This Excel VBA tutorial explains how to use LEN Function to measure length of text.
Excel VBA LEN Function
Excel VBA LEN Function is to measure the length of text, to be more precise, the number of characters in a text.
LEN Function is most useful as a tool for data validation where length of text always have limit in a system.
LEN Function is also commonly used in conjunction with other functions:
LEFT Function – extract a substring on the left
RIGHT Function – extract a substring on the right
MID Function – extract a substring in the middle of the string
INSTR Function – return starting position of a substring (first occurance) in a string
Syntax of VBA Excel LEN Function
The Syntax of VBA LEN Function is same as that in spreadsheet.
|text||The text string from which you want to return length|
Example of Excel VBA LEN Function
Suppose Cell A1 contains address Flat A, ABC Street,
Cell B1 contains a full name Peter, Gilbert
|LEN(Range(“A1”).Value)||19||Total 19 characters in the string (including space)|
|LEFT(Range(“A1”).Value,LEN(Range(“A1”).Value)-1)||Flat A, ABC Street||Extract substring from left excluding the ending comma|
|MID(Range(“B1”).Value,INSTR(Range(“B1″).Value,”,”)+1,LEN(Range(“B1”).Value))||Gilbert||Extract substring from (comma position+1) to (length of whole string)|
The below example demonstrates how to count number of “e” in the string “Peter, Gilbert” by looping through each character in a string.
Public Sub countE() Dim Val As String Val = "Peter, Gilbert" For i = 1 To Len(Val) If Mid(Val, i, 1) = "e" Then counter = counter + 1 End If Next i MsgBox (counter) End Sub
