You can format dates in a variety of ways using the Format function.
Dim formattedDate As String
formattedDate = Format(Now, "mm/dd/yyyy")
' Result: "01/14/2024" if Now = January 14, 2024Time Formatting
Similarly, time can be formatted using different time format strings.
Dim formattedTime As String
formattedTime = Format(Now, "HH:MM:SS AM/PM")
' Result: "09:30:00 PM" for exampleFormatting Numbers

Format numbers to a specific number of decimal places.
Dim formattedNumber As String
formattedNumber = Format(123.4567, "0.00")
