Excel formulas with round function

See my reply in Link part of file name to Excel cell for your question about the filename.

Here is a macro:

Sub AddRound()
    Dim rng As Range
    Dim s As String
    Dim p1 As Long
    Dim p2 As Long
    Dim p3 As Long
    Application.ScreenUpdating = False
    For Each rng In Range("AH11:AH32,AN11:AN32").SpecialCells(xlCellTypeFormulas)
        s = rng.Formula
        p2 = InStr(s, "/")
        If p2 > 0 Then
            If InStr(s, "ROUND") = 0 Then
                p1 = InStrRev(s, ",", p2 - 1)
                If p1 = 0 Then
                    p1 = InStrRev(s, "(", p2 - 1)
                    If p1 = 0 Then
                        p1 = InStrRev(s, "=", p2 - 1)
                    End If
                End If
                If p1 = 0 Then
                    MsgBox "Houston, we have a problem with cell " & rng.Address & "!", vbExclamation
                    Stop
                Else
                    p3 = InStr(p2 + 1, s, ")")
                    If p3 = 0 Then
                        p3 = Len(s) + 1
                    End If
                    s = Left(s, p1) & "ROUND(" & Mid(s, p1 + 1, p3 - p1 - 1) & ",2)" & Mid(s, p3)
                    rng.Formula = s
                End If
            End If
        End If
    Next rng
    Application.ScreenUpdating = True
End Sub
