Excel LOWER Function

Excel allows a user to convert all letters of a string to lower-case, by using the LOWER function. This step by step tutorial will assist all levels of Excel users in converting text to lower-case.

Figure 1. The result of the LOWER function

Syntax of the LOWER Formula

The generic formula for the LOWER function is:


The parameter of the LOWER function is:

  • text – a text which we want to convert to lower-case.

Convert the Text to Lower-case Using the LOWER

In our example, we want to convert the text to lower-case. The text is “CONVERT TO Lower case”.

The formula looks like:


The parameter text is “CONVERT TO Lower case”.

To apply the IF function, we need to follow these steps:

  • Select cell B3 and click on it
  • Insert the formula: =LOWER("CONVERT TO Lower CASE")
  • Press enter

Figure 2. Using the LOWER function to convert the text to lower-case

As you can see in Figure 2, all letters of the text are converted to lower-case. Therefore, the result in the cell B3 is “convert to lower case”.

Using the LOWER Function to Convert Text from the Cell

In this example, we will provide cell reference to the function, instead of text. The example is similar, but now we put the text in the cell B3 and want to get the result in C3.

The formula is:


To apply the IF function, we need to follow these steps:

  • Select cell C3 and click on it
  • Insert the formula: =LOWER(B3)
  • Press enter

Figure 3. Using the LOWER function to convert the text from the cell

The result is the same as in the previous example. The cell C3 now has the value “convert to lower case”.
