LEN function is a common function for both worksheets and VBA. It is an inbuilt function for both platforms, and the syntax to use this function is similar. The arguments this function takes in both platforms are similar, which is a string, and the use or the output for this function is the same as it returns the length of a string.

VBA LEN Function

THE VBA LEN function returns the “length of the string” and the number of characters in the supplied value. Of all the string functions in VBA, “LEN” is the most under-utilized function. Therefore, we have seen the “VBA LEN” function used as the support function for other string functions like VBA MID Functions and VBA RIGHT function.

How do you find the length of the string or value?

For example, if you have the sentence “Hello Guys, Good Morning!!!” and you want to find the number of characters in it, how do you find it? This article will show you the “VBA LEN” function.

The formula for VBA LEN Function

The LEN function has only one syntax: Expression.

VBA Len Formula

An expression is nothing but the value we are trying to test.

For example, Len (“Good”) will return 4.


Below are the examples of VBA length of string function.

Example #1

The length of a VBA string function is very simple to use. For example, look at the VBA code below.


Sub LEN_Example()

    Dim Total_Length As String

    Total_Length = Len("Excel VBA")

    MsgBox Total_Length

End Sub
Vba len Example 1

In the above code variable is “Total_Length.”

Dim Total_Length As String

We have assigned this variable the value through the VBA LEN function.

Total_Length = Len("Excel VBA")

For the LEN function, we have assigned the value as “Excel VBA.”

Total_Length = Len("Excel VBA")

Next, we are showing the result in the VBA message box.

MsgBox Total_Length

When we run this code using the F5 key or manually, we will get 9 because space is also a character.

VBA LEN as Support Function

Example #1

The purpose of the LEN function is utilized mostly with other functions. We have used this function with RIGHT and Instr functions.

For example, look at the below sample data.

Vba len Example 2

From the above data, we need to extract dates and remarks separately. Please copy the above data to your Excel sheet and paste it into cell A1.

We need to use the LEN function with other string functions to extract these elements. The below code will do the job for us.


Sub LEN_Example1()

    Dim OurValue As String

    Dim k As Long

    For k = 2 To 6
'In this case my data started from second cell and ends at 6th.
'Based on your data change the numbers

        OurValue = ActiveSheet.Cells(k, 1).Value

       'This will extract first 10 characters i.e. Date portion
        ActiveSheet.Cells(k, 2).Value = Left(Trim(OurValue), 10)

       'This will extract teh remarks portion
        ActiveSheet.Cells(k, 3).Value = Mid(Trim(OurValue), 11, Len(Trim(OurValue)) - 10)


End Sub
length of string Example 2-1

When we run this code manually or through the F5 key, we will get the result like the one below.

Vba len Example 2-2

Example #2

Now, we will show you how to use the VBA length of string as a support function to extract the last name of the full name with the RIGHT and Instr function.

For the demonstration, look at the below data.

length of string Example 3

From the above list, we need to extract the Last Name from the full name. The below code will extract the last name. LEN is used as a support function here.


Sub LEN_Example2()

    Dim FullName As String

    Dim k As Long

    For k = 2 To 8

        FullName = ActiveSheet.Cells(k, 1).Value

        'This will extract last name
       ActiveSheet.Cells(k, 2).Value = Right(FullName, Len(FullName) - InStr(1, FullName, " "))
        'LEN finds full number of characters
        'Instr finds space character
        'LEN - Inst will gives total characters from the right

End Sub
length of string Example 2-4

Run the code using the F5 key, or you can run it manually and see the result.
