将多个文本文件中的数据复制到现有工作表中

Question

我希望允许用户一次选择最多 5 个文本文件并将数据复制粘贴到 Excel 中的现有工作表中。每个文本文件都将添加到前一个文件之后。这意味着如果第一个文件已从 A1 列导入到 A200，则必须从 A201 行粘贴第二个文件，依此类推。我正在使用以下代码，它只允许用户选择一个文件。我希望只是将这些文本文件中的数据复制粘贴到 Excel 中，而不进行任何格式化。任何帮助将不胜感激。

Sub importdata()
Dim FileToOpen As Variant
Dim OpenBook As Workbook
    FileToOpen = Application.GetOpenFilename(Title:="Select file extracted", FileFilter:="All Files (*.*),*.*")
    If FileToOpen <> False Then
        Set OpenBook = Application.Workbooks.Open(FileToOpen)
        OpenBook.Sheets(1).Range("A:A").Copy
        ThisWorkbook.Worksheets("rawdata").Range("A1").PasteSpecial xlPasteValues
        OpenBook.Close False
     End If
End Sub

试试这个：

Option Explicit ' It is a good practice to use this to force the compiler to ask for
                ' Var declaration before use it

Sub importdata()
    Dim FileToOpen As Variant
    Dim OpenBook As Workbook
    Dim RngCopy As Range  ' Var to store the range you want to copy
    Dim RngPaste As Range ' Var to store the rante you want paste the txt file data
    Dim A As Worksheet    ' ActiveSheet of the open book stored in "OpenBook" var
    Dim B As Worksheet: Set B = ThisWorkbook.Worksheets("rawdata") '... Well RawData...
    Dim r
    Dim p
    Dim i
    FileToOpen = Application.GetOpenFilename( _
                        Title:="Select file extracted", _
                        FileFilter:="All Files (*.*),*.*", _
                        MultiSelect:=True)
    'As mention Ron Rosenfeld, you need to use Multiselect

    'Since you want several files, you need a LOOP, a For Loop!
    For Each i In FileToOpen ' no matter if is 1 or many files you take, will work
        If FileToOpen = "False" Then Exit Sub 'But if you take no files will exit with no error
    'If FileToOpen <> False Then
        Set OpenBook = Application.Workbooks.Open(FileToOpen) 'the macro open the file
        Set A = OpenBook.ActiveSheet 'Store the active sheet inside A
        r = A.Range("A1").SpecialCells(xlCellTypeLastCell).Row 'Here look for the last cell, this is like
                                                               ' press the CTRL+END keys in the keyboard
                                                               'I asume your data in only en column A
                                                               'goto to the last cell and take the number of the row
        Set RngCopy = A.Range(Cells(1, 1), Cells(r, 1)) 'Take the whole range, and I asume you want to take
                                                        'From A1 to the last row, A1000 ej.
        'OpenBook.Sheets(1).Range("A:A").Copy
        B.Activate 'Go to rawdata!
        p = B.Range("A1000000").End(xlUp).Row + 1 'Here! From the very last cell.
                                                  'Notice: if you have Excel 97 and before, you need to change to
                                                  '65000, if not, 1000000 will work.
                                                  'From the A1000000 to the top, tell the row + 1
                                                  'Mean... one row bellow the last row in your data.

        Set RngPaste = B.Range(Cells(p, 1), Cells(p + r, 1)) 'Look Here!
                                                             'The last cell (last row + 1 = p) of your data in rawData plus
                                                             'The data you want to insert bellow that data.
                                                             'p + the count of the rows in the new data (r)
                                                             'p + r
                                                             'all this just in column A
        RngPaste.Value = RngCopy.Value
        'We don't use COPY, only if is necesary!
        'We transfer data from here to there!
        'Now we can tell B = A
        'B.Range("A1").PasteSpecial xlPasteValues
        OpenBook.Close False 'Good Boy!!!

        'it is good practice to clean your vars/objects
        Set OpenBook = Nothing
        Set A = Nothing
        Set B = Nothing
        Set RngCopy = Nothing
        Set RngPaste = Nothing
     'End If
    Next i
End Sub
