How to correct a #VALUE! error in the IF function

IF is one of the most versatile and popular functions in Excel, and is often used multiple times in a single formula, as well as in combination with other functions. Unfortunately, because of the complexity with which IF statements can be built, it is fairly easy to run into the #VALUE! error. You can usually suppress the error by adding error-handling specific functions like ISERROR, ISERR, or IFERROR to your formula.

Problem: The argument refers to error values

When there is a cell reference to an error value, IF displays the #VALUE! error.

Solution: You can use any of the error-handling formulas such as ISERROR, ISERR, or IFERROR along with IF. The following topics explain how to use IF, ISERROR and ISERR, or IFERROR in a formula when your argument refers to error values.

IFERROR was introduced in Excel 2007, and is far more preferable to ISERROR or ISERR, as it doesn’t require a formula to be constructed redundantly. ISERROR and ISERR force a formula to be calculated twice, first to see if it evaluates to an error, then again to return its result. IFERROR only calculates once.

=IFERROR(Formula,0) is much better than =IF(ISERROR(Formula,0,Formula))

Problem: The syntax is incorrect

If a function’s syntax is not constructed correctly, it can return the #VALUE! error.

Solution: Make sure you are constructing the syntax properly. Here’s an example of a well-constructed formula that nests an IF function inside another IF function to calculate deductions based on income level.

=IF(E2 IF(the value in cell A5 is less than 31,500, then multiply the value by 15%. But IF it’s not, check to see if the value is less than 72,500. IF it is, multiply by 25%, otherwise multiply by 28%).

To use IFERROR with an existing formula, you just wrap the completed formula with IFERROR:

=IFERROR(IF(E2 Note: The evaluation values in formulas don’t have commas. If you add them, the IF function will try to use them as arguments and Excel will yell at you. On the other hand, the percentage multipliers have the % symbol. This tells Excel you want those values to be seen as percentages. Otherwise, you would need to enter them as their actual percentage values, like “E2*0.25”.

VBA IFERROR

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 VBA On Error Resume Next VBA VBA 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 excel IFERROR Function In Excel The 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?

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

Step 1: Define the variable as an integer.

Code:

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

Code:

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

Code:

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

Code:

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:

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:

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

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

This tutorial demonstrates how to use the Excel IFERROR Function to catch formula errors, replacing them with another formula, blank value, 0, or a custom message.

What Is the IFERROR Function?

IFERROR allows you to perform a calculation. If the calculation does not result in an error, then the calculation result is displayed. If the calculation does result in an error then another calculation is performed (or a static value like 0, blank, or some text is outputted).

When would you use the IFERROR Function?

• When dividing numbers to avoid errors caused by dividing by 0
• When performing lookups to prevent errors if the value isn’t found.
• When you want to perform another calculation if the first results in an error (ex. Lookup a value in a 2^nd table if it’s not found in the first table)

Un-handled formula errors can cause errors within your workbook, but visible errors also make your spreadsheet less visibly appealing.

If Error Then 0

Let’s look at a basic example. Below you are dividing two numbers. If you attempt to divide by zero you will receive an error:

Instead, insert the calculation within the IFERROR Function and if you divide by zero a 0 is outputted instead of an error:

=IFERROR(A2/B2,0)

If Error Then Blank

Instead of setting errors to 0, you can set them to ‘blank’ with double quotations (“”):

=IFERROR(A2/B2,"")

We will look at more IFERROR usages with the VLOOKUP Function…

IFERROR with VLOOKUP

Lookup functions like VLOOKUP will generate errors if the lookup value is not found. As shown above, you can use the IFERROR Function to replace errors with blanks (“”) or 0s:

=IFERROR(VLOOKUP(A2,LookupTable1!$A$2:$B$4,2,FALSE),"not found")

If Error Then Do Something Else

The IFERROR Function can also be used to perform a 2nd calculation if the 1st calculation results in an error:

=IFERROR(VLOOKUP(A2,LookupTable1!$A$2:$B$4,2,FALSE),
VLOOKUP(A2,LookupTable2!$A$2:$B$4,2,FALSE))

Here if the data is not found in ‘LookupTable1’ a VLOOKUP is performed on ‘LookupTable2’ instead.

More IFERROR Formula Examples

Nested IFERROR – VLOOKUP Multiple Sheets

You can nest an IFERROR inside another IFERROR to perform 3 separate calculations. Here we will use two IFERRORs to perform VLOOKUPs on 3 separate worksheets:

=IFERROR(VLOOKUP(A2,LookupTable1!$A$2:$B$4,2,FALSE),
IFERROR(VLOOKUP(A2,LookupTable2!$A$2:$B$4,2,FALSE),
VLOOKUP(A2,LookupTable3!$A$2:$B$4,2,FALSE)))

Index / Match & XLOOKUP

Of course, IFERROR will also work with Index / Match and XLOOKUP formulas as well.

IFERROR XLOOKUP

The XLOOKUP Function is an advanced version of the VLOOKUP function.

=IFERROR(XLOOKUP(A2,LookupTable1!$A$2:$A$4,LookupTable1!$B$2:$B$4),"Not Found")

IFERROR INDEX / MATCH

INDEX and MATCH can be used to create more powerful VLOOKUPs (similar to how the new XLOOKUP function works) in Excel.

=IFERROR(INDEX(LookupTable1!$B$2:$B$4,MATCH(A3,LookupTable1!$A$2:$A$4,0)),"Not Found")

IFERROR in Arrays

Array formulas in Excel are used to perform several calculations through a single formula. Let’s suppose there are three columns of Year, Sales, and Avg Price. You can find out the total quantity with the following formula in the E column.

{=SUM($B$2:$B$4/$C$2:$C$4)}

The formula performs well until it attempts to divde by zero, resulting in the #DIV/0! error.

You can use the IFERROR function like this to resolve the error:

{=SUM(IFERROR($B$2:$B$4/$C$2:$C$4,0))}

Notice that the IFERROR function must be nested inside the SUM Function, otherwise the IFERROR will apply to the sum total and not each individual item in the array.

IFNA vs. IFERROR

The IFNA Function works exactly the same as the IFERROR Function except the IFNA function will only catch #N/A errors. This is extremely useful when working with lookup functions: regular formula errors will still be detected, but no error will appear if the lookup value is not found.

=IFNA(VLOOKUP(A2,LookupTable1!$A$2:$B$4,2,FALSE),"Not Found")

If ISERROR

If you are still using Microsoft Excel 2003 or an older version, then you can substitute IFERROR with a combination of IF and ISERROR. Here is a brief example:

=IF(ISERROR(A2/B2),0,A2/B2)

IFERROR in Google Sheets

The IFERROR Function works exactly the same in Google Sheets as in Excel:

IFERROR Examples in VBA

VBA does not have a built-in IFERROR Fucntion, but you can also access the Excel IFERROR Function from within VBA:

Dim n as long
n = Application.WorksheetFunction.IfError(Value, value_if_error)

Application.WorksheetFunction gives you access to many (not all) Excel functions in VBA.

Typically IFERROR is used when reading values from cells.  If a cell contains an error, VBA may throw an error message when attempting to process the cell value.  Try this out with the example code below (where cell B2 contains an error):

Sub IFERROR_VBA()

Dim n As Long, m As Long

'IFERROR
n = Application.WorksheetFunction.IfError(Range("b2").Value, 0)

'No IFERROR
m = Range("b2").Value

End Sub

The code assigns cell B2 to a variable. The second variable assignment throws an error because the cell value is #N/A, but the first works fine because of the IFERROR function.

You can also use VBA to create a formula containing the IFERROR Function:

Range("C2").FormulaR1C1 = "=IFERROR(RC[-2]/RC[-1],0)"

Error handling in VBA is much different than in Excel. Typically, to handle errors in VBA, you will use VBA Error Handling. VBA Error Handling looks like this:

Sub TestWS()
    MsgBox DoesWSExist("test")
End Sub
 
Function DoesWSExist(wsName As String) As Boolean
    Dim ws As Worksheet
    
    On Error Resume Next
    Set ws = Sheets(wsName)
    
    'If Error WS Does not exist
    If Err.Number <> 0 Then
        DoesWSExist = False
    Else
        DoesWSExist = True
    End If
 
    On Error GoTo -1
End Function

Notice we use If Err.Number <> 0 Then to identify if an error has occurred.  This is a typical way to catch errors in VBA. However, the IFERROR Function has some uses when interacting with Excel cells.
