Good to know
Separate values that appear more than once from values that appear exactly once. Each repeated value appears only once in Duplicates. Both results preserve first-seen order. Surrounding whitespace is trimmed, empty values are ignored, and comparison is case-sensitive unless unchecked. Commas and line breaks separate values by default; select one value per line to retain commas within a value. Quoted CSV is not interpreted.
Example: a,b,c,d,a, produces a in Duplicates, and b, c and d on separate lines in Non-duplicates.
