How to use LOWER Function in Excel?

Uncovering the hidden steps to use the LOWER function are written below −

Step 1 − Expedite the new Excel worksheet.

Step 2 − Import the dataset from the web or create the sample dataset.

Step 3 − Double-click on the target cell, type the = sign, write the LOWER, and then start the bracket (.

Step 4 − Define a single cell reference or cell range and then enclose ) a bracket. For example, the LOWER function becomes like =LOWER(B3:B7).

Step 5 − Hit the Enter tab.

Example of LOWER Function

Practice the following example to learn the use of the LOWER function in Excel.

Example 1

Converting the qualitative data into lowercase using the LOWER function.

Solution

Step 1 − Assume the sample dataset where input strings are written in the B column.

LOWER Function

Step 2 − First, enter the formula =LOWER(B3) into the C3 cell.

LOWER Function 1

After that, press the Enter tab to get the resulting value.

LOWER Function 2

Step 3 − Furthermore, double-click on the C3 cell and press the ctrl + c keys to copy this formula =LOWER(B3) and paste it into the cell range C4:C9 to extract all the text strings in the lowercase.

LOWER Function 3

Finally, the LOWER function will transform all the text strings into the lowercase.

LOWER Function 4

Example 2

Using LEFT and LOWER functions for extracting text.

Solution

Step 1 − If you intend to extract only a substring in lowercase from the input text, you can merge the LOWER function with the LEFT function. Select the C2 cell and type the formula =LEFT(LOWER(B2),5).

LOWER Function 5

Explanation

=LEFT(LOWER(B2),5)

1. In this formula, the B2 cell points to the text string Excel Functions. The Lower function converts it into lowercase letters.

2. The LEFT function extracts only five characters of the converted text string from the front side.

Step 2 − Hit the Enter tab. Hence, the formula retrieves the excel as a result.
