Mail Merge Dates Issue

Try referring this:

1. Check Excel Date Formatting:
   • Ensure that the date column in your Excel sheet is formatted as a date. Even if it appears as a date, Excel might still treat it as a number.
2. Use Dynamic Data Exchange (DDE):
   • Using DDE can help maintain the formatting from Excel to Word. To enable DDE:
     1. In Word, go to File > Options > Advanced.
     2. Scroll down to the General section and check the box for Confirm file format conversion on open.
     3. Start the Mail Merge process again. When selecting your Excel file, a dialog box will appear. Choose MS Excel Worksheets via DDE.
3. Apply a Date Format Switch in Word:
   • You can add a switch to the merge field to format the date correctly:
     1. In your Word document, press Alt + F9 to display the field codes.
     2. Locate the date merge field, which will look something like { MERGEFIELD YourDateField }.
     3. Modify it to include a date format switch, such as { MERGEFIELD YourDateField \@ "dd MMMM yyyy" }.
     4. Press F9 to update the field and Alt + F9 again to toggle back to the normal view.
4. Refresh Data Source Connection:
   • Sometimes, refreshing the connection between Word and Excel can help:
     1. Go to the Mailings tab in Word.
     2. Click Select Recipients and choose Use an Existing List.
     3. Re-select your Excel file.
5. Check Regional Settings:
   • Ensure that the regional settings in both Excel and Word are consistent, as differences can cause formatting issues.
