# How to Count the Number of Digits in a Number in Excel

If you’re working with numbers in Microsoft Excel, you may find yourself in a situation where you need to count the number of digits in a particular number. Fortunately, Excel provides a number of functions that can help you accomplish this task. In this article, we’ll explore the different methods you can use to count the number of digits in a number in Excel.

## Understanding the Problem

Before we dive into the different methods for counting digits in Excel, it’s important to understand the problem we’re trying to solve. Essentially, we want to be able to take a number (e.g., 123456) and determine how many digits it contains. This can be useful in a variety of scenarios, such as when you’re working with large datasets and need to quickly analyze the number of digits in a particular column.

## Method 1: Using the LEN Function

One of the simplest ways to count the number of digits in a number in Excel is to use the LEN function. This function is designed to count the number of characters in a cell, so it can be used to count the number of digits in a number by first converting the number to a string.

Here’s the formula you can use:

``=LEN(TEXT(A1,"#"))``

In this formula, A1 represents the cell containing the number you want to count the digits for. The TEXT function converts the number to a string, and the “#” argument specifies that we want to include any digits in the resulting string. The LEN function then counts the number of characters in the string, which gives us the number of digits in the original number.

## Method 2: Using the SUMPRODUCT Function

Another way to count the number of digits in a number in Excel is to use the SUMPRODUCT function. This function is designed to multiply corresponding elements in arrays and then sum the products, but it can also be used to count the number of digits in a number.

Here’s the formula you can use:

``=SUMPRODUCT(LEN(A1)-LEN(SUBSTITUTE(A1,{"0","1","2","3","4","5","6","7","8","9"},"")))``

In this formula, A1 represents the cell containing the number you want to count the digits for. The SUBSTITUTE function removes all digits from the string, and then the LEN function is used to count the number of remaining characters. By subtracting this value from the original length of the string (which includes all characters), we get the number of digits in the original number.

## Method 3: Using a Custom Function

Finally, if you’re comfortable with creating custom functions in Excel, you can create your own function to count the number of digits in a number. Here’s an example function you can use:

``VbnetCopy codeFunction CountDigits(ByVal num As Long) As Integer    Dim strNum As String    Dim digitCount As Integer    strNum = CStr(num)    digitCount = 0      For i = 1 To Len(strNum)        If IsNumeric(Mid(strNum, i, 1)) Then            digitCount = digitCount + 1        End If    Next i  CountDigits = digitCountEnd Function``

To use this function, you’ll first need to add it to a module in your Excel workbook. Once it’s available, you can call the function from any cell in your worksheet by passing a number as an argument. For example, if you wanted to count the number of digits in the number 123456, you could use the following formula:

``=CountDigits(123456)``

This will return the value 6, which is the number of digits in the original number.

## Conclusion

Counting the number of digits in a number in Excel may seem like a simple task, but it can be incredibly useful in a variety of scenarios. Whether you’re working with large datasets or just need to quickly analyze a particular number, the methods we’ve explored in this article should help you get the job done.

To recap, we’ve explored three different methods for counting digits in Excel:

• Using the LEN function
• Using the SUMPRODUCT function
• Creating a custom function

Each of these methods has its own strengths and weaknesses, so it’s important to choose the one that best suits your needs.

Overall, the key takeaway here is that Excel provides a variety of powerful tools for working with numbers, and by taking the time to learn these tools, you can save yourself a lot of time and effort in the long run. So the next time you find yourself needing to count the number of digits in a number, try out one of these methods and see how it works for you.
