find the names

[kamakshi]

iam finding the last name and first but i need to see first letter firstname should be upper case and last name first letter should be upper case
for example
hari sunder it should give the result of Hari Sunder

Sub macro1()
 Dim firstName As String
    Dim lastName As String
    Dim n As Integer
    Dim rowNum As Integer
    Dim colNum As Integer
    rowNum = 1
    colNum = 1
    
    While Cells(rowNum, colNum).Value <> ""
        n = InStr(1, Cells(rowNum, colNum).Value, ",")
        lastName = Left(Cells(rowNum, colNum).Value, n - 1)
        firstName = Right(Cells(rowNum, colNum).Value, Len(Cells(rowNum, colNum).Value) - n - 1)
        Cells(rowNum, colNum + 1).Value = firstName
        Cells(rowNum, colNum + 2).Value = lastName
        rowNum = rowNum + 1
    Wend
End Sub
