Merge cells with formula or macro?

[Guest]

I would like to merge cells in column A when the adjacent vertical cells are
the same. For example:

Col A
Row1 CX457
Row2 AG925
Row3 AG925
Row4 AG925
Row5 RB639
Row6 RB639

In this case A2, A3 & A4 would be merged, A5 & A6 would be merged. Is there
a way to do this automatically?

Thanks,
Joe M.

I'd recommend against merging cells. Why not use a conditional format and if
the cells match, have one of them change to a white font?

Merged? As in concatenated (added together to read RB639 RB639 in a
single cell)?

Or do you want to show only a single occurence if the entry occurs
multiple times?

 

[Guest]

what do you mean by merging cells?
merging can mean anything from
summing up values.
Deleting duplicates,
to formatting several cells to appear as one cell.

Sorry for not being clear. In this case, merge as to format several cells to
appear as one cell.

I have had a lotr of trouble with merged cells over the years, but a brute
force macro to do what you want would be

Sub test()
rt = 1
For r = 2 To 50000
If Cells(r, 1) = "" Then GoTo 99
If Cells(r - 1, 1) <> Cells(r, 1) Then rt = r: GoTo 99
If Cells(r - 1, 1) = Cells(r + 1, 1) Then GoTo 99
If Cells(r - 1) = Cells(r, 1) Then
Range(Cells(rt, 1), Cells(r, 1)).Select
With Selection
.HorizontalAlignment = xlGeneral
.VerticalAlignment = xlBottom
.WrapText = False
.Orientation = 0
.AddIndent = False
.IndentLevel = 0
.ShrinkToFit = False
.ReadingOrder = xlContext
.MergeCells = True
End With
End If
99
Next r

change the formating of the merged cells as you would like them to appear

End Sub
