The LEN function is used to count characters in Excel. But it doesn’t support ranges or arrays to easily count total number of characters in a range. *This *article shows 2 ways to count characters in Excel in a range which uses SUMPRODUCT and SUM along with LEN.

## Syntax

=SUMPRODUCT(LEN(range))

{=SUM(LEN(range))}

## 1. Using SUMPRODUCT

The LEN function simply returns the count of characters in the argument. All special characters like space, new line character, minus in negative numbers, point in decimal number etc. are counted.

See the article How to count the number of characters inside a cell for more information on LEN.

Using the LEN function with an array causes *#VALUE!* error like any other non-array functions. To make a non-array function handle arrays, we can use the SUMPRODUCT formula.

All you need to do is to wrap your function with SUMPRODUCT. The LEN function will return an array of character counts in each cell in the range.

LEN(B3:B7) returns *{5;59;4;5;4}*

Next step is that the SUMPRODUCT to sum all values in the array.

=SUMPRODUCT(LEN(B3:B7)) returns *77*

## 2. Using SUM and Array Formula

By defining a formula as an array, you can make it return an array of values which is calculated for each cell in the range. To make a formula an array, press *Ctrl + Shift + Enter* key combination instead of regular *Enter*. Excel wraps the formula with curly brackets ({}).

Note: Excel puts the curly brackets itself after pressing *Ctrl + Shift + Enter*. Do not type them manually.

Using LEN function with a range returns error. But the same function as an array formula returns an array.

{=LEN(B3:B7)} returns *{5;59;4;5;4}*

However; if you use the LEN function by itself in a cell, it only shows the 1^{st} value of the array, *5* in this case. But if you use SUM formula it will return the sum of all values in the array.

{=SUM(LEN(B3:B7))} returns *77*
