1、首先打开Microsoft Office Excel 2007，新建文档并保存文件名《Excel怎样快速根据重复字段合并其它列数据.xlsm》（演示文件，下面代码复制到能运行宏的工作簿都可以），如下图。
2、然后按下快捷键ALT+F11打开VBA（宏）编辑界面，然后点菜单栏【插入】下拉中列表中点【模块（M）】如图。
3、然后插入了一个模块1，在代码框中复制如下代码：
Option Base 1
Sub 选数据根据重复字段合并()
'2020-6-28 22:15:12
Dim i As Long, j As Long, n As Long, mn, mb, myr As Range
Dim r As Long, c As Long, k As Long, mc(), j1 As Long
mb = Selection
r = UBound(mb, 1)
c = UBound(mb, 2)
On Error Resume Next
With CreateObject("scripting.dictionary")
For i = 1 To r
.Add mb(i, 1), i
Next i
mn = .Keys
End With
ReDim mc(UBound(mn) + 1, c)
k = 0
For i = 0 To UBound(mn)
k = k + 1
mc(k, 1) = mn(i)
For j = 2 To c
n = 0
For j1 = 1 To r
If mn(i) = mb(j1, 1) Then
n = n + 1
If n = 1 Then
mc(k, j) = mb(j1, j)
Else
mc(k, j) = mc(k, j) & "，" & mb(j1, j)
End If
End If
Next j1
Next j
Next i
Set myr = Application.InputBox(prompt:="选择输出数据一个单元格", Type:=8)
myr.Resize(UBound(mn) + 1, c) = mc
End Sub
4、以上操作动态过程如下：
5、回到工作表窗口，首先选原数据表，然后运行【选数据根据重复字段合并】宏（菜单栏中点【视图】中下列表中【宏】列表【查看宏(V)】打开宏对方框，选该宏名，执行），提示“选择输出数据一个单元格”，选好后输出结果，运行过程如下图。
1、上面是“，”分隔，下面代码是换行代码：
Sub 选数据根据重复字段换行合并()
'2020-6-28 22:25:12
Dim i As Long, j As Long, n As Long, mn, mb, myr As Range
Dim r As Long, c As Long, k As Long, mc(), j1 As Long
mb = Selection
r = UBound(mb, 1)
c = UBound(mb, 2)
On Error Resume Next
With CreateObject("scripting.dictionary")
For i = 1 To r
.Add mb(i, 1), i
Next i
mn = .Keys
End With
ReDim mc(UBound(mn) + 1, c)
k = 0
For i = 0 To UBound(mn)
k = k + 1
mc(k, 1) = mn(i)
For j = 2 To c
n = 0
For j1 = 1 To r
If mn(i) = mb(j1, 1) Then
n = n + 1
If n = 1 Then
mc(k, j) = mb(j1, j)
Else
mc(k, j) = mc(k, j) & Chr(10) & mb(j1, j)
End If
End If
Next j1
Next j
Next i
Set myr = Application.InputBox(prompt:="选择输出数据一个单元格", Type:=8)
myr.Resize(UBound(mn) + 1, c) = mc
End Sub
以上代码单独时要加上下面一句。
Option Base 1
2、宏运行结果如下：
