SUMMARY

Microsoft Excel returns an error value for any cell that contains a formula that cannot be properly calculated. These error values include the following:
#DIV/0!
#N/A
#NAME?
#NULL!
#NUM!
#REF!
#VALUE!
This article describes a Microsoft Visual Basic for Applications Sub procedure (macro) that suppresses the error values.

If an error value is detected, the macro displays a zero instead of the cell error value.

To create and use a macro to replace an Excel error with another returned value, use the steps in the following example:
  1. Start Excel, and then press ALT+F11 to start the Visual Basic editor.
  2. On the Insert menu, click Module.
  3. In the module sheet, type the following code:
    Sub ErrorToZero()
        X = Right(ActiveCell.Formula,Len(ActiveCell.Formula)-1)
        ActiveCell.Formula = "=IF(ISERROR(" & X & "),0," & X & ")"
    End Sub
    					
  4. Press ALT+Fll to return to Excel.
  5. Select the cell that contains the formula that returns the Excel error.
  6. On the Tools menu, point to Macro, and then click Macros.
  7. In the Macro name list, click ErrorToZero, and then click Run. The cell with the formula now returns 0 (zero).
NOTES:
  • If you do not want a zero as a cell output, you can change it. In the Visual Basic for Applications code, replace the "0" on line two with the desired numeric cell output.
  • If you select an empty cell and then run the macro, a run-time error "5" will be returned.
