Using Excel's LEN() Function

 The LEN() function in Excel is used to count the number of characters in a text string. Here's how to use it:

Syntax: LEN(text)

text: The text string for which you want to count the number of characters.

Example:

Suppose you have a text string "Hello, World!" in cell A1. To count the number of characters in this text string, you would use the following formula:

=LEN(A1)

This formula would return the value 13 because "Hello, World!" contains 13 characters, including letters, punctuation, and spaces.

The LEN() function is helpful for various tasks, such as validating data lengths, truncating long text strings, or performing text-based analysis.
