How to check if two ranges value is equal

Question

I want to merge cells in columns, if there is the same value in whole row.
Eg. If A1:G1 range is the same as A2:G2 I want to merge A1:A2 cells, B1:B2 to G1:G2.
With my code below I get run time error 13: type mismatch. I'm assuming, that problem is with checking equality of two ranges.

Dim i As Long, j As Long, row as Long
row = Cells(Rows.Count, 6).End(xlUp).row
For i = row To 7 Step -1
        If Range(Cells(i, 7), Cells(i, 24)).Value = Range(Cells(i - 1, 7), Cells(i - 1, 24)).Value Then
        For j = 7 To 24 Step 1
            Range(Cells(i, j), Cells(i - 1, j)).Merge
        Next j
        End If
Next i

The question is, how to check if both ranges values are equal?

Edit after comments: With the code below it actually works

Dim i As Long, j As Long, row As Long
row = Cells(Rows.Count, 6).End(xlUp).row
For i = row To 7 Step -1
        If Join(Application.Transpose(Application.Transpose(Range(Cells(i, 7), Cells(i, 24)))), Chr(0)) = Join(Application.Transpose(Application.Transpose(Range(Cells(i - 1, 7), Cells(i - 1, 24)))), Chr(0)) Then
        For j = 7 To 24 Step 1
            Range(Cells(i, j), Cells(i - 1, j)).Merge
            Application.DisplayAlerts = False
        Next j
        End If
Next i

However, I'm wondering, why you(@Pᴇʜ) separeted the function for first and last rows.

Also, with my code, without merging cells I had te loop for change cell color:

Dim row As Long
row = Cells(Rows.Count, 6).End(xlUp).ro
Do Until IsEmpty(Cells(row, 3))
     If row Mod 2 <> 0 Then
       Range(Cells(row, 3), Cells(row, 24)).Interior.Color = RGB(217, 225, 242)
     Else
       Range(Cells(row, 3), Cells(row, 24)).Interior.Color = xlNone
     End If
     row = row + 1
Loop

How to deal with that after cells are merged?

Answer 1

The issue is that …

Range(Cells(i, 7), Cells(i, 24)).Value

returns an array of values, but you cannot compare an array of values with =. Therefore you need to loop throug all these values and compare each value with the corresponding value in

Range(Cells(i - 1, 7), Cells(i - 1, 24)).Value

Since you already have this loop just move your If statement to check this into the loop:

Dim iRow As Long, iCol As Long, LastRow as Long
LastRow = Cells(Rows.Count, 6).End(xlUp).row
For iRow = LastRow To 7 Step -1
    For iCol = 7 To 24 Step 1
        If Cells(iRow, iCol).Value = Cells(iRow - 1, iCol).Value Then
            Range(Cells(iRow, iCol), Cells(iRow - 1, iCol)).Merge
        End If
    Next iCol 
Next iRow 

Note that I changed the variable naming to more meaningful names. This also avoids using Row as variable name which is alerady used by Excel itself.

Option Explicit

Sub Test()
    Dim RangeToMerge As Range
    Set RangeToMerge = Range("C5:F14")

    Dim FirstMergeRow As Long
    FirstMergeRow = 1

    Dim iRow As Long, iCol As Long
    For iRow = 1 To RangeToMerge.Rows.Count - 1
        If Join(Application.WorksheetFunction.Transpose(Application.WorksheetFunction.Transpose(RangeToMerge.Rows(FirstMergeRow).Value)), "|") <> _
           Join(Application.WorksheetFunction.Transpose(Application.WorksheetFunction.Transpose(RangeToMerge.Rows(iRow + 1).Value)), "|") Then
            If iRow <> FirstMergeRow Then
                For iCol = 1 To RangeToMerge.Columns.Count
                    Application.DisplayAlerts = False
                    RangeToMerge.Cells(FirstMergeRow, iCol).Resize(rowsize:=iRow - FirstMergeRow + 1).Merge
                    Application.DisplayAlerts = True
                Next iCol
            End If
            FirstMergeRow = iRow + 1
        End If
    Next iRow

    'merge last ones
    If iRow <> FirstMergeRow Then
        For iCol = 1 To RangeToMerge.Columns.Count
            Application.DisplayAlerts = False
            RangeToMerge.Cells(FirstMergeRow, iCol).Resize(rowsize:=iRow - FirstMergeRow + 1).Merge
            Application.DisplayAlerts = True
        Next iCol
    End If
End Sub

The value property of a range returns an array if the range has more than one cell. You can either compare the values of each element in a loop, or you can use join() to convert the arrays to strings and then compare those (see this answer).
