Use Word Mail Merge with an Excel Data Source

Connect your Word document template to an Excel spreadsheet to automatically populate personalized data fields for each recipient.

In Microsoft Word, the equivalent of string interpolation is called 'Mail Merge'. This feature allows you to use a static template and dynamically insert variables (merge fields) fetched from a database or spreadsheet.

Prepare your template and open the Mailings tab

Open your certificate or letter template in Microsoft Word. Navigate to the 'Mailings' tab on the top ribbon and click 'Start Mail Merge' to choose your document format (Letters, Labels, etc.).

Select the Excel data source

Click 'Select Recipients' in the Mailings tab, choose 'Use an Existing List', and browse your computer to select the Excel spreadsheet containing your recipient data. Click 'OK' to link the file.

Insert merge fields

Place your text cursor in the document exactly where you want the personalized data to appear. Click 'Insert Merge Field' and select the corresponding column header (e.g., 'Name' or 'Score') from your Excel file.

Preview results and finish merging

Click 'Preview Results' on the ribbon to see how the data populates the template. Use the arrow buttons to flip through different recipients. Finally, click 'Finish & Merge' to either print the documents or select 'Edit Individual Documents' to generate a new Word file containing all the personalized pages.

Frequently Asked Questions

Can I filter out certain recipients from my Excel list during the Mail Merge?

Yes. After linking your data source, click 'Edit Recipient List' in the Mailings tab. A window will pop up where you can uncheck specific rows or use the filter option to include only recipients who meet certain criteria (e.g., only those with a passing score).

Why do my Excel dates look wrong or format differently after merging into Word?

Word often uses its default formatting rather than Excel's display formatting. To fix this, you can press Alt+F9 to view field codes and add a date format switch (e.g., \@ "MMMM d, yyyy"), or you can format the date column as 'Text' in your Excel spreadsheet before doing the merge.

Can I use Mail Merge to send personalized emails instead of printing documents?

Yes. If you have an email client configured (like Outlook), you can click 'Finish & Merge' and select 'Merge to E-mail'. You will need an email address column in your data source to route the personalized messages to the correct recipients.
