VBA Length of String

What is VBA Length of String?

VBA Len is a significant tool for data validation. VBA LEN function Returns the number of characters in a supplied string i.e. to measure the length of text or number of characters in a text. VBA LEN is categorized under the String function. It can be used as either procedure or function in the VBA editor window. It is frequently used as a support function along with other string functions like MID, RIGHT i.e. To pullout name parts from a full name.

Syntax of VBA Length of String in Excel

The syntax for VBA Length of String function in excel is as follows:

After typing LEN click on spacebar, the above-mentioned syntax appears where it contains the below-mentioned argument.

• String: It is an expression or a text string or a variable name from which you want to return the length.

i.e. Len(“Length”) = return the value 6, because the length of the text “Length” is 6. If you take a variable as Variant instead of long then it is considered the same as a string. i.e. the Len functions treat the variant variable as a String.

How to Use Length of String Function in Excel VBA?

Below are the different examples to use Length of string in Excel using VBA code.

VBA Length of String – Example #1

Follow the below steps to use a length of string function in excel VBA.

Step 1: Go to the Developers tab and click on Visual Basic.

Step 2: Open a Module from the Insert menu option as shown below.

Step 3: Under the Microsoft Excel objects, right-click on sheet 1 (VB_LEN) Insert and under the menu section select Module, so that a new blank module gets created.

VBA Length of String – Example #2

Suppose, I have the word “NULL” and I want to find out the number of characters in this text string i.e. for this, with the help of VB LEN function macro code, I can find out.

Step 1: In the VBA editor, I have given a name as LENGTH() after typing Sub

Sub LENGTH()

End Sub

Step 2: As VBA LEN function is categorized under string type, DIM (Dimension) is used in a VBA code to declare a variable name, it’s type. In VBA, you need to always declare initially that you are setting up a variable. This is done (mostly) with the word Dim.

DIM is used to declare variable & storage allocation for variable.

Syntax: Dim [Insert Variable Name] as [Insert Variable Type]

Code:

Sub LENGTH()

Dim L As Variant

End Sub

Step 3: After declaring a variable, Assign a value to this variable with the help of LEN function.

Code:

Sub LENGTH()

Dim L As Variant
L = Len (

End Sub

Step 4: After typing LEN and click on the spacebar and once you enter open bracket below mentioned syntax appears for the right function.

String: It is an expression or a text string or a variable name from which you want to return length i.e. “LENGTH”

Code:

Sub LENGTH()

Dim L As Variant
L = Len("LENGTH")

MsgBox L

End Sub

Once you finished typing LEN function arguments. Now, I want to display this result of the len function in the message box. then in the next line of code, let’s click on Ctrl + Space, type MsgBox after this you can mention a variable name.

Step 5: Now, the code is ready, you can run it by click on the F5 key. Once you do that, Pop up message appears, with a result in it as “6” which indicates the number of characters in a supplied string or text (Length)

VBA Length of String – Example #3

Now, instead of output appearing in the message box, I want the result or output data to appear in the worksheet. In the worksheet, I have a data, i.e. USA state in the cell “A4”, now I want to find out a number of characters in the text string of state, Here I can use Len function with slight modification in the code.

Step 1: After declaring a variable, I have to input the variable name again and cell address of the full-text string with the help of Range or cell function.

Code:

Sub TEXT_LENGTH()

Dim L As Variant
L = Range("A4")

End Sub

Step 2: Now, again I need to enter a variable name, and apply LEN function & input its arguments.

Code:

Sub TEXT_LENGTH()

Dim L As Variant
L = Range("A4")
L = Len("Massachusetts")

End Sub

In the previous example,  we entered msg box for the result to be displayed, now, I want the result to appear in a specific cell in a worksheet. for this, I  need to enter range or cell function for the result to be displayed.

Step 3: Now, let’s apply range function, initially I need to input the range or cell function and later enter the variable name, so that in that specific cell (“B4”), the result appears.

Code:

Sub TEXT_LENGTH()

Dim L As Variant
L = Range("A4")
L = Len("Massachusetts")
Range("B4").Value = L

End Sub

Step 4: Now, the code is ready, I can run it by click on the F5 key. once I do that, you can observe an output value of LEN function appearing in the cell “B4” i.e. 13 which indicates the number of characters in a supplied string or text.

Things to Remember

• Apart from LEN function, LenB is used to calculate or to find out the actual number of required bytes for a provided variable in memory.
• Object variable should not be used in Len function.
