5 Suitable Examples to Use Excel VBA StrConv Function
Example 1: Converting String to Uppercase Using VBA StrConv
From the syntax, we know that the VBA StrConv function converts text strings into specified formats as instructed in the Conversion Types section. In this case, we just convert a simple text string (i.e., “vba test string”) into an Uppercase text format. To do so, we have to write a simple VBA Macro Code with the StrConv function. A typical VBA Macro Code has a format to proceed with maintaining certain criteria depending on any project.
➤ Paste the following macro code in a Module of Microsoft Visual Basic window,
Sub VBA_StrConv_Function() Dim mString as String Dim mResultString As String mString = "vba test string" mResultString = StrConv(mString, vbUpperCase) MsgBox "The delivered string to Uppercase is :" & mResultString, vbInformation, "VBA_StrConv_Function_Uppercase" End Sub
➤ in the code,
1 – start the macro procedure by declaring the Sub name. You can assign any name to the code.
2 – define the variable mString and mResultString as String. We can also declare the variable type as Long. Because both String and Long variables define texts.
3 – assign the mString and mResultString to text (i.e., “vba test string”) and function (i.e., StrConv) respectively.
4 – show the outcome in a message box with a specified format.
➤ Press F5 to run the Macro and it brings out a message box depicting the function’s outcome.
Example 2: VBA StrConv Converts String to Lowercase
Similar to the Uppercase example, we can display a string in Lowercase. In order to do so, we have to execute the following sequences.
➤ Write the following code in a Module of Microsoft Visual Basic window.
Sub VBA_StrConv_Function() Dim mString as String Dim mResultString As String mString = "vba test string" mResultString = StrConv(mString, vbLowerCase) MsgBox "The delivered string to Lowercase is :" & mResultString, vbInformation, "VBA_StrConv_Function_Lowercase" End Sub
➤ From the above image, in the sections,
1 – begin the macro code declaring the Sub name.
2 – declare the variables sString and mResultString as String. As we assign it to the resultant value of StrConv function, it must be a text String.
3 – provide the values to the variables. Variable mString refers to the text (i.e., “vba test string”) and mResultString the StrConv function value.
4 – the formatted text shows up in a message box.
➤ Hit F5 to run the Macro and it displays a message box with the formatted text string in it.
Example 3: Converting String to Proper Case Using VBA StrConv
Proper Case is one of the Conversion Types available in the StrConv function. We can reduce the hassle of changing the first letters in each word in any writing such as essays, product intros, etc.
➤ Use the below code in any Module in Microsoft Visual Basic window.
Sub VBA_StrConv_Function_Propercase() Dim mString as String Dim mResultString As String mString = "vba test string" mResultString = StrConv(mString, vbProperCase) MsgBox "The delivered string to Proper Case is:" & mResultString, vbInformation, "VBA_StrConv_Function_Propercase" End Sub
➤ The code’s sections,
1 – initiate the macro procedure declaring the Sub name.
2 – declare the variable sString and mResultString as String. As we mentioned earlier, you can declare the variables as Long also.
3 – assign the values to variables. Where mString = “vba test string”, mResultString = StrConv(mString, vbProperCase). mResultString is the resultant value that the latter message box will show with format.
4 – fetch the formatted outcome in a message box.
➤ Use F5 to run the macro and it brings out a message box with the given text formatted.

Example 4: Converting String to Unicode
Unicode is an international standard for handling, representing text. We can convert a string into Unicode standard just using the VBA StrConv function. And Unicode is one of the Conversion types referred to in the function’s syntax.
➤ Type the following code in a Module of Microsoft Visual Basic window.
Sub VBA_StrConv_Function_Unicode() Dim mString As String, mResultString As String Dim iCunt As Integer Dim fString() As Byte mString = "vba test string" fString = StrConv(mString, vbUnicode) For iCunt = 0 To UBound(fString) mResultString = mResultString & fString(iCunt) Next MsgBox "The delivered string in Unicode is: " & mResultString, vbInformation, "VBA_StrConv_Function_Unicode" End Sub
➤ From the above image, the code’s sections,
1 – take forward the macro by setting the Sub name.
2 – declares the variables mString, mResultString as String. Also iCunt as Integer, fString() as Byte. We declare fString() as Byte because we store Unicode characters here.
3 – set mString equals to the String (i.e., “vba test string”). The fString equals the StrConv function. For Loop iCunt equals 0 to UBound function which returns an array length of fString. In the end, mResultString is assigned to equal mResultString & fString(iCunt).
4 – display the Unicode characters in a message box.
➤ Press F5 to run the Macro and it brings out a message box depicting the Unicode characters.

Example 5: Converting String from Reference Cell
For earlier examples, we get results in message boxes. What if we want to assign the texts from a cell reference and make them appear Uppercase in certain cells? We can achieve it using cell references in formulas. You can convert texts into other conversion types as you wish. However, in this method, we only show Uppercase to be the formatted text version.
➤ Let’s say we have texts in cells (i.e., B3 and B4) as shown in the image below.
➤ Paste the following code in a Module.
Option Explicit Sub VBA_StrConv_CellReference() Range("C3").Value = StrConv(Range("B3"), vbUpperCase) Range("C4").Value = StrConv(Range("B4"), vbUpperCase) End Sub
➤ The code is marked in parts,
1 – begin the macro by setting the Sub name.
2 – allow the formula to fetch text from cells (i.e., B3 and B4) then convert it as instructed (i.e., Uppercase) by the formula.
➤ Push the F5 key to run the Macro and it makes the converted texts appear in destined cells.
⧭ Things to Keep in Mind
🔄 VBA StrConv is only applicable for texts.
🔄 We can use Both String and Long variables to define any text.
🔄 Must save the Excel workbook as Macro Enabled Excel format to use the macros in the future.
In this article, we discuss and demonstrate the uses of the VBA StrConv function. We try to clear the basics and cover typical uses of this function.
