Excel VBA StrConv Function

The StrConv function in VBA comes under String functions, a conversion function. One may use this function because it changes the case of the string with the input provided by the developer. In addition, the arguments of this function are the string. So, for example, the input for a case like 1 is to change the string to lowercase.

StrConv stands for “String Conversion.” We can convert the supplied string to the specified format using this VBA functionVBA functions serve the primary purpose to carry out specific calculations and to return a value. Therefore, in VBA, we use syntax to specify the parameters and data type while defining the function. Such functions are called user-defined functions.read more. You need to understand that we can use this formula as a VBA function only, not as an Excel worksheet function. This article will tour detailed examples of the “VBA StrConv” formula.

Look at the syntax of the StrConv function.

String: This is nothing but the text we are trying to convert.

Conversion: What kind of conversion do we need to do? We have a wide variety of options. Here, below is the list of conversions we can perform.

• vbUpperCase or 1: This option converts the supplied Text value to upper case character. It works similarly to the UCASE function. For example, if you supply the word “Excel,” it will convert to “EXCEL.”
• vbLowerCase or 2: This option converts the supplied Text value to lowercase character in excelThere are six methods to change lowercase in excel — Using the lower function to change case in excel, Using the VBA command button, VBA shortcut key, Using Flash Fill, Enter text in lower case only, Using Microsoft word.
  read more. It works similarly to the LCASE function. For example, if you supply the word “Excel,” it will convert to “excel.”
• vbProperCase or 3: This option converts the supplied Text value to the proper case character. Every first character of the word converts to uppercase. All the remaining letters convert to lowercase. For example, if you supply the word “excEL,” it will convert to “Excel.”
• vbUniCode or 64: This option converts the string to Unicode code.
• vbFromUnicode or 128: It converts the string Unicode to the default system code.

Even though we have several other options with the Conversion argument above, three are good enough for us.

LCID: This is the Locale ID. By default, it takes the system ID. It will not use 99% of the time.

Examples of StrConv Function in VBA

You can download this VBA StrConv Function Template here – VBA StrConv Function Template

Example #1

Now, look at the example of converting the string to the UPPER CASE character. We are using the word “Excel VBA” here. Below is the VBA codeVBA code refers to a set of instructions written by the user in the Visual Basic Applications programming language on a Visual Basic Editor (VBE) to perform a specific task.read more.

Code:

Sub StrConv_Example1()

    Dim TextValues As String
    Dim Result As String

    TextValues = "Excel vba"

    Result = StrConv(TextValues, vbUpperCase)

    MsgBox Result

End Sub

It will convert the string “Excel VBA” to upper case.

Run this code using the F5 key or manually and see the result.

Example #2

Now, take a look at the same string with lowercase conversion. Below is the code.

Code:

Sub StrConv_Example2()

    Dim TextValues As String
    Dim Result As String

    TextValues = "Excel vba"

    Result = StrConv(TextValues, vbLowerCase)

    MsgBox Result

End Sub

It will convert the string “Excel VBA” to a lowercase.

You can run it manually or through excel shortcut keyAn Excel shortcut is a technique of performing a manual task in a quicker way.read more F5. Below is the result.

Example #3

Now, take a look at the same string with proper case conversion. Below is the code.

Code:

Sub StrConv_Example3()

    Dim TextValues As String
    Dim Result As String

    TextValues = "Excel vba"

    Result = StrConv(TextValues, vbProperCase)

    MsgBox Result

End Sub

It will convert the string “Excel VBA” to a proper case. Every first letter of the string is upper case. Moreover, it converts every letter after space to uppercase. All the remaining characters convert to lowercase. Below is the result of the same.

Example #4

Now, look at the Unicode character’s example. Look at the below code.

Code:

Sub StrConv_Example4()

  Dim i As Long
  Dim x() As Byte
  x = StrConv("ExcelVBA", vbFromUnicode)
  For i = 0 To UBound(x)
  Debug.Print x(i)
 Next

End Sub

It will print all the Unicode characters to the immediate window.

In ASCII code, “E” Unicode is 69, “x” Unicode is 120, and so on. Like this, using VBA StrConv, we can convert the string to Unicode.

This tutorial will demonstrate how to use the UCASE, LCASE and STRCONV functions in VBA.

While working in VBA, you often need to convert strings into lowercase, uppercase or proper case. This is possible by using the UCase, LCase and StrConv functions.

These functions are important when manipulating strings in VBA, as VBA is case sensitive. If you wish to make VBA case-insensitive, you need to add Option Compare Text at the top of your module. You can find out more about this here: Prevent VBA Case Sensitive

UCase – Convert String to Upper Case

The UCase function in VBA converts all letters of a string into uppercase. There is only one argument, which can be a string, variable with string or a cell value. This function is often used if you want to compare two strings. Here is the code for the UCase function:

Dim strText As String
Dim strTextUCase As String

strText = "running Uppercase function"

strTextUCase = UCase(strText)

MsgBox strTextUCase

In the example, we want to convert all letters of the strText variable to upper case and assign the converted string to the strTextUCase variable. At the end we call the message box with the converted string:

LCase – Convert String to Lower Case

If you want to convert all letters of a string into lower cases, you need to use the LCase function. This function has one argument, the same as the UCase. This is the code for the LCase function:

Dim strText As String
Dim strTextLCase As String

strText = "RUNNING lowerCASE FUNCTION"

strTextLCase = LCase(strText)

MsgBox strTextLCase

In this example, we convert all letters of the string variable strText into lower case. After that, the converted string is assigned to the variable strTextLCase.

StrConv – Convert String to Proper Case

The StrConv function enables you to convert a string of text into proper case. The function has two arguments. First is the string that you want to convert. The second is the type of the conversion which you want. In order to convert a string to a proper case, you need to set it to vbProperCase. The code for the function is:

Dim strText As String
Dim strTextProperCase As String
    
strText = "running proper case function"
    
strTextProperCase = StrConv(strText, vbProperCase)
    
MsgBox strTextProperCase

You will see on the example how the function works. It takes the string from the cell B1, converts it to proper case and returns the value in the cell A1.

StrConv – Convert String to Upper or Lower Case

Using the StrConv function, you can also convert a string to upper or lower cases. To do this, you just need to set the second argument to the vbUpperCase or vbLowerCase:

strTextConverted = StrConv(strText, vbUpperCase)

strTextConverted = StrConv(strText, vbLowerCase)

VBA Upper, Lower, and Proper Case – Case Functions in Access

All of the above examples work exactly the same in Access VBA as in Excel VBA.

Private Sub ClientName_AfterUpdate()
   'this will convert the text in the client name box to uppercase
   Me.ClientName = UCase(Me.ClientName)
End Sub
