Multi-Level Sort Order

Sort By:

Then By:

Can I sort by multiple columns at once?

Yes. You can add multiple sort levels (e.g. Primary Sort by Department ascending, then Secondary Sort by Salary descending).

Does the sorter handle natural numbers correctly?

Yes. Natural numeric sorting ensures numbers like 2, 9, 10, 100 sort in true numerical order rather than alphabetical string order.

Are my files sent to any remote server?

No. All sorting algorithms run directly inside your browser's local memory with zero external requests.
