VBA Excel 2000 - Compare headers

Posted on 2011-03-25

Dear Experts,

Could you please have a look at the attached file, it contains Sheet1 and Sheet2 with certain header texts in the first row.

I know that the Excel easily can compare cell values whether those are equal like whether A1=A2, but is it possible in VBA to do this for ranges whether two ranges are the same?

At the certain example the question would be whether A1:F1 on Sheet1 is equal to A1:F1, meaning that the cells exactly are in the same order and containing the same text?

thanks,

Try this

Sub Sample()
    Dim ws1 As Worksheet, ws2 As Worksheet
    Dim boolMatch As Boolean
    
    Set ws1 = Sheets("Sheet1")
    Set ws2 = Sheets("Sheet2")
    
    ws1Value = ws1.Range("A1").Offset(X, Y).Value
    ws2Value = ws2.Range("A1").Offset(X, Y).Value
    
    boolMatch = True
    
    Do Until ws1Value = ""
        Do Until ws2Value = ""
            If ws2Value <> ws1Value Then
                boolMatch = False
                Exit Do
            End If
            X = X + 1

            ws1Value = ws1.Range("A1").Offset(X, Y).Value
            ws2Value = ws2.Range("A1").Offset(X, Y).Value
        Loop

        X = 0
        Y = Y + 1

        ws1Value = ws1.Range("A1").Offset(X, Y).Value
        ws2Value = ws2.Range("A1").Offset(X, Y).Value
    Loop
    
    If boolMatch = True Then MsgBox "Range is Identical" Else _
    MsgBox "Range is not Identical"
End Sub

Just amended the code to declare the variables. This will check if A1:F1 of Sheet1 is identical to A1:F1 of Sheet2.

Code Used

Option Explicit

Sub Sample()
    Dim ws1 As Worksheet, ws2 As Worksheet
    Dim boolMatch As Boolean
    Dim X As Long, Y As Long
    Dim ws1Value, ws2Value
    
    Set ws1 = Sheets("Sheet1")
    Set ws2 = Sheets("Sheet2")
    
    ws1Value = ws1.Range("A1").Offset(X, Y).Value
    ws2Value = ws2.Range("A1").Offset(X, Y).Value
    
    boolMatch = True
    
    Do Until ws1Value = ""
        Do Until ws2Value = ""
            If ws2Value <> ws1Value Then
                boolMatch = False
                Exit Do
            End If
            X = X + 1

            ws1Value = ws1.Range("A1").Offset(X, Y).Value
            ws2Value = ws2.Range("A1").Offset(X, Y).Value
        Loop

        X = 0
        Y = Y + 1

        ws1Value = ws1.Range("A1").Offset(X, Y).Value
        ws2Value = ws2.Range("A1").Offset(X, Y).Value
    Loop
    
    If boolMatch = True Then MsgBox "Range is Identical" Else _
    MsgBox "Range is not Identical"
End Sub

In Case you want to work with ranges like A1:F1 and A1:G1 then use this code

Option Explicit

Sub Sample()
    Dim ws1 As Worksheet, ws2 As Worksheet
    Dim boolMatch As Boolean
    Dim X As Long, Y As Long
    Dim ws1Value, ws2Value
    
    Set ws1 = Sheets("Sheet1")
    Set ws2 = Sheets("Sheet2")
    
    ws1Value = ws1.Range("A1").Offset(X, Y).Value
    ws2Value = ws2.Range("A1").Offset(X, Y).Value
    
    boolMatch = True
    
    Do Until ws2Value = ""
        If ws2Value <> ws1Value Then
            boolMatch = False
            Exit Do
        End If
        Y = Y + 1

        ws1Value = ws1.Range("A1").Offset(X, Y).Value
        ws2Value = ws2.Range("A1").Offset(X, Y).Value
    Loop
    
    If boolMatch = True Then MsgBox "Range is Identical" Else _
    MsgBox "Range is not Identical"
End Sub

Sid thanks the code, generally seems working but if on Sheet2 the cell A1 is empty, also in that case says that Range is Identical which is not true

Just also considering that why the attaced Code always brings that the Ranges are not identical?
Sub RangeCompare()
Dim Range1 As Range
Dim Range2 As Range

Set Range1 = Worksheets("Sheet1").Range("A1:F1")
Set Range2 = Worksheets("Sheet2").Range("A1:F1")

If "Range1" = "Range2" Then MsgBox "Ranges are identical" Else MsgBox "Ranges are not identical"
End Sub

Sid checking the last code, if the Sheet2 E1 cell content is empty, in that case still brings that Range is identical

Yes that is because it check A-E. I think I understood what you want.

Let me amend the code.

Sorry got tied up in the other thread.

Quick question. You want this code to simply check the headers in a row. right? And you do not want to specify a fix range (except the starting cell)?

Sid sorry I had the chance to check your comment only now,

Yes the target would be that the cells exactly are in the same order and containing the same text.

Maybe as in the logic in the below not working code, so defining two ranges and compare

Sub RangeCompare()
Dim Range1 As Range
Dim Range2 As Range

Set Range1 = Worksheets("Sheet1").Range("A1:F1")
Set Range2 = Worksheets("Sheet2").Range("A1:F1")

If "Range1" = "Range2" Then MsgBox "Ranges are identical" Else MsgBox "Ranges are not identical"
End Sub

Ok. Going as per your last post, since you are specifying Range1 and Range2 then I guess this is what you want?

Sub RangeCompare()
    Dim Range1 As Range, Range2 As Range
    Dim aCell As Range
    
    Set Range1 = Sheets("Sheet1").Range("A1:F1")
    Set Range2 = Sheets("Sheet2").Range("A1:F1")

    r1 = Range1.Row
    c1 = Range1.Column
    r2 = Range2.Row
    c2 = Range2.Column
    
    '~~> Check if they contain same number of Columns
    If Range1.Columns.Count <> Range2.Columns.Count Then
        MsgBox "Range is not identical"
        Exit Sub
    End If
    
    '~~> Check if they contain same number of Rows
    If Range1.Rows.Count <> Range2.Rows.Count Then
        MsgBox "Range is not identical"
        Exit Sub
    End If
    
    Cols = Range1.Columns.Count
    
    '~~> Check if the values are same
    For i = 1 To Cols
        If Sheets("Sheet1").Cells(r1, c1) <> Sheets("Sheet2").Cells(r2, c2) Then
            MsgBox "Range is not identical"
            Exit Sub
        End If
        c1 = c1 + 1
        c2 = c2 + 1
    Next i
    
    MsgBox "Range is identical"
End Sub
