Frequently Asked Questions

Do numbers sort numerically?

Yes — numeric columns sort by value (2 before 10), everything else alphabetically. ISO dates (YYYY-MM-DD) order chronologically as a side effect of text order.

How large a file sorts?

Tens of thousands of rows sort instantly locally. Past ~100k rows, split by month first for smoother handling.

Can I sort by multiple columns?

Single-column per pass: sort the secondary key first, then the primary — stable sorting preserves the earlier order within ties.

Does my spreadsheet leave the browser?

No — sorting runs locally in your browser. Data never leaves your device.

How are mixed numbers and text sorted?

Per pair: both-parse-as-numbers compares numerically, otherwise localeCompare text. A stray N/A in an age column sorts textually against numbers; the default age demo orders Jane 28, Alice 31, John 35, Bob 42.
