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. The same idea underpins a lot of everyday Excel work, so the few minutes spent getting it right here pay back across every sheet you build afterwards. Treat it as a pattern, not a one-off, and it stops being something you look up and starts being something you reach for. The difference between a quick fix and a sheet you can trust is the extra minute you spend validating “convert an excel spreadsheet to mailing labels”. Start on a copy or a tiny sample, keep the affected sheet visible, and compare the result with the outcome you expected before you touch the real workbook. 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. The point is a data step that keeps your analysis trustworthy, but the practical win is that someone else can open the file and understand what happened without asking you.
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. If this is something you do often, add the command to the Quick Access Toolbar (right-click it on the ribbon and choose Add to Quick Access Toolbar) or learn its shortcut, so next time it is one click instead of a hunt through the menus.
In Google Sheets
This is a command rather than a formula, so there is no syntax to carry over. Google Sheets arranges its commands in menus across the top instead of a ribbon, names some of them differently and does not have every Excel command — look for the equivalent in the Sheets menus or its help before assuming the steps match. Nothing on this page is behind a login or a download: the exact answer is at the top, and the detail below it is there for when you need it. That is the whole promise here — the answer first, and just enough context to make it stick. Treat “convert an excel spreadsheet to mailing labels” as a routine rather than a one-off. Once you know which setting or command controls it, the same few steps handle every workbook where it comes up in Excel, and you can explain them to a colleague in a sentence.
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.
