To following procedure demonstrates the use of the Left, Right, Mid, and Len functions of Microsoft Visual Basic for Applications in Microsoft Excel:
  1. Create a new, blank Microsoft Excel workbook.
  2. Open the Visual Basic Editor by pressing ALT+F11.
  3. On the Insert menu, click Module.
  4. Type the following macro in the new module sheet:

      Sub String_Len()
          ' Sets MyString.
          MyString = InputBox("Enter some text.")
          ' Displays length of string.
          MsgBox Prompt:="The length of the string is " & _
              Len(MyString) & " characters."
      End Sub

      Sub String_Left()
          ' Sets MyString.
          MyString = InputBox("Enter some text.")
          StringLen = Len(MyString)
          Pos = InputBox("Please enter a number from 1 to " & StringLen)
          ' Takes the left number of specified characters.
          Result = Left(MyString, Pos)
          ' Displays the result.
          MsgBox Prompt:="The left " & Pos & " characters of """ & _
              MyString & """ are: " & _
              Chr(13) & Result
      End Sub

      Sub String_Right()
          ' Sets MyString.
          MyString = InputBox("Enter some text.")
          StringLen = Len(MyString)
          Pos = InputBox("Please enter a number from 1 to " & StringLen)
          ' Takes the right number of specified digits.
          Result = Right(MyString, Pos)
          ' Displays the result.
          MsgBox Prompt:="The right " & Pos & " characters of """ & _
              MyString & """ are: " & _
              Chr(13) & Result
      End Sub

      Sub String_Mid()
          ' Sets MyString.
          MyString = InputBox("Enter some text.")
          ' Sets starting position.
          StartPos = InputBox _
              ("Give me a starting position (1 to " _
              & Len(MyString) & ")")
          ' Determines length of string of text.
          StringLen = Len(MyString) - StartPos + 1
          ' Sets number of characters.
          NumChars = InputBox _
              ("How many characters would you like? (From 1 to " & _
              StringLen & ")")
          MsgBox prompt:="The result is: " & _
              Mid(MyString, StartPos, NumChars)
      End Sub
