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

uppercase macro code

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

Lowercase macro code

  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

propercase macro code-VBA StrConv

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

Unicode macro code-VBA StrConv

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.

Cell reference

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

Cell reference macro code

 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.

Cell reference result


⧭ 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.

🔄 StrConv function formats in macros such as Lowercase, Uppercase, or Proper Case work in similar ways to the same functions in Excel.


Conclusion

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. I hope the above-described uses of the VBA StrConv function intrigue you to use the function more efficiently. If you have further queries or feedback, please let me know in the comment section.

    Microsoft doc says that Unicode functions of Strconv are not available on Mac.
    vbNarrow/Wide functions change the code unit size (bytes per character) – nothing to do with spacing.

    • Hello, Nick! Right now we’re not working with Mac so unfortunately we’re unable to provide you with the exact solutions.
