VBA LEN

Len function is a common function for both worksheet and VBA, it is an inbuilt function for both of the platforms and the syntax to use this function is also 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 same as it returns the length of a string.

VBA LEN Function

VBA LEN function returns the “length of the string” i.e. it returns how many characters are there in the supplied value. Of all the string functions in VBA, “LEN” is the most under-utilized function. I 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 the sentence “Hello Guys, Good Morning!!!” and you if you want to find the number of characters in it how do you find it? In this article, we will show you the “VBA LEN” function.

Formula of VBA LEN Function

LEN function has only one syntax i.e. Expression.

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

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

Examples

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 below VBA code.

Code:

Sub LEN_Example()

    Dim Total_Length As String

    Total_Length = Len("Excel VBA")

    MsgBox Total_Length

End Sub

In the above code variable is “Total_Length”.

Dim Total_Length As String

For this variable, we have assigned 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 I run this code using the F5 key or manually, we will get 9 as a result because space is also a character.

VBA LEN as Support Function

Example #1

The purpose of the LEN function mostly utilized with other functions. I have used this function with RIGHT & Instr functions.

For example, look at the below sample data.

From the above data, we need to extract Date separately and Remarks Separately. Copy the above data to your excel sheet and paste in Cell A1.

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

Code:

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)

     Next

End Sub

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

Example #2

Now I will show you how to use VBA Length of string as a support function to extract the last name of the full name with RIGHT & Instr function.

For the demonstration look at the below data.

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

Code:

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
     Next

End Sub

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