Iferror in excel vba

Just like we use IFERROR in Excel to know what to do when we encounter an error before every function, we have an inbuilt IFERROR function in VBA used in the same fashion. Since it is a worksheet function, we use this function with the worksheet.function method in VBA, and then we provide the arguments for the function.

IFERROR Function in VBA

It is a crime to expect the code to function without throwing any error. To handle errors in VBA, we have several ways using statements like On Error Resume Next VBAVBA On Error Resume Statement is an error-handling aspect used for ignoring the code line because of which the error occurred and continuing with the next line right after the code line with the error.read more, On Error Resume Goto 0, On Error GoTo Label. VBA error handlers can only proceed further to the next line of code. But if the calculation does not happen, we need to replace the error with another identity word. In this article, we will see how to achieve this by using the VBA IFERROR Function in excelThe IFERROR function in Excel checks a formula (or a cell) for errors and returns a specified value in place of the error.read more.

How to use IFERROR in VBA?

The thing to remember here is it is not a VBA functionVBA functions serve the primary purpose to carry out specific calculations and to return a value. Therefore, in VBA, we use syntax to specify the parameters and data type while defining the function. Such functions are called user-defined functions.read more but rather just a worksheet function.

For example, take the above data only for a demonstration.

Step 1: Define the variable as an integer.

Code:

Sub Iferror_Example1()

  Dim i As Integer

End Sub

Step 2: To perform calculation, open For Next Loop.

Code:

Sub Iferror_Example1()

  Dim i As Integer

  For i = 2 To 6

  Next i

End Sub

Step 3: Inside, write the code as Cells(I,3).Value =

Code:

Sub Iferror_Example1()

  Dim i As Integer

  For i = 2 To 6
     Cells(i,3).Value =
  Next i

End Sub

Step 4: To access the IFERROR function, we cannot simply type the formula; we need to use the “WorksheetFunction” class.

Code:

Sub Iferror_Example1()

  Dim i As Integer

  For i = 2 To 6
    Cells(i, 3).Value = WorksheetFunction.If
  Next i

End Sub

Step 5: As you can see in the above image, after inserting the command “WorksheetFunction” class, we get the IFERROR formula. Select the formula.

Code:

Sub Iferror_Example1()

  Dim i As Integer

  For i = 2 To 6
    Cells(i, 3).Value = WorksheetFunction.IfError(
  Next i

End Sub

Step 6: One of the problems in VBA is that while accessing the worksheet functions, we do not get to see the arguments we have seen in the worksheet. It would help if you were sure about the arguments we are using.

It is the reason before we show you the IFERROR in VBA, We have shown you the syntax of the worksheet function.

The first argument is “Value,” i.e., what cell do you want to check? Before this, apply the calculation in the cell.

Now, in the VBA, apply the codes below.

Code:

Sub Iferror_Example1()

  Dim i As Integer

  For i = 2 To 6
    Cells(i, 4).Value = WorksheetFunction.IfError(Cells(i, 3).Value, "Not Found")
  Next i

End Sub

Now, the IFERROR function checks for any error in column C. If it finds any error, it will show the result as “Not Found” in column D.

Using the IFERROR function, we can alter the results per our wish. In this case, we have altered the result as “Not Found.” We can change this to your requirement.

Types of Errors, VBA IFERROR, Can Find

Knowing the types of excel errorsErrors in excel are common and often occur at times of applying formulas. The list of nine most common excel errors are — #DIV/0, #N/A, #NAME?, #NULL!, #NUM!, #REF!, #VALUE!, #####, Circular Reference.read more the IFERROR function can handle is important. Below are the kind of errors IFERROR can handle.

#N/A, #VALUE!, #REF!, #DIV/0!, #NUM!, #NAME?, or #NULL!.

VBA IFERROR

A written code many times gives the error and chances of getting an error in complex error are quite high. Like excel has IFERROR function which is used where there are chances of getting an error. IFERROR changes the error message into other text statements as required and defined by the user. Similarly, VBA IFERROR functions same as the IFERROR function of Excel. It changes the error message into the defined text by the user.

This error mostly occurs when we perform any mathematical function or if we are mapping any data which is in a different format. IFERROR handles many errors, some of them are:

#VALUE!, #N/A, #DIV/0!, #REF!, #NUM!, #NULL! And #NAME?

Example #1

Now this IFERROR function can also be implemented in VBA. Now to compare the results from Excel with VBA IFERROR we will insert a column where we will apply VBA IFERROR statement as shown below.

You can download this VBA IFERROR Excel Template here – VBA IFERROR Excel Template

For this, we consider the same data and insert another column where we will perform VBA IFERROR. Go to VBA window and insert a new Module from Insert menu as shown below.

Now in a newly opened module, write Sub-category with any name. Here we have given the name of the operating function as shown below.

Code:

Sub VBA_IfError()
End Sub

Now with the help of ActiveCell, we will select the first reference cell and then directly use IFERROR Formula with reference cell (RC) -2 divided by -1 cell numbers. Which means we are dividing cell A by cell B in the first argument. And in the second argument write any statement which we want in place of error. Here we will use the same state which we have seen above i.e. “No Product Class”.

Code:

Sub VBA_IfError()

    ActiveCell.FormulaR1C1 = "=IFERROR(RC[-2]/RC[-1],""No Product Class"")"

End Sub

Now select the range cell which would be our denominator. Here we have selected cell C2.

Code:

Sub VBA_IfError()

    ActiveCell.FormulaR1C1 = "=IFERROR(RC[-2]/RC[-1],""No Product Class"")"
    Range("C2").Select

End Sub

Now to drag the formula to below cells where we need to apply IFERROR till the table has the values.

Code:

Sub VBA_IfError()

    ActiveCell.FormulaR1C1 = "=IFERROR(RC[-2]/RC[-1],""No Product Class"")"
    Range("C2").Select
    Selection.End(xlDown).Select

End Sub

Now to come to the last cell of the column with the help of command Range where we need to drag the IFERROR formula. Here our limit ends at cell D6.

Code:

Sub VBA_IfError()

    ActiveCell.FormulaR1C1 = "=IFERROR(RC[-2]/RC[-1],""No Product Class"")"
    Range("C2").Select
    Selection.End(xlDown).Select
    Range("D6").Select

End Sub

Now to drag the applied IFERROR down to all the applicable cells select the Range from End (or Last) cell to Up to the applied formula cell by End(xlUp) command under Range.

Code:

Sub VBA_IfError()

    ActiveCell.FormulaR1C1 = "=IFERROR(RC[-2]/RC[-1],""No Product Class"")"
    Range("C2").Select
    Selection.End(xlDown).Select
    Range("D6").Select
    Range(Selection, Selection.End(xlUp)).Select

End Sub

As we do Ctrl + D to drag the up cell values to all selected cells in excel, here in VBA, Selection.FillDown is used to fill the same up cells values in all selected cells.

Code:

Sub VBA_IfError()

    ActiveCell.FormulaR1C1 = "=IFERROR(RC[-2]/RC[-1],""No Product Class"")"
    Range("C2").Select
    Selection.End(xlDown).Select
    Range("D6").Select
    Range(Selection, Selection.End(xlUp)).Select
    Selection.FillDown

End Sub

This completes the coding of VBA IFERROR. Now run the complete code by clicking on the play button as shown in below screenshot.

As we can see above, in column D starting from Cell 2 to 6 we got our results.

There is another format and way to apply IFERROR in VBA. For this, we will consider another set of data as shown below. Below we have sales data of some products in column A and quality sold in column B. And we need map this data at cell F2 with reference to product type Laptop. Now data in the first table has #N/A in cell B3 with for Laptop quantity sold out which means that source data itself has an error. And if we look up the data from the first table to Cell F2 we will get same #N/A here.

For this open a new module in VBA and write Subcategory with the name of a performed function.

Code:

Sub VBA_IfError2()

End Sub

Select range where we need to see the output or directly activate that cell by ActiveCell followed by dot (.) command line as shown below.

Code:

Now select FormulaR1C1 from the list which is used for inserting any excel function.

Now use the same formula as used in excel function in VBA as well.

Code:

Sub VBA_IfError2()

    ActiveCell.FormulaR1C1 = "=IFERROR(VLOOKUP(RC[-1],R[-1]C[-5]:R[3]C[-4],2,0),""Error In Data"")"

End Sub

Now select the cell where we need to see the output in Range. Here we have selected cell F3.

Code:

Sub VBA_IfError2()

    ActiveCell.FormulaR1C1 = "=IFERROR(VLOOKUP(RC[-1],R[-1]C[-5]:R[3]C[-4],2,0),""Error In Data"")"

    Range("B8").Select

End Sub

Now compile and run complete code using F5 key or manually and see the result as shown below.

As we can see in the above screenshot, the output of product type Laptop, from first table #N/A is with error text “Error In Data” as defined in VBA code.

Pros of VBA IFERROR Function

• It takes little time to apply the IFERROR function through VBA.
• Result from Excel insert function and VBA IFERROR coding, both are the same.
• We can format or paste special the applied formula as well to avoid any further problem.

Cons of VBA IFERROR Function

• IFERROR with this method, referencing the range of selected cell may get disturbed as the table has limited cells.

Things To Remember

• We can record the macro and modify the recorded coding as per our need.
• Always remember to save the file as Macro-Enabled Excel, so that we can use the applied or created macro multiple times without any issue.
• Make sure you remember to compile the complete code before ending the command function. By this, we can avoid or correct any error incurred.
• You can apply the created code into a button or tab and use it by a single click. This is the quickest way to run the code.
• Best way to avoid any changes after running the code is to paste special the complete cells so that there will not be any formula into the cell.

You can use the following basic syntax to use the IFERROR function in VBA to display a specific value in a cell if an error is encountered in an Excel formula:

Sub IfError()
    Dim i As Integer
    
    For i = 2 To 11
    Cells(i, 4).Value = WorksheetFunction.IfError(Cells(i, 3).Value, "Formula Error")
    Next i
End Sub

This particular example checks if each cell in rows 2 through 11 of the third column in the current sheet has an error value.

If an error value is encountered, a value of “Formula Error” is assigned to the corresponding cell in the fourth column, otherwise the numerical value from the third column is assigned to the corresponding value in the fourth column.

The following example shows how to use this syntax in practice.

Suppose we have the following dataset in Excel that shows the total revenue and units sold of some product at different stores:

Column C uses a formula to divide Revenue by Units Sold to come up with Revenue per Unit.

However, notice that the formula produces a value of #DIV/0! in some cells where we attempt to divide by zero.

Suppose we would like to create a new column that instead displays “Formula Error” for those cells.

We can create the following macro to do so:

Sub IfError()
    Dim i As Integer
    
    For i = 2 To 11
    Cells(i, 4).Value = WorksheetFunction.IfError(Cells(i, 3).Value, "Formula Error")
    Next i
End Sub

When we run this macro, we receive the following output:

The values in column D either show the results from the formula in column C or they display a value of “Formula Error” if an error value is shown.

Feel free to change “Formula Error” in the IfError method in the code to instead display whatever value you would like when an error is encountered.
