Excel VBA，数据转换导致Excel崩溃。

Question

Excel VBA，数据转换导致Excel崩溃。

3

我有一段代码会导致我的Excel崩溃，它从一个工作表中获取数据并将其从表格视图转换为垂直视图。我认为它很慢是因为它将其从数据库视图转换成了超过45k行的数据。

有人有优化这段代码的提示吗？在next c循环处会导致Excel崩溃。

此外，我尝试在Excel 2010中运行此代码，但出现overflow错误，但通常情况下，2010运行更好，而2013则较慢或无响应。但我想让它在2013中正常工作。

Sub test()
    Call ReversePivotTable("Sheet1", "A", "C", "Sheet2", "Name")
End Sub



Sub ReversePivotTable(source_sheet, from_col, to_col, target_sheet, Optional type_header = "type", Optional value_header = "value")

    Application.ScreenUpdating = False
    LAST_ROW = Sheets(source_sheet).Cells(Rows.count, 1).End(xlUp).Row
    If LAST_ROW > 1 Then
        Sheets(target_sheet).Cells.ClearContents
    Else
        Exit Sub
    End If

    pvt_type_col = Sheets(target_sheet).Range(to_col & 1).Offset(0, 1).column 'D
    pvt_value_col = Sheets(target_sheet).Range(to_col & 1).Offset(0, 2).column 'E

    'get headers
    Sheets(source_sheet).Range(from_col & ":" & to_col).copy
    Sheets(target_sheet).Range("A1").PasteSpecial xlPasteValues
    Sheets(target_sheet).Cells(1, pvt_type_col).Value = type_header
    Sheets(target_sheet).Cells(1, pvt_value_col).Value = value_header



    'tranform data

试试这个：

    Call ReversePivotTable("Sheet1", "A", "C", "Sheet2", "Name")
End Sub



Sub ReversePivotTable(source_sheet, from_col, to_col, target_sheet, Optional type_header = "type", Optional value_header = "value")

    Application.ScreenUpdating = False
    LAST_ROW = Sheets(source_sheet).Cells(Rows.Count, 1).End(xlUp).Row
    If LAST_ROW > 1 Then
        Sheets(target_sheet).Cells.ClearContents
    Else
        Exit Sub
    End If

    pvt_type_col = Sheets(target_sheet).Range(to_col & 1).Offset(0, 1).Column 'D
    pvt_value_col = Sheets(target_sheet).Range(to_col & 1).Offset(0, 2).Column 'E

    'get headers
    Sheets(source_sheet).Range(from_col & ":" & to_col).Copy
    Sheets(target_sheet).Range("A1").PasteSpecial xlPasteValues
    Sheets(target_sheet).Cells(1, pvt_type_col).Value = type_header
    Sheets(target_sheet).Cells(1, pvt_value_col).Value = value_header

    'tranform data
    curr_row = 2
    With Sheets(source_sheet)
        last_col = .Cells(1, Columns.Count).End(xlToLeft).Column
            For Each c In .Range("A2", .Range("A" & Rows.Count).End(xlUp))
                Set Rng = .Range(.Cells(c.Row, pvt_type_col), .Cells(c.Row, last_col))
                numbers = Application.WorksheetFunction.CountIf(Rng, "<>""")
                If numbers > 0 Then
                    Sheets(target_sheet).Range(from_col & curr_row & ":" & from_col & curr_row + numbers - 1).Value = Sheets(source_sheet).Range(from_col & c.Row & ":" & to_col & c.Row).Value

                            Sheets(target_sheet).Cells(b, pvt_value_col) = .Cells(c.Row, a)
                            b = b + 1
                        End If
                    Next a
                    curr_row = curr_row + numbers

谢谢您的回复。在数据转换部分的“Next c”部分，我仍然遇到了Excel无响应的问题。 - excelguy

我实际上创建了样本数据并检查了你原始的代码和我展示的版本。你的代码完成时间很长 - 可能较慢的机器会崩溃。然而，纠正后的版本 - 在其中我将值分配给单元格而不是复制它们 - 是非常快的（我已经创建了45k行的样本数据）。如果可能的话，请展示一个你用这个宏的实际数据的例子。 - Pawel Czyz

我可以给您发送一个样品表格吗？您能在聊天中给我发消息吗？ - excelguy

抱歉，但我不想为一系列原因分析您的代码甚至使用它... 首先，在VBA编程中常见的错误是使用未指定（未声明）的变量。这会引起多种问题，特别是当程序员出现拼写错误（打字错误）时，例如，他使用了myvairable而不是myvariable。因此...强烈建议使用Option Explicit语句，因为...正如MSDN文档所述：如果您没有指定数据类型，则默认情况下将分配Variant数据类型。（...） Variant类型的变量需要比大多数其他变量更多的内存资源（...）如果模块包含Option Explicit语句，则在Visual Basic遇到以前未声明或拼写不正确的变量名时会发生编译时错误。

有关详细信息，请参见： Wikipedia：Visual Basic for Applications VBA：声明变量运行时与编译时 Office Talk：在Office 2010的32位和64位版本中使用VBA 其次，当您尝试进行超出分配目标限制的赋值时，会发生溢出错误。该错误可能是Excel崩溃的原因。

第三点，您应该在上下文中使用代码。非上下文的代码使用可能会导致多种问题，例如数据丢失。
想象一下：有两个打开的工作簿。它们都有相同的工作表集合：Sheet1，Sheet2和Sheet3。当您使用Sheets("Sheet1").Range("A1") = "whatever"时，更改是在活动工作簿中进行的，比如说Workbook1，但是您想要在Workbook2中进行更改。明白了吗？
顺便说一下：请注意，Sheet与Worksheet不同。
Sheets与Worksheets
因此，正确使用代码上下文的方法是：

Dim srcWsh As Worksheet
Dim trgWsh As Worksheet

Set srcWsh = ThisWorkbook.Worksheets("Sheet1") 'you can use index too, see:
Set trgWsh = Workbooks("Workbook2").Worksheets(2)

trgWsh.Range("A1") = srcWsh.Range("A1")

'finally, you have to clean up
Set srcWsh = Nothing
Set trgWsh = Nothing

创建或调用过程或函数时必须使用相同的规则。

最后...
至于反转（unpivot）数据的方法...
我使用了 MSDN 的一个示例：使用 PIVOT 和 UNPIVOT，其中包含以下数据：

VendorID    Emp1    Emp2    Emp3    Emp4    Emp5
1           4       3       5       4       4
2           4       1       5       5       5
3           4       3       5       4       4
4           4       2       5       5       4
5           5       1       5       5       5

必须将其“转换”为以下形式：

VendorID    Employee    Orders
----------- ----------- ------
1            Emp1       4
1            Emp2       3 
1            Emp3       5
1            Emp4       4
1            Emp5       4
2            Emp1       4
2            Emp2       1
2            Emp3       5
2            Emp4       5
2            Emp5       5
...
