There may be better ways, especially in later versions in than my XL97 but
assuming that the last used row is Row 250 then you could use:

Sub Merger()
LastRow = 250
Application.ScreenUpdating = False
For x = 1 To Columns.Count
Columns(x).Select
If Selection.Columns.Count 1 Then
For y = 1 To LastRow
Cells(y, x).Select
If Selection.Columns.Count 1 Then
Application.ScreenUpdating = True
Cells(y, x).Select
MsgBox "Merged cell " & Cells(y,
x).Address
GoTo GetOut
Application.ScreenUpdating = False
End If
Next y
End If
Next x
GetOut:
Application.ScreenUpdating = True
End Sub

The code will stop after you dismiss the messagebox so that you can unmerge
the cells then run the code again.

When trying to sort a worksheet, a box is displayed saying "This
operation requires the merged cells to be identically sized".

(The current worksheet contains data copied from a number of other
worksheets)

In the current worksheet, how do I find which cell(s) are the merged
cells?
