Change font and size in database field

Question

I'm trying to mailmerge from word referencing to excel as database. However, I'm not exactly sure how I can change the font and the size of the field. e.g. I would like to change the font of [Person First Name] to font Arial with size 8. Kindly advice.

{DATABASE \d "{FILENAME \p}/../personnel.xlsx" \s " SELECT [Person First Name], [Person Last Name], [ID], [Title] FROM [Sheet1$] WHERE [ID] = {MERGEFIELD ID} ORDER BY [Title] " \l "15" \b "49" \h}
