Which function tells you the length of a text string by counting the characters it contains?

The function that accurately counts the number of characters in a text string is often referred to as LEN in many programming languages and data analysis tools, including SQL and Excel. This function provides a straightforward way to determine the total length of a given string, making it an essential tool for data analysts who need to analyze or manipulate text data.

For instance, if the text string is "Data Analysis", using the LEN function would return 13, as there are 13 characters in total, including spaces. The len function is commonly used because of its simplicity and effectiveness, making it integral for tasks involving string manipulation.

Other terms listed, such as LENGTH and TEXTLENGTH, are also used in various contexts but do not universally apply across all platforms. CHARCOUNT is not a standard function name in most data-related environments, which further distinguishes LEN as the correct and most recognized choice for counting text string lengths.
