# How to Count Cells that Contain only numbers in Excel

This post will guide you how to** count the number of cells that only contain numbers **within a range of cells using a formula in Excel 2013/2016.

## Count Number of Cells that Contain Numbers

Assuming that you have a data list in the range of cells B1:B6, and you want count the number of cells containing only numbers, and write the result in cell D1.You can use a formula based on the COUNT function Like this:

**=COUNT (B1:B6)**

The Syntax of COUNT function is as below:

**=COUNT(value1,value2…)**

Note: Value1 is reequired, which can be a cell range, a row or a column.

You would see that the above formula COUNT function should be count number of cells contain only number within the range B1:B6.

If you want to count the number of cells that does not contain numbers, and you can use a formula based on the SUMPRODUCT function and the ISNUMBER function, like this:

**=SUMPRODUCT(–NOT(ISNUMBER(B1:B6)))**

Let’s see that how this formula works:

**=ISNUMBER(B1:B6)**

The ISNUMBER function can be used to search number in the range B1:B6 and returns TRUE or FALSE values. The above function would return an array result;

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

**=NOT(ISNUMBER(B1:B6))**

The NOT function will convert the above array result in reverse. And the result still is an array like this:

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

Then you need to use double negative operator convert the above result array into 1 and 0, like this:

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

The SUMPRODUCT function will be used to add the array and return final result.
