Determining the Length of a String

Written by Allen Wyatt (last updated December 17, 2022)

It is hard to imagine a function used more often with strings than the Len function. This simple little function returns the length of any string. The following are a few examples:

A = Len(MyString)
B = Len("This is a test")

The first line returns the length of the characters in the variable MyString. The second returns the number of characters between the quote marks (in this case, 14—remember that spaces count as characters).

If you want to determine the length of the information in a particular cell, you follow a bit different approach:

C = Len(ActiveCell.Text)

When this line is executed, it returns the length of whatever is displayed in the currently selected cell. It is important to note that since it relies on the .Text property, the code returns the length of what is displayed in the cell, not what is actually contained within the cell.
