Printing Labels using Specific Fields with Contacts

What works for me:

Open both Contacts app and a Numbers spreadsheet. Select all contacts or the ones that you want to use and then drag them to the Numbers spreadsheet (only works with Numbers, not Word or Excel). Edit the spreadsheet as needed, deleting unneeded columns and adding columns as needed. My spreadsheet it designed with a column for "The Smith Family" for example that is blank for contacts where I want to use "John Smith" instead and then a column that automatically selects which to use based on whether or not the column is blank. You can do that or not depending on your needs.

I then export the Numbers spreadsheet to Excel format.

Then I use Avery Design & Print online. It is very flexible, easier to use than either Word or Pages, and easily merges the Excel spreadsheet. Also, very small learning curve. See: https://www.avery.com/software/design-and-print/

Is this any help? Print mailing labels, envelopes and contact lists in Contacts on Mac
