Introduction to LEN Formula in Excel
LEN function categorized under text functions in excel. LEN is used to count the number of characters in a text or string. It is the length function used to calculate the length of a string which contains special characters, space, numbers, letters, etc. This will count the characters in a string including space or special characters. This always returns a number as output. The string can be directly mentioned in the function by expressing the string within a double quotation or refereeing a cell. If the cell contains the text or string in which you want to find the count of characters, then cell address can be used with the LEN function.

How to Use LEN Formula in Excel?
LEN Formula in Excel is very simple and easy. Let’s understand how to use the LEN Formula in Excel with some examples.
Example #1 – Find Out the Length of Text

After applying the Len formula the result shown below.
Drag the same formula for the rest of the cells.
Example #2 – Calculate Length in a Text with Different Characters
Below is an example of how the length is calculated in a text with different characters.
The length is detected as 2 since space exists before the character given.
The Text consists of only two characters and the Length is returned as 2.
The Text included a special character and is counted along with the text. While checking you can see there found only two characters can be seen in the cell, but the Length is detected as 15. This happened because of a couple of leading spaces and spaces between the numbers.
Apply the formula in cell C2.
Similarly, apply the same formula in Cell C3.
The Length for each text is shown and in the first text, a special character is included and is counted with the length formula.
The LEN Formula does not count formatting Length, here the count of 100 only calculated.
Example #3 – Using Double Quotation in Len Function
You can directly give the string to the LEN function, where the string is mentioned in the double quotation.
=LEN(“This is len function”)
The result will be as given below.
Example #4 – Count the Characters Excluding the Extra Spaces
We have the details of the order numbers. And when we apply the Excel LEN formula it returned the number of characters. But it included the unwanted spaces between the numbers.
Apply the LEN formula in Cell B2.
The result will be as given below.
Drag the Cell B2. The number of characters returned. The numbers included the space between numbers so the length is not unique.
To get the number of characters after avoiding these extra spaces let’s use the substitute function along with the Excel LEN Formula. Select the Cell C2 and apply the formula =LEN(SUBSTITUTE(A2,” “,””))
The result will be as given below.
Drag the formula to the rest of the cell. SUBSTITUTE(A2,” “,””)) and then operate with the LEN formula. The function ‘SUBSTITUTE(A2,” ”,””)’ will replace the spaces with null. In the formula will work as string or text given in C2, space will be replaced by null in C2.
And the formula LEN (SUBSTITUTE(A2,” “,””)) will find the number of characters in C2 after replacing the space. When the unwanted spaces are removed the number of characters returned the same value.
Things to Remember About LEN Formula in Excel
