若EXCEL工作表有很多合并的单元格，要将所有合并的单元格撤销，并填充撤销合并前显示的内容，这是一项很繁琐且容易出错的工作。但可通过宏程序可轻松准确地搞定，方法如下：
一、实现该功能的Excel宏程序(复制即可)
Private Sub CXHB()
Dim i As Range
For Each i In ActiveSheet.UsedRange
If i.Address <> i.MergeArea.Address And i.Address = i.MergeArea.Item(1).Address Then
i.MergeArea.Select
i.MergeArea.UnMerge
' MsgBox (i.MergeArea.Address)
Selection.FillDown
End If
Next i
End Sub

二、合并多个相同内容的excel文件
Sub 合并当前目录下所有工作簿的全部工作表()
Dim MyPath, MyName, AWbName
Dim Wb As Workbook, WbN As String
Dim G As Long
Dim Num As Long
Dim BOX As String
Application.ScreenUpdating = False
MyPath = ActiveWorkbook.Path
MyName = Dir(MyPath & "\" & "*.xls")
AWbName = ActiveWorkbook.Name
Num = 0
Do While MyName <> ""
If MyName <> AWbName Then
Set Wb = Workbooks.Open(MyPath & "\" & MyName)
Num = Num + 1
With Workbooks(1).ActiveSheet
.Cells(.Range("B65536").End(xlUp).Row + 2, 1) = Left(MyName, Len(MyName) - 4)
For G = 1 To Sheets.Count
Wb.Sheets(G).UsedRange.Copy .Cells(.Range("B65536").End(xlUp).Row + 1, 1)
Next
WbN = WbN & Chr(13) & Wb.Name
Wb.Close False
End With
End If
MyName = Dir
Loop
Range("B1").Select
Application.ScreenUpdating = True
MsgBox "共合并了" & Num & "个工作薄下的全部工作表。如下：" & Chr(13) & WbN, vbInformation, "提示"
End Sub
