In Excel: prepare one header row in Excel, save the workbook, then in Word use Mailings ▸ Select Recipients ▸ Use an Existing List and insert merge fields from that sheet.
Put one clean header row at the top of the Excel list.
Remove blank rows, merged cells and totals from the recipient data.
Save the workbook, then open Word and start the mail merge from the Mailings tab.
Select the Excel workbook as the recipient list, insert fields, preview results and finish the merge.
What this does
Mail merge uses Excel as the recipient database and Word as the document template. Each Excel row becomes one letter, label, envelope or email; each column header becomes a merge field such as FirstName, Company or AmountDue. Clean headers and consistent data types matter because Word reads the first row as field names. Most people learn this as a sequence of clicks and forget it by next week; learning it as a pattern instead is what lets you apply it to the next, slightly different version of the problem without starting from scratch. That is the difference this page is trying to make. For “mail merge address labels from excel”, the reliable version is a short checking loop, not just the first command that appears to work. Run it on a deliberately small range first, watch how the affected cells change, and only then apply the same setup to the full sheet. When this is a ribbon command, the selection matters more than the button: confirm the range, apply the command, then spot-check the output before saving. That is what makes a text operation that turns messy entries into clean, usable data useful in real work: repeatable, auditable, and not dependent on memory or luck.
A worked example
A sheet named Customers has headers FirstName, LastName, Address and Balance. Save and close the workbook, open Word, choose Mailings ▸ Start Mail Merge ▸ Letters, then Select Recipients ▸ Use an Existing List and pick Customers. Insert FirstName and Balance fields; preview shows each row merged into the letter. Mail merge is the practical bridge between spreadsheet lists and personalized documents: invoices, notices, labels, certificates and any message that repeats with row-specific details. A practical tip before you scale it up: build it once on a small block of test data, confirm the number against the tool on this page, and only then point it at your real sheet. That one habit catches almost every mistake while it is still cheap to fix, long before a wrong figure reaches a report or a colleague.
In Google Sheets
Google Sheets handles this almost identically to Excel. The formula syntax above is the same, and the menu lives under a slightly different label rather than a ribbon tab. Use the platform toggle at the top of the page to switch every keyboard shortcut between Windows and Mac, and expect at most cosmetic differences in naming. Nothing on this page is behind a login: the tool runs entirely in your browser, the formula is shown in full with one-click copy, and the steps work the same on Windows and Mac. That is the whole promise here — the exact answer, a way to prove it on your own numbers, and just enough context to make it stick. Here is the takeaway for “mail merge address labels from excel”: copy the answer if you are busy, but if you have a spare few minutes, rebuild the example in Excel yourself with the tool above open beside it. That single pass — type it, run it, watch the result move when you change an input — is what turns a formula you found into a technique you trust. Keep your inputs labelled and referenced, never hard-coded, and the same sheet stays correct and auditable as it grows. Done that way, you will not need to look this up again, and you will be the person others ask.
Common mistakes
- Using merged cells or multi-row headers, which Word cannot treat as clean field names.
- Leaving the workbook unsaved or open in a way that prevents Word from reading the latest data.
- Formatting ZIP codes or IDs as numbers, which can drop leading zeros during merge.
- Forgetting to preview several records before printing hundreds of letters or labels.
Frequently asked questions
Can Word mail merge directly from Excel?
Yes. Word reads a worksheet or named range from an Excel workbook as the recipient list.
Why are leading zeros missing?
Excel stored the values as numbers. Store ZIP codes and IDs as text before merging.
Can I filter recipients?
Yes. In Word, use Edit Recipient List to filter and sort the Excel rows before finishing.
