Mail merge troubles

[FeliciaWPM]

I didn't think I was THIS much of a newbie, but I am trying to create a simple mail merge for labels from Excel to Word. When I select (from Word) the Excel document, I get an error message saying "Missing table header." I have tried to figure out how to correct that in Excel, but am completely stymied because I really don't know how to create a table for labels. I have used multiple help articles to no avail.

I have tried to figure out how to correct that in Excel, but am completely stymied because I really don't know how to create a table for labels.

A table for labels would be created exactly as other Excel tables are, just with its own headings. So here's a link describing how to create tables. If that doesn't help, if I am misunderstanding your situation,  please come back with a more complete description of what you have done, ideally including a link to the actual spreadsheet on OneDrive or GoogleDrive.
