Excel VBA CSTR Function

CSTR in VBA is a data type conversion function that one may use to convert any value provided to this function to a string. For example, even if the given input is an integer or float value, this function will convert the value's data type to a string data type, so the return type of this function is a string.

How do we go about this if we need to convert any value to string data type in VBA? For this, in VBA, we have a function called "CSTR." In this article, we will guide you through the methodology of the "CSTR" function in VBA.

The String is the data type that holds any String values. When we say string, it generally refers to text values, but that is not true with VBA coding. A string can hold any order of characters as data. For example, "Hello" is treated as String, "123456" is treated as a string and "12-04-2019" as a string. This String data type can hold any order of characters.

What Does CSTR Function Do in VBA?

Have you ever thought of converting a different expression to Strings in VBA? If you have a doubt, is that possible? Then the answer is an absolute YES!

CSTR is a function covering different format expressions to String format in VBA. With the CSTR function, we can convert the provided expression value to the String data type.

VBA CSTR Syntax

Below is the syntax of the Excel VBA CSTR function.

cstr formula

The syntax of the CSTR function includes only one argument.

Expression: It is the targeted value or cell value we are trying to change to the String data type.

The value could be any data type. So, CSTR goes ahead and converts to String data type. The common data types we usually convert are Integer, Boolean, and Date to String data types.

How to Use VBA CSTR Function in Excel?

Now, we will see some examples of the Excel VBA CSTR function.

Example #1

Look at the below code.

Code:

Sub CSTR_Example1()

Dim NumericValue As Integer
Dim StringResult As String

NumericValue = 855

StringResult = CStr(NumericValue)

MsgBox StringResult

End Sub
cstr example 1.1

Firstly, we assigned the Integer data type to the variable "NumericValue" as 855. Now, the variable "NumericValue" holds the Integer data type. Another variable, "StringResult," assigned the formula CSTR to convert Integer data type to String data type.

CSTR converted the integer number to String data type. So, even though we can see the number 855, it is no longer an Integer Date Type in VBA. Instead, it is now in the String data type.

Example #2

Look at an example of VBA Boolean Data Type Conversion.

Code:

Sub CSTR_Example2()

Dim Val1 As Boolean
Dim Val2 As Boolean

Val1 = True
Val2 = False

MsgBox CStr(Val1) & vbNewLine & CStr(Val2)

End Sub
example 1.3

In the above code, I have declared two variables as Boolean.

Dim Val1 As Boolean

Dim Val2 As Boolean

In the next line, we have assigned Boolean values as TRUE and FALSE.

Val1 = True

Val2 = False

At this point, both variables are Boolean data types. Therefore, we have applied the VBA CSTR function in this example to convert this Boolean data type to a String data type.

example 2.2

Example #3

Look at the example of Date data type conversion to String data type.

Code:

Sub CSTR_Example3()

Dim Date1 As Date
Dim Date2 As Date

Date1 = #10/12/2019#
Date2 = #5/14/2019#

MsgBox CStr(Date1) & vbNewLine & CStr(Date2)

End Sub
VBA cstr example 3.1

We have declared two variables as Date.

Dim Date1 As Date

Dim Date2 As Date

Next line, we have assigned the Date values as 10-12-2019 and 05-14-2019, respectively.

Date1 = #10/12/2019#

Date2 = #5/14/2019#

At this point, both the variables are Date data types. In the next line, we have applied the CSTR function to convert the Date data type to the String data type. Like CSTR function used to convert any other data type to String data type.
