Migrate from Microsoft Excel

If you try to merge from a Microsoft Excel spreadsheet, you will note that there is no Extensions option on the menu bar. To run the Avery Label Merge add-on, you first need to convert your Excel spreadsheet to Google Sheets format.

From your Excel spreadsheet, click File > Save as Google Sheets. This will create and open a copy of your file in Google Sheets format, from which you can run the Avery Label Merge add-on as normal.

NOTE: If you are merging from Google Docs, the add-on will automatically convert your Microsoft Excel source spreadsheet into Google Sheets format; there is no need to do this manually prior to merging. Your Excel spreadsheet will appear in the Select a Spreadsheet File dialog box (see screenshot below).

During the label merge process, your original Excel spreadsheet will be preserved and a copy of your spreadsheet will be created automatically in Google Sheets format.
