Vba button Comparison data between two file or two tabs

[Thainguyen]

I got a template layout and i normally copy and paste all customer data in my template and saved. However, a lot of time customer send me same data but they added in few new data. But some of the old data is not the same row or cell as the old one.

I have code that scans and compares old excel list with new excel list, and then pastes all of the differences between the two into a new sheet. My code is working properly - However, This code is only compare cell by cell. It don't work if there is a new row inserted between old rows.

How can I improve the code to look only for new data added in the new excel file and avoid display all the same data that listed on different row? What should I change or add in my code?

I've tried researching on Google and Stack Overflow, but couldn't find much relevant information.


Here is my full code (let me know if you need me to provide more):

Sub Compare2WorkSheets(ws1 As Worksheet, ws2 As Worksheet)  
Dim ws1row As Long, ws2row As Long, ws1col As Integer, ws2col As Integer
Dim maxrow As Long, maxcol As Integer, colval1 As String, colval2 As     String
Dim report As Workbook, difference As Long
Dim row As Long, col As Integer
Set report = Workbooks.Add
With ws1.UsedRange
ws1row = .Rows.Count
ws1col = .Columns.Count
End With
With ws2.UsedRange
ws2row = .Rows.Count
ws2col = .Columns.Count
End With
maxrow = ws1row
maxcol = ws1col
If maxrow < ws2row Then maxrow = ws2row
If maxcol < ws2col Then maxcol = ws2col
difference = 0
For col = 1 To maxcol
  For row = 1 To maxrow
  colval1 = ""
  colval2 = ""
  colval1 = ws1.Cells(row, col).Formula
  colval2 = ws2.Cells(row, col).Formula
  If colval1 <> colval2 Then
 difference = difference + 1
 Cells(row, col).Formula = colval1 & "<> " & colval2
 Cells(row, col).Interior.Color = 255
 Cells(row, col).Font.ColorIndex = 2
 Cells(row, col).Font.Bold = True
  End If
Next row
Next col
Columns("A:B").ColumnWidth = 25
report.Saved = True
If difference = 0 Then
report.Close False
End If
Set report = Nothing
MsgBox difference & " cells contain different data! ", vbInformation,     "Comparing Two Worksheets"
End Sub

Private Sub CommandButton1_Click()
'Compare2WorkSheets Worksheets("Sheet1"), Worksheets("Sheet2")
Set myWorkbook1 = Workbooks.Open("C:\familycomputerclub-website\Excel2007    \testcompare2.xlsx")
Compare2WorkSheets Workbooks("testcompare1.xlsm").Worksheets("Sheet1"),     myWorkbook1.Worksheets("Sheet1")
End Sub
