Which function would you use to find out how many characters are in a cell?

To determine the number of characters in a cell, the LEN() function is used. This function counts all characters in a specified cell, including letters, numbers, spaces, and punctuation. The primary purpose of LEN() is to efficiently return the total character count, which is valuable when analyzing data for formatting, validation, or data cleaning tasks.

For instance, if you had a cell containing the text "Hello, World!" the LEN() function would return 13, reflecting the total count of all characters in that string.

The other functions listed do not exist in Excel for this specific purpose. CHARACTERCOUNT(), COUNTCHAR(), and CELLCOUNT() are not valid functions in Excel, making LEN() the only correct choice for counting characters in a cell.
