Not sure I understand. You have cells F4:K4 with either blanks or values.
You want to change theses cells or other cells?

Easy case: change other cells
In some other cell (say F5) enter =IF(ISBLANK(F4),0,62.50)
Format the cell as currency
Copy the formula across the row

Change the actual cells: that will require VBA

Sub tryme()
myrow = 4
For mycol = 6 To 10
If Cells(myrow, mycol).Value = "" Or Cells(myrow, mycol).Value = 0 Then
Cells(myrow, mycol).Value = 0
Else
Cells(myrow, mycol).Value = 62.5
Cells(myrow, mycol).NumberFormat = "$#,##0.00_);($#,##0.00)"
End If
Next
End Sub

New to VBA? See one or both of these:
