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 “mail merge in excel to word”. Start on a copy or a tiny sample, keep the affected cells visible, and compare the result with the tool above 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 text operation that turns messy entries into clean, usable data, 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. When the result is not what you expected, undo straight away rather than repairing it by hand — undo restores the sheet exactly, while manual fixes tend to leave small inconsistencies behind that surface later.
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. The aim was to get you unstuck fast and leave you a little more capable than a copy-paste would. The answer is at the top and the detail above shows why it holds — so the next time a colleague asks, you can answer without reaching for search. Here is the takeaway for “mail merge in excel to word”: follow the steps at the top, check the result on the sheet itself, and keep undo in mind while you experiment. Done once deliberately, it becomes something you do from memory in Excel rather than something you search for again.
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.
