This post will guide you how to count the number of cells that do not contain errors within a range of cells using a formula in Excel 2013/2016 or Excel office 365. How do I count the number of cells without any errors using a simple formula in Excel.

1. Count Number of Cells that do Not Contain Errors using Formula

You can use the SUMPRODUCT function in combining with NOT and ISERROR functions to count cells in a specified range of cells that do not contain errors

The below is a generic formula to count the number of cells that do not contain errors:

=SUMPRODUCT(--NOT(ISERR(range)))

Note: range is the range in which you want to count cells with no errors in the above generic form of the formula.

Supposing that you wish to count the number of cells in range B1:B6 that do not contain errors, and you can use the following formula:

=SUMPRODUCT(--NOT(ISERR(B1:B6)))

LET’S SEE THAT HOW THIS FORMULA WORKS:

= NOT(ISERR(B1:B6))

The NOT and ISERROR functions can be used to identify the cells that do not contain an error. And it returns an array result with TRUE or FALSE values. The TRUE values indicate cells without errors, and FALSE values indicate cells with error values.

The array result is like this:

{TRUE;TRUE;TRUE;FALSE;TRUE;FALSE}

= –NOT(ISERR(B1:B6))

Then you still need to convert the above array result to their numeric values, 1 and 0, so that the SUMPRODUCT function can calculate the sum of products of corresponding numbers. And you can do this with a double negative operator. And the final array result is like this:

{1;1;1;0;1;0}

The SUMPRODUCT function sums the items in the above array and return the final result.

You can also use the SUM function to count the cell that do not contain errors in range B1:B6. And the generic formula is similar with the above formula. It need to be entered as an array formula through pressing CTRL +SHIFT + Enter to convert it as array formula. The formula looks like this:

{=SUM(--NOT(ISERROR(B1:B6)))}

2. Count Cells that do not Contain Errors using User Defined Function with VBA Code

If you want to count the number of cells that do not contain errors in a range, you can write a user defined function with VBA code. Here are the steps to create and run the function:

Step1: Press Alt + F11 keys to open the Microsoft Visual Basic for Applications window.

Step2: Click Insert > Module, and paste the following code in the Module Window.

Function CountNonErrors_ExcelHow(rng As Range) As Long
    Dim cell As Range
    Dim count As Long
    count = 0
    For Each cell In rng
        If Not IsError(cell.Value) Then
            count = count + 1
        End If
    Next cell
    CountNonErrors_ExcelHow = count
End Function

Step3: Save and close the window.

Step4: In a blank cell, enter the formula:

=CountNonErrors_ExcelHow(B1:B6)

Where B1:B6 is the range you want to count.

Step5: Press Enter to get the result. This function will return the number of cells that do not contain errors in the specified range.
