If you are looking for how to use the **ISERROR** function in Excel then you are in the right place. For ignoring any type of calculation error, it is better to use exception handling. MS Excel provides an ISERROR function for this purpose. This function is categorized under Information functions. This article will share the complete idea of how the RIGHT function works in Excel independently and then with other Excel functions.

**Excel ISERROR Function: Syntax & Arguments**

**Summary**

This function indicates any error value (**#N/A**, **#VALUE!**, **#REF!,** **#DIV/0!**, **#NUM!**, **#NAME?**, or **#NULL!**).

**Syntax**

**=ISERROR (value)**

**Arguments**

Argument |
Required or Optional |
Value |
---|---|---|

value |
Required | Pass the value to check for any error. |

**Note: **

- In the argument, value is provided as a cell address, but we can use it to trap errors inside more complex formulas as well.
- This
**ISERROR**function is available on Excel for Office 365, Excel 2019, Excel 2016, Excel 2013, Excel 2011 for Mac, Excel 2010, Excel 2007, Excel 2003, Excel XP, Excel 2000.

## ISERROR Function in Excel: 5 Common Examples

### Example 1: Finding Error Using ISERROR Function

Let’s have a product dataset with their **ID**, **Name**, **Total Price**, and **Quantity**. Now we find **Unit Price **for each price we will divide the total price by quantity. Here some of the cells of the **Quantity **are missing or the value is **0** which will give **#DIV/0! **In **Column F**. Now the task is to find those error-contained cells using the **ISERROR **function.

We need to find if the error is **False **or **True **in **Column G**.

- Firstly, write the formula in the
**G5**cell like this.

`=ISERROR(F5)`

- Secondly, press
**ENTER**. - Thirdly, use the
**Fill Handle**by dragging down the cursor while holding the**right-bottom**corner of the**G5**cell like this.

- Consequently, we’ll get the output like this.
- Here, the
**#DIV/0!**values in**Column F**will return**TRUE**as output in**Column G**and other normal values will return**FALSE**as output.

### Example 2: Calculating Total Error Using SUMPRODUCT and ISERROR Functions

Now let’s count the total error that we have found in the first example. For this, we need to use **the SUMPRODUCT function** additionally.

Suppose, we want to find out the total number of errors of **Column F** in the **D14 **cell.

- Firstly, write the following formula in the
**D14**cell.

`=SUMPRODUCT(--ISERROR(F5:F12))`

**Formula Explanation**

- Here
**–ISERROR(F5:F12)**this part gives a result array as we have used double unary (**—**). The value of this will be like this {0,0,0,1,0,1,0,1} - Then the
**SUMPRODUCT**function calculates the total number of True of 1 which will give 3 as we have only three two values or three 1.

- Secondly, press
**ENTER**to get the total number of errors as output. In this case, it is**3**.

### Example 3: Printing Optional Messages for Cells Containing Errors

Instead of showing the error messages, we can show any message on the **Unit Price** cell using another additional function named **the IF function**. So, we will print a message “**Quantity not Found**” in **Column F** if the quantity is **0** instead of **#DIV/0!** Error.

- So, initially, write the formula in the
**F5**cell like this.

`=IF(ISERROR(D5/E5),"Quantity not Found",D5/E5)`

**Formula Explanation**

**ISERROR(D5/E5)**this is the logical test of**IF**It will return True or False as output.**“Quantity not Found”**will be printed if the logical test value is**True**. And the logical test will be true if the**ISERROR function**finds**#DIV/0!****D5/E5**will be printed if the logical test value is**False**. That means there will be no error and the unit price will be calculated.

- Similarly, press
**ENTER**. - Thirdly, use the
**Fill Handle**and we’ll get the output as**Quantity Not Found**where errors have occurred.

### Example 4: Control Search Operation Using ISERROR Function

Now we will see how to search for anything and how to handle if there is a search item that is missing or not found in a particular dataset. We will search food names using their **ID **and show a message if the given input is not available on the dataset.

Suppose, we have an **ID **as **1155 **in the **D15 **cell. We need to get the **Food Name** in the **D16 **cell.

- Similarly, as before, write the formula in the
**D16**cell.

`= IF( ISERROR( VLOOKUP( D13, CHOOSE( {1,2}, $B$5:$B$11, $C$5:$C$11 ), 2, 0) ),`

`“Not available”, VLOOKUP( D13, CHOOSE( {1,2}, $B$5:$B$11, $C$5:$C$11 ), 2, 0) )`

**Formula Explanation**

**CHOOSE( {1,2}, $B$5:$B$13, $C$5:$C$13 )**this will return an array which will contain**ID**and**Name**{1122,” Apples”; 1133, “Eggplant”; 1144, “White Potato ”; 1155, “Mango”; 1166, “Butter”; 1188, “Cheese”; 2200,” Orange”; 2211,” Pineapple; 2222”}**VLOOKUP( D15, CHOOSE( {1,2}, $B$5:$B$13, $C$5:$C$13 ), 2, 0) )**will then look for**D15**in the array and return its 2nd column value.**ISERROR( VLOOKUP( D18, CHOOSE(..) )**will check if there is an error in function and return TRUE or FALSE.**IF (ISERROR( VLOOKUP( D15, CHOOSE(..) ), “Not available”, VLOOKUP( D15, CHOOSE() ))**will return the corresponding name of the student if present else it will return “**Not available**.”

### Example 5: ISERROR Function in VBA Code

Let’s see how we can detect any error contained in the cell using the button. There will be a code behind the button.

- Firstly,
**right-click**on the**Check Error**> select**Assign Macro**.

- Eventually, an
**Assign Macro**window will appear. - Secondly, click
**New**.

- Eventually, a new module will appear.
- Thirdly, write the following code in the module.

```
Sub Button1_Click()
'Display IsError function for cell B4 on Sheet6
MsgBox IsError(Sheet6.Range("B4")), vb0k0nly, "Check Error"
Eng Sub
```

- Fourthly, click
**Run**> select**Run Sub/UserForm**or click**F5**.

- Now type any number divided by
**0**and click on the button to check the output.

## IFERROR Vs ISERROR Functions in Excel

Both **IFERROR** and **ISERROR **functions find errors and give output but in a different way. The syntax of these two functions is also a little bit different.

The syntax of the **IFERROR **function is.

**=IFERROR(value, value_if_error)**

Eventually, the **IFERROR function** syntax has the following arguments.

**value**The argument is checked for an error.**value_if_error**The value to return if the formula evaluates to an error. The following error types are evaluated:

Suppose, we want to get errors as output in **Columns E** and **F** using **IFERROR **and **ISERROR **functions respectively.

- Firstly, write the formula in the
**E5**cell like this.

`=IFERROR(D5,"ERROR")`

- If we press
**ENTER**the error cells will give the output as**ERROR**.

On the other hand, the **ISERROR **function doesn’t give the output indicating **ERROR **directly.

It mainly gives the output showing **TRUE **or **FALSE**. By seeing this we can understand which cell has errors and which hasn’t.

- Similarly, as before, write the formula in the
**F5**cell like this.

`=ISERROR(D5)`

- After pressing
**ENTER**, we’ll get the output like this. Here the error cells will give output as**TRUE**.

## Things to Remember

- This function tests for
**#N/A**,**#VALUE!**,**#REF!**,**#DIV/0!**,**#NUM!**,**#NAME?**, and**#NULL!**Errors. - It returns logical values,
**TRUE**or**FALSE**. **ISERROR**function in Excel only checks if any given expression returns an error.

That’s all about the **ISERROR **function in Excel. Here I have tried to give a summary of this function and its different applications. Eventually, I have shown multiple methods with their respective examples but there can be many other iterations depending on numerous situations.
