Counting All Characters

When you work with worksheets—particularly those from other people—you may be looking for a way count the number of characters in a worksheet. The following macro is very handy in that regard. It counts the number of characters in an entire workbook, including any characters in any text boxes inserted in the various worksheets.

Sub CountCharacters()
    Dim wks As Worksheet
    Dim rng As Range
    Dim rCell As Range
    Dim shp As Shape

    Dim bPossibleError As Boolean
    Dim bSkipMe As Boolean

    Dim lTotal As Long
    Dim lTotal2 As Long
    Dim lConstants As Long
    Dim lFormulas As Long
    Dim lFormulaValues As Long
    Dim lTxtBox As Long
    Dim sMsg As String

    On Error GoTo ErrHandler
    Application.ScreenUpdating = False

    lTotal = 0
    lTotal2 = 0
    lConstants = 0
    lFormulas = 0
    lFormulaValues = 0
    lTxtBox = 0
    bPossibleError = False
    bSkipMe = False
    sMsg = ""

    For Each wks In ActiveWorkbook.Worksheets
        ' Count characters in text boxes
        For Each shp In wks.Shapes
            If TypeName(shp) <> "GroupObject" Then
                lTxtBox = lTxtBox + shp.TextFrame.Characters.Count
            End If
        Next shp

        ' Count characters in cells containing constants
        bPossibleError = True
        Set rng = wks.UsedRange.SpecialCells(xlCellTypeConstants)
        If bSkipMe Then
            bSkipMe = False
        Else
            For Each rCell In rng
                lConstants = lConstants + Len(rCell.Value)
            Next rCell
        End If

        ' Count characters in cells containing formulas
        bPossibleError = True
        Set rng = wks.UsedRange.SpecialCells(xlCellTypeFormulas)
        If bSkipMe Then
            bSkipMe = False
        Else
            For Each rCell In rng
                lFormulaValues = lFormulaValues + Len(rCell.Value)
                lFormulas = lFormulas + Len(rCell.Formula)
            Next rCell
        End If
    Next wks

    sMsg = Format(lTxtBox, "#,##0") & _
      " Characters in text boxes" & vbCrLf
    sMsg = sMsg & Format(lConstants, "#,##0") & _
      " Characters in constants" & vbCrLf & vbCrLf

    lTotal = lTxtBox + lConstants

    sMsg = sMsg & Format(lTotal, "#,##0") & _
      " Total characters (as constants)" & vbCrLf & vbCrLf

    sMsg = sMsg & Format(lFormulaValues, "#,##0") & _
      " Characters in formulas (as values)" & vbCrLf
    sMsg = sMsg & Format(lFormulas, "#,##0") & _
      " Characters in formulas (as formulas)" & vbCrLf & vbCrLf

    lTotal2 = lTotal + lFormulas
    lTotal = lTotal + lFormulaValues

    sMsg = sMsg & Format(lTotal, "#,##0") & _
      " Total characters (with formulas as values)" & vbCrLf
    sMsg = sMsg & Format(lTotal2, "#,##0") & _
      " Total characters (with formulas as formulas)"

    MsgBox Prompt:=sMsg, Title:="Character count"

ExitHandler:
    Application.ScreenUpdating = True
    Exit Sub

ErrHandler:
    If bPossibleError And Err.Number = 1004 Then
        bPossibleError = False
        bSkipMe = True
        Resume Next
    Else
        MsgBox Err.Number & ": " & Err.Description
        Resume ExitHandler
    End If
End Sub

The macro may seem quite long, but it is very well structured in exactly what it does. First, it looks through all the text boxes in a worksheet. If they are not grouped (you cannot count characters in grouped text boxes), then the characters in them are tallied up. Then the macro tallies up the characters in cells containing constants. Finally, it counts all the characters used in cells containing formulas. The balance of the macro is used to present the information in a message box.
