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 String function. It can be used as either procedure or function in VBA editor window. It is frequently used as a support function along with other string function 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 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 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
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 a 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]
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.
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”
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.
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.
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.
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.
