VBA VARTYPE Function

Excel VBA VarType Function

VBA VARTYPE means “Variable Type”. This function helps us to identify the data type assigned to the specific variable or in simple word we can say it finds what kind of value is stored or assigned to the variable.

Syntax

VarName: We just need to supply the variable name to find the data stored in the supplied variable name.

So, it takes the variable name as the syntax or argument, and in the output, it returns the data type assigned to the variable or the kind of data stored in the variable.

So, if you have ever wondered how to find the variable data type or the kind of data assigned to the variable, then here we have a VBA functionVBA 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 “VarType.”

Examples

Example #1

In VBA, while writing the code, we usually declare variables and assign a data type to them. For example, look at the below VBA codeVBA 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 VarType_Example()

    Dim MyVar As String

    MyVar = "Hello"

End Sub

In the above example, we have declared the variable as “String,” and for this string, we have assigned the value as “Hello.”

This is a straightforward case, but it is also possible to declare the variables without assigning the variables to them, so in such cases, the VarType function helps us.

Code:

Sub VarType_Example()

    Dim MyVar

    MyVar = "Hello"

End Sub

In the above code, we have not assigned any data type but straight away assigned the value as “Hello,” so by using the VarType function, we can find the data type of the variable.

Open MSGBOX in VBAOpen MSGBOX In VBAVBA MsgBox function is an output function which displays the generalized message provided by the developer. This statement has no arguments and the personalized messages in this function are written under the double quotes while for the values the variable reference is provided.read more coding in the above code.

Then open the VarType function.

Now enter the variable name as the argument of the VARTYPE function.

Code:

Sub VarType_Example()

    Dim MyVar

    MyVar = "Hello"

    MsgBox VarType(MyVar)

End Sub

Now run the code and see what we get in the message box.

We got the result as 8 because VBA has certain codes for each kind of variable data type, so below is the detailed list for you.

Value	Constant	Description
0	vbEmpty	Variable is not yet initialized
1	vbNull	Not valid data is assigned
2	vbInteger	The variable value is “Integer” data type
3	vbLong	The variable value is “Long” data type
4	vbSingle	The variable value is “Single” data type
5	vbDouble	The variable value is “Double” data type
6	vbCurrency	The variable value is “Currency” data type
7	vbDate	The variable value is “Date” data type
8	vbString	The variable value is “String” data type
9	vbObject	The variable value is “Object” data type
10	vbError	The variable value is Error Value
11	vbBoolean	The variable value is “Boolean” data type
12	vbVariant	The variable value is “Variant” data type (used only with arrays of variants)
13	vbDataObject	The variable value is the Data Access Object
14	vbDecimal	The variable value is “Decimal” data type
17	vbByte	The variable value is “Byte” data type
20	vbLongLong	The variable value is “LONG LONG” data type (valid on 64-bit platforms only)
36	vbUserDefinedType	The variable value is “User Defined” data type
8192	vbArray	The variable value is Array.

Ok, now our code has retuned the variable data type as 8, i.e., the variable name “MyVar” contains the “String” data type.

Example #2

Now, look at the below code.

Code:

Sub VarType_Example2()

    Dim MyVar

    Set MyVar = ThisWorkbook

    MsgBox VarType(MyVar)

End Sub

Let’s run this code and see what the result is.

The result is 9, i.e., variable contained the “Object” data type. Yes, this is correct because, for the variable “MyVar,” we have set the workbook reference of “This Workbook.”

Example #3

Now, look at the below code.

Code:

Sub VarType_Example3()

    Dim MyVar

    MyVar = 32500

    MsgBox VarType(MyVar)

End Sub

This will return the result as 2.

Because the number 32500, which is assigned to the variable, is an “Integer” value.

Now I will change the value to 40000 and see the result.

Code:

Sub VarType_Example4()

    Dim MyVar

    MyVar = 40000

    MsgBox VarType(MyVar)

End Sub

This will give the result as 3.

Because Integer value is ending at 32767, so anything above that will be treated as a VBA LONG data typeVBA LONG Data TypeLong is a data type in VBA that is used to store numeric values. We know that integers also store numeric values, but Long differs from integers in that the range for data storage is much larger in the case of long data type.read more.

Now I will enclose the number in double-quotes.

Code:

Sub VarType_Example5()

    Dim MyVar

    MyVar = "40000"

    MsgBox VarType(MyVar)

End Sub

Run the code and see the result.

We got the result as 8, i.e., String data type.

This is because anything supplied within the parenthesis will be treated as a String variable.

Things to Remember

• VARTYPE stands for “Variable Type.”
• Data Type is represented by unique numbers so refer to the table to understand which number represents which variable data type.
