The best way that I have found is to use the Numbers File menu > Export option to export the Numbers spreadsheet to Excel format and then use Avery Design and Print Online. https://www.avery.com/software/design-and-print/

It is free, very good and will import the spreadsheet. For me it is a much better option than using Pages/Numbers or Word/Excel.
