The link I sent you is what you need. You do not print them directly from excel. This has never been an option. If you are doing it any other way you are not going to get very far. This is an excerpt from Microsoft on the matter: "If you want to send a mass mailing to an address list that you maintain in a Microsoft Office Excel worksheet, you can use a Microsoft Office Word mail merge. The mail merge process creates a sheet of mailing labels that you can print, and each label on the sheet contains an address from the list."
This is the link I sent you that will create the sheet so that you can do a mail merge.https://support.office.com/en-us/article/Create-and-print-labels-using-mail-merge-276a2cd1-74d2-43d0-ab5a-b90460358ad5?ui=en-US&rs=en-US&ad=US
If you were on a PC there is a Avery Label Wizard that walks you through the same process assisted, but if you follow the instructions in the guide you will get what you need done. The issue has nothing to do with this "text converter" you are looking for. Please follow the guide to resolve your issue.
