Which separators are supported?

Commas, semicolons and any whitespace (spaces, tabs, line breaks) split items. Leading and trailing spaces are trimmed automatically.

Is the calculation case-sensitive?

Yes. Apple and apple are treated as different items, and results keep the order in which items first appear.
