But if there is an easy way to count cells contain errors in your data range.

## Count Number of Cells that Contain Errors

You should know that there are several types of errors such as: ** #N/A**,

**or**

`#REF!`

**In Excel. And you only want to count the number of all types of errors with a formula in Excel. This tutorial will show you how to count the number of cells in a specified range of cell A1:B6 that contain errors using an Excel formula ,with the SUMRODUCT and ISERROR functions. Like below:**

`#VALUE!`

**=SUMPRODUCT(–ISERROR(A1:B6))**

**Note:** A1:B6 is the range from which to count the cells that contain errors.

**LET’S SEE THAT HOW THIS FORMULA WORKS:**

The SUMPRODUCT function can be used to multiply the corresponding components in the given arrays. If there is only one array, SUMPRODUCT function would return the sum of values in the array.

**=ISERROR(A1:B6)**

The ISERROR function is used to identify the cells that contain an error. And returns True if cell contain any error values. In this case, ISERROR function returns an array that contain TRUE or FALSE values, like this:

**={FALSE,FALSE;FALSE,FALSE;FALSE,TRUE;TRUE,FALSE;FALSE,FALSE;FALSE,TRUE}**

**=–ISERROR(A1:B6)**

You still need to convert the TRUE or FALSE values to number 1 and 0 by using a double negative operator. And the result array looks like this:

**{0,0;0,0;0,1;1,0;0,0;0,1}**

The SUMPRODUCT function would add the value of the above array and return the final result.

You can also use another array formula based on the SUM function, IF function and ISERROR function to count the number of all types of errors in a range in Excel. Like this:

**{=SUM(IF(ISERROR(A1:B6),1))}**

**Note:** you need to press **CTRL + SHIFT + ENTER** short keys to covert its as a array formula.
