Step 3: Enable "Use an existing list", [Browse ... ] to find the directory containing the data file, check "All data sources" or "Excel", choose the right Excel file and open it (Sheet1$).
Step 4: write the first label (text, logo and fields of the database by clicking on [Other ]), format the text,set the layout the label (alignment, spacing) and click on the [Update all labels] button.
Step 5: check if result is consistent with what you wanted [Preview your labels] and possibly use [ Edit recipient list ... ]
