Summary
Although Microsoft Excel has functions that change the case of text, there are times when you may want to change text case programmatically.This article contains three sample Microsoft Visual Basic for Applications macros (Sub procedures) that you can use to change the letters in a text string to all uppercase, all lowercase, or title case (the first letter in each word is capitalized). These actions are similar to the Excel functions, =UPPER(), =LOWER(), and =PROPER().

Macro to Change All Text in a Range to Uppercase Letters
Sub Uppercase() ' Loop to cycle through each cell in the specified range. For Each x In Range("A1:A5") ' Change the text in the range to uppercase letters. x.Value = UCase(x.value) NextEnd Sub
Macro to Change All Text in a Range to Lowercase Letters
Sub Lowercase() ' Loop to cycle through each cell in the specified range. For Each x In Range("B1:B5") x.Value = LCase(x.Value) NextEnd Sub
Macro to Change All Text in a Cell Range to Initial Capital Letters
Sub Proper_Case() ' Loop to cycle through each cell in the specified range. For Each x In Range("C1:C5") ' There is not a Proper function in Visual Basic for Applications. ' So, you must use the worksheet function in the following form: x.Value = Application.Proper(x.Value) NextEnd Sub
Testing the Sample Macros
To test the sample macros, follow these steps:
-
In the same workbook that contains the macros, enter the following sample data into a new worksheet: A1: toM B1: toM C1: toM A2: sUe B2: sUe C2: sUe A3: joe SMITH B3: joe SMITH C3: joe SMITH A4: mary B4: mary C4: mary A5: LORI B5: LORI C5: LORI NOTE: This sample data contains text formatted in various cases that you can use to verify how each macro works.
-
Run each of the macros.
The text in the range specified in the macro (in the line that reads "For each x in ...") will be formatted in uppercase, lowercase, or initial capitals, as appropriate.
