formatting problems with Excel mail merge field in a Word document, Excel data doesn't keep formatting in Word mail merge

The mail merge feature in Microsoft Word is a time-saving option for creating repetitive documents, from letters to contracts to emails to labels and more. However, you may notice a glitch that happens when you create a mail merge in Microsoft Word with Excel data. That is, the number formatting in Excel doesn’t show up correctly in the Word document. For example, a dollar amount of $1,234.00 in an Excel worksheet used as a data source may display as 1234 in a Word document. You might also see formatting issues with other numbers that are displayed as text, such as zip codes, lease or property numbers, and other identifiers.

When you see formatting problems, how can you format the Excel mail merge field to accurately display the formatted number in a Word mail merge main document? The solution to controlling the number and currency formatting of Excel data in Word is to add a numeric switch (previously called a picture switch) to the mail merge code or MERGEFIELD. Try this formatting fix on letters, emails, and other documents when Excel data does not retain its formatting in mail merge operations in Word.

For example, in this sample letter, the Amount field is a merge field from a linked recipient list created in Excel. When the results are previewed, the amount displays as 1000 without the currency formatting in the original data source. With a simple edit, the field can be changed to display the formatting you want in the document.
