Naive sorting compares character by character: '1' comes before '2', so '10' beats '2' regardless of value. Natural (numeric) ordering — on by default here — compares digit runs as numbers, producing the order humans expect: item 2, item 10, item 100.

It sorts entries as if a leading 'The', 'A', or 'An' weren't there, so 'The Godfather' files under G and 'A Clockwork Orange' under C — the convention used by libraries, film lists, and record collections. The article stays visible in the output; it's only ignored for ordering.

Leave it off for almost everything: 'apple' and 'Apple' will sort together naturally. Turn it on only when capitalization is meaningful in your data — code identifiers, for instance — where you want a deterministic order between otherwise-identical entries.

Yes — switch on comma mode and the tool splits on commas, trims the whitespace, sorts, and rejoins with commas. Handy for tag lists, keyword sets, and single CSV rows. For full multi-column CSV files, a spreadsheet is the right tool; this is for the quick one-dimensional cases.
