when enabled. Internal spaces and letter case remain significant.

Does cleaning overwrite my input?

No. The input stays unchanged while the cleaned version appears in the result area.
