# LOWER Excel Function

## What Is LOWER Function In Excel?

The LOWER Excel function converts the uppercase or capital letters of the selected string into lowercase or small letters. LOWER function is an in-built Text function, so we can insert the formula from the “Function Library” or enter it directly in the worksheet. For example, we will use the LOWER function to return the lowercase string.

Select cell B2, enter the formula =LOWER(A2), and press the “Enter” key. The result is the lowercase “a”, as shown below. Therefore, the capital letter is converted to a small letter.

###### Key Takeaways
• The LOWER Excel function converts all the capital letters in the selected text into lowercase letters.
• In a combination of uppercase and lowercase letters like ABCDefgh, the lowercase letters remain untouched, and the function will convert to lowercase and give the result as abcdefgh.
• The function reduces the time consumption in rewriting and recorrecting the strings in a large dataset.
• We can generate email ids from names using this function by using the “&” symbol to merge the names with the domain name.
