Excel数据随机生成一列非空值
1、首先打开Microsoft Office Excel 2007，新建文档并保存文件名《Excel数据随机生成一列非空值.xlsm》，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。
Option Base 1
Sub 选数据随机生成列非空值()
'2020-5-20 22:42:38
Dim i As Long, k As Long, n As Long, mn(), rn As Long, myr As Range
Set myr = Selection
n = myr.Count
k = 0
ReDim mn(n, 2)
For i = 1 To n
If myr.Cells(i).Value <> "" Then
k = k + 1
mn(k, 1) = k
mn(k, 2) = myr.Cells(i).Value
End If
Next i
Set myr = Nothing
Randomize
On Error Resume Next
With CreateObject("scripting.dictionary")
For i = 1 To k
rn = Int((k * Rnd) + 1)
.Add rn, Application.WorksheetFunction.VLookup(rn, mn, 2, False)
If Err.Number <> 0 Then
i = i - 1
End If
Err.Clear
Next i
Set myr = Application.InputBox(prompt:="选择输出随机数据一个单元格", Type:=8)
myr.Resize(.Count, 1) = Application.WorksheetFunction.Transpose(.items)
End With
End Sub
3、然后插入了一个模块1，在代码框中复制如下代码：
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【选数据随机生成列非空值】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），提示“选择输出随机数据一个单元格”，选好后输出结果，运行过程如下图。
6、上面是一列生成一列随机非空值，一行或多行多列区域也可以。运行生成结果如下图。
1、数据在单元格区域位置随机变更怎样处理？根据上面宏修改下代码，在上面模块1框复制如下代码：
Sub 选数据位置随机变换()
'2020-5-20 22:56:10
Dim i As Long, j As Long, r As Long, c As Long, n As Long, mn()
Dim mb(), rn As Long, myr As Range, k As Long, mm()
Set myr = Selection
r = myr.Rows.Count
c = myr.Columns.Count
n = myr.Count
ReDim mn(n, 2)
For i = 1 To n
mn(i, 1) = i
mn(i, 2) = myr.Cells(i).Value
Next i
Randomize
On Error Resume Next
With CreateObject("scripting.dictionary")
For i = 1 To n
rn = Int((n * Rnd) + 1)
.Add rn, Application.WorksheetFunction.VLookup(rn, mn, 2, False)
If Err.Number <> 0 Then
i = i - 1
End If
Err.Clear
Next i
mb = .items
End With
Erase mn
k = -1
ReDim mm(r, c)
For i = 1 To r
For j = 1 To c
k = k + 1
mm(i, j) = mb(k)
Next j
Next i
myr.Cells(1).Resize(r, c) = mm
End Sub
2、选数据表，然后菜单栏中点【视图】中下列表中【宏】列表【查看宏(V)】打开宏对方框，选宏名“选数据位置随机变换 ”点【执行】，生成结果。
