Locale compare handles most name lists. Numeric sort uses locale numeric collation so item2 sorts before item10. Length sort is useful for prioritising short titles or finding outliers. Pick the mode that matches how humans will scan the result.
Sorting with Math.random comparators skews permutations — some orders are far more likely than others. Shuffle here uses Fisher–Yates with crypto.getRandomValues when available, giving each ordering a fair chance for raffles, test data order, or classroom name picking.
This is not a spreadsheet: no multi-column sort, no stable sort keys, no seeded random for reproducible tests. Numeric mode follows JavaScript locale rules, not natural parsing of values like 10kg versus 10 kg.
That is the promise behind every tool here. Files are read in your browser tab, processed there, and discarded when you close it — never uploaded to our servers.
