With the macro below it is possible to compare the content of two worksheet ranges.
The result is displayed in a new workbook listing all cell differences.
Sub CompareWorksheetRanges(rng1 As Range, rng2 As Range)
Dim r As Long, c As Integer
Dim lr1 As Long, lr2 As Long, lc1 As Integer, lc2 As Integer
Dim maxR As Long, maxC As Integer, cf1 As String, cf2 As String
Dim rptWB As Workbook, DiffCount As Long
If rng1 Is Nothing Or rng2 Is Nothing Then Exit Sub
If rng1.Areas.Count > 1 Or rng2.Areas.Count > 1 Then
MsgBox "Can't compare multiple selections!", _
vbExclamation, "Compare Worksheet Ranges"
Exit Sub
End If
Application.ScreenUpdating = False
Application.StatusBar = "Creating the report..."
Set rptWB = Workbooks.Add
Application.DisplayAlerts = False
While Worksheets.Count > 1
Worksheets(2).Delete
Wend
Application.DisplayAlerts = True
With rng1
lr1 = .Rows.Count
lc1 = .Columns.Count
End With
With rng2
lr2 = .Rows.Count
lc2 = .Columns.Count
End With
maxR = lr1
maxC = lc1
If maxR < lr2 Then maxR = lr2
If maxC < lc2 Then maxC = lc2
If lr1 <> lr2 Or lc1 <> lc2 Then
If MsgBox("The two ranges you want to compare are of different size!" & _
Chr(13) & "Do you want to continue anyway?", _
vbQuestion + vbYesNo, "Compare Worksheet Ranges") = vbNo Then Exit Sub
End If
DiffCount = 0
For c = 1 To maxC
Application.StatusBar = "Comparing cells " & _
Format(c / maxC, "0 %") & "..."
For r = 1 To maxR
cf1 = ""
cf2 = ""
On Error Resume Next
cf1 = rng1.Cells(r, c).FormulaLocal
cf2 = rng2.Cells(r, c).FormulaLocal
On Error GoTo 0
If cf1 <> cf2 Then
DiffCount = DiffCount + 1
Cells(r, c).Formula = "'" & cf1 & " <> " & cf2
End If
Next r
Next c
Application.StatusBar = "Formatting the report..."
With Range(Cells(1, 1), Cells(maxR, maxC))
.Interior.ColorIndex = 19
With .Borders(xlEdgeTop)
.LineStyle = xlContinuous
.Weight = xlHairline
End With
With .Borders(xlEdgeRight)
.LineStyle = xlContinuous
.Weight = xlHairline
End With
With .Borders(xlEdgeLeft)
.LineStyle = xlContinuous
.Weight = xlHairline
End With
With .Borders(xlEdgeBottom)
.LineStyle = xlContinuous

End With
On Error Resume Next
With .Borders(xlInsideHorizontal)
.LineStyle = xlContinuous
.Weight = xlHairline
End With
With .Borders(xlInsideVertical)
.LineStyle = xlContinuous
.Weight = xlHairline
End With
On Error GoTo 0
End With
Columns("A:IV").ColumnWidth = 20
rptWB.Saved = True
If DiffCount = 0 Then
rptWB.Close False
End If
Set rptWB = Nothing
Application.StatusBar = False
Application.ScreenUpdating = True
MsgBox DiffCount & " cells contain different formulas!", _
vbInformation, "Compare Worksheet Ranges"
End Sub
This example macro shows how to use the macro above:
Sub TestCompareWorksheetRanges()
' compare two ranges in the active worksheet in the active workbook
CompareWorksheetRanges Range("A1:A100"), Range("B1:B100")
' compare two ranges in two different worksheets in the active workbook
CompareWorksheetRanges Worksheets(1).Range("A1:A100"), _
Worksheets(2).Range("B1:B100")
' compare two ranges in two different worksheets in two different workbooks
CompareWorksheetRanges ActiveWorkbook.Worksheets(1).Range("A1:A100"), _
Workbooks("WorkBookName.xls").Worksheets(1).Range("B1:B100")
End Sub
