ISERROR in Excel

When doing calculations or applying formula we often get errors. To check whether the cells have an Error or not we can use Iserror Formula in Excel.

The word “IS” means it is checking whether the selected cell has an error or not. If the referred cell has an error, it will return the result as TRUE, and if the referred cell does not have an error, it will return the result as FALSE.

ISERROR function is very helpful to check the errors we got from the formulas in the sheet. This formula determines the result based on the cell value.

ISERROR finds all the bellow errors in excel. Error lists are below.

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

If the function ISERROR finds any one of this in the cell then it will return the result as TRUE or else FALSE.

ISERROR Formula in Excel

The Formula for the ISERROR Function in Excel is as follows:

ISERROR Formula in Excel

The Formula of ISERROR includes only one parameter i.e. value

Value: This is nothing but the targeted cell that you want to test.

This function is very helpful if we want to replace the error value with any other value.

How to Use ISERROR Function in Excel?

ISERROR Function in Excel is very simple and easy to use. Let understand the working of ISERROR in Excel by Some Examples.

ISERROR in Excel Example #1

Let’s look at the simple example of ISERROR Function in Excel. I have target vs actual data from Jan to May.

In column A, I have month list, in column B, I have a target list and in column C, I have achieved list.

ISERROR Example 1

I have calculated the efficiency level by dividing the achieved number by target number.

ISERROR Example 1-1

The problem is we got some errors as #DIV/0!.

If anyone of denominator or numerator is, zero we get the error as #DIV/0!When we are dividing numbers.

Let me find out which cell has an error value by using ISERROR function.

ISERROR Example 1-2

ISERROR Function returns the result as given below:

ISERROR Example 1-3

Since I have applied ISERROR Formula in Excel, if there is an error it is showing as TRUE or else showing as FALSE. Drag & drop this function and press CTRL +D for the below values.

ISERROR Example 1-4

However, this is not serving my end purpose. I want the data to be shown as zero if there is an error or else do the normal calculation.

Here I am using IF condition with ISERROR function.

ISERROR Example 1-5

A formula I have used here is:

=IF (ISERROR (C2/B2), 0%, C2/B2)

IF condition is checking if the calculation of C2/B2 is returning as an error. If the calculation returning as the error it will show the result as 0%,.or else do the calculation and show the actual percentage.

ISERROR Example 1-6

Now drag & drop this function and press CTRL +D for the below values.

ISERROR Example 1-7

How cool it is? Showing error values and replacing those error values with the 0% will make the report look beautiful.

ISERROR in Excel Example #2

We have another error function called IFERROR. It works the similar way that ISERROR works but there is slight modification are there.

Consider the below example for illustration of IFERROR function. Table 1 is the main data source and table 2 is the Vlookup table.

ISERROR Example 2

In column F, I have applied Vlookup formula to find the sales amount for laptop brands.

ISERROR Example 2-1

This VLOOKUP Function returns the result as given below:

ISERROR Example 2-2

Now drag & drop this function and press CTRL +D for the below values.

ISERROR Example 2-3

In the above table, I got an error for the brands Apple and Notepad. If you look at the main data table, there are no Apple and Notepad brands. That is why Vlookup has returned an error type as #N/A.

ISERROR Example 2-4

We can fix this issue by using the IFERROR Function.

Apply IFEEROR before VLOOKUP function. We need to write the Vlookup formula inside the IFERROR Formula.

ISERROR Example 2-5

=IFERROR (VLOOKUP (E3, $A: $B, 2, 0),”Data Not Found”). It returns the result as shown below:

ISERROR Example 2-6

Now drag & drop this function and press CTRL +D for the below values.

ISERROR Example 2-7

Firstly, IFERROR trying to find the value for the VLOOKUP formula.

Secondly, If VLOOKUP does not find a value then it will return an error. Therefore, if there is an error we will show the result as “Data Not Found”.

We have replaced all the #N/A values with “Data Not Found” text. I think this will look better than the #N/A.

ISERROR Example 2-8

Manual Method for replacing ERROR Values

However, we can replace error with ISERROR, IFERROR formula there is one manual method to do it, and that is found and replace method.

Step 1: Once the formula is applied and copy and paste only values.

Step 2: Press Ctrl + H to open replace the box and type the error value (#N/A, #DIV/0! etc). Whatever the error type you want to replace mention that error.

Step 3: Now write the replace with values as “Data Not Found”.

Step 4: Click on replace all button.

This would instantly replace all the mentioned error values with Data Not Found.

Note: If you have applied filter please choose visible cells only method to replace.

Things to Remember About ISERROR Function in Excel

  • ISERROR can make your numerical reports beautiful by removing all kinds of errors.
  • If the data contains error type and if you apply pivot tables then the same kind of error will occur in Pivot table too.
