将多个Excel工作簿合并到单个主列表中

Question

我有以下代码，虽然不完整，因为我不确定如何填充多个列和行。

代码

Sub VlookMultipleWorkbooks()

    Dim lookFor As Range
    Dim srchRange As Range

    Dim book1 As Workbook
    Dim book2 As Workbook

    Dim book1Name As String
    book1Name = "destination.xls"    'modify it as per your requirement

    Dim book1NamePath As String
    book1NamePath = ThisWorkbook.Path & "\" & book1Name

    Dim book2Name As String
    book2Name = "source.xls"    'modify it as per your requirement

    Dim book2NamePath As String
    book2NamePath = ThisWorkbook.Path & "\" & book2Name

'    Set book1 = ThisWorkbook
    Set book1 = Workbooks(book1Name)

    If IsOpen(book2Name) = False Then Workbooks.Open (book2NamePath)
    Set book2 = Workbooks(book2Name)

    Set lookFor = book1.Sheets(1).Cells(2, 1)   ' value to find
    Set srchRange = book2.Sheets(1).Range("A:B")    'source

    lookFor.Offset(0, 1).Value = Application.VLookup(lookFor, srchRange, 2, False)

End Sub

我的源文件具有以下结构

Name     Value1

我的目标文件具有以下结构

Name     Value1

问题1

目前，代码只填充单个单元格，我希望它填充允许行。

问题2

我需要能够填充多个列。例如。

Name     Value1     Value2, etc

问题3

有多个源文件需要合并到一个主列表中。

Answer 1

编辑：您可以修改初始设计以接收两个Range个对象和一个偏移量，然后根据需要进行迭代。您需要打开工作簿并将Range对象分配到其他位置，但这似乎不是现在的挑战。 （以下未经测试）：

Sub EvenCoolerVLookup(SourceRange As Range, OffsetColumns As Long, LookupRange As Range)

Dim Cell As Range

'vet range objects and make sure they fail an Is Nothing test
'....

For Each Cell In SourceRange
    'do any special prep here
    '...
    Cell.Offset(0, OffsetColumns).Value = Application.VLookup(Cell, LookupRange, 2, False)
    'do any special cleanup here
    '...
Next Cell

'do anything else here
'....

End Sub

这应该可以帮助您解决问题1 。要解决问题2 ，您将无法使用Application.Vlookup，但您可以使用Range.Find返回Range对象，您可以使用该对象通过Range.Row抓住该行。

原始回复：这应该可以合并问题3 的源文件。结果将作为xlsx文件保存到与运行代码的文件相同的目录中：
