How to Use VBA LCase Function in Excel (3 Easy Examples)

When working in VBA, we often need to convert certain strings into lowercase, uppercase, or proper case strings. In this article, we will talk about lowercase transformation. There is a built-in function in VBA named LCase that can convert any string into lowercase. This article will share the complete idea of how the VBA LCase function works in Excel independently and then with other Excel functions.

Introduction to VBA LCase Function in Excel: Syntax & Arguments

Summary:

LCASE function converts a string to lower-case.

Syntax:

LCase(string)

Arguments:

Argument	Requirement	Explanation
string	Required	Pass the text that you want to convert to lowercase

Note:

This function affects only the Uppercase characters of the text string. Any character other than the Uppercase text characters is left unchanged.
Using a null character (or a reference to an empty cell) will return a null character.

3 Examples of Using VBA LCase Function in Excel

Example 1: Convert a String into Lowercase Using LCase Function and Present It in a Message Box

In this example, we will see how to print a message by converting them into lowercase which will be displayed in a pop-up window. For this, our text will be declared in the VBA code. For this moment we will not load the data from the worksheet. Now let’s see the process.

Steps:

Under the Developer tab, select the Marcos option (Shortcut Alt+F8).

Now give a name in the Macro name field (For me I have given Lowecase_Function_Example1) then click on Create button.

Write the code in the VBA window.

Code:

Sub Lowercase_Function_Example1()
MsgBox LCase("THIS IS A SAMPLE TEXT.")
MsgBox LCase("MAN IS MORTAL.")
End Sub

Now save the code and press the Run button then see the output (Shortcut F5).

Now we will get two windows with results. Click on the OK button to go to the next window.

Example 2: Convert Strings into Lowercase with LCase Function and Show Them in a Separate Column

Now let’s have a dataset of some foods with their names and price. But all the names of the foods are given in upper case format. Now our task is to convert all the foods’ name into lowercase and shows them in a separate column named Updated Name.

Steps:

Under the Developer tab, select Button from the Insert section. (Form Controls)

Give a name in the Assign Macro field then press the OK button.

Now give the name of the button.

Right Click on the button and select the Assign macro option.

Give a suitable name and click on the New button.

Now write the code in the VBA window.

Code:

Sub Lowercase_Button()
Dim k As Long
For k = 5 To 16
Cells(k, 3).Value = LCase(Cells(k, 2).Value)
Next k
End Sub

Code Explanation:

Dim k As Long this is declaring the K variable as long type.
For k = 5 To 16 this means K is an iteration variable and it will count from 5 to 16.
Cells(k, 3).Value = LCASE(Cells(k, 2).Value) Here we are assigning the 2nd column values (B column) to 3rd column (C column) by converting them into lowercase using LCase function.

Click on the button and see the result.

Example 3: Convert String into Lowercase Which Contains Non-Letter or Digit Characters Using LCase Function

Let’s consider the above dataset with another column ID. IDs are generated with alphabetic characters, numbers, and sometimes with special characters. Now our task is to convert the ID into lowercase. In addition, LCase doesn’t do any changes to any numbers or special characters, it only modifies alphanumeric characters.

Steps:

Like the previous example go to the VBA window and write the code and save it.

Code:

Sub Lowercase_NonLetters()
Dim rg As Range
Set rg = Selection
For Each Cell In rg
Cell.Value = LCase(Cell)
Next Cell
End Sub

Now go to the worksheet and select the ID column.

Again, shift to the VBA window and run the code (Shortcut F5).

It will automatically shift you to the worksheet and show the output.

Things to Remember

Some Common Errors with LCase Functions Are:

Output Not Showing

>> Compile the code before assigning it to any button.

“Can’t find project or library”

>> It usually means there is something out there somewhere (variable, subroutine name, etc.) with that same name. It would be best to track that down and change it so it avoids conflict, you should be able to avoid the problem by changing that line of code to this:

Target.Value = VBA.LCase(Target.Value)

Conclusion

To conclude, I have tried to give a summary of the VBA LCase function and its different applications. I have shown multiple methods with their respective examples but there can be many other iterations depending on numerous situations. That’s it all about the LCase function.
