What if some rows have no supplier assigned?+

Rows with a blank supplier column are grouped into a separate unassigned file.

Can I split by supplier and then by category?+

Run the supplier split first, then run the Category split on each resulting supplier file.

Does this work for files with hundreds of unique suppliers?+

Yes, though a very high number of suppliers will produce a large number of output files. The free tier handles files up to 2 MB.
