在论坛上看到有网友问到如何把多个数据同时导出追加到同到Excel中。这里写了几个函数。复制到宏命令代码里面，执行宏即可实现。
功能：遍历用户指定的文件夹，把文件夹中所有的excel文件的第一个表格的数据复制到本excel文件中。注意，每个excel文件中有效数据行的判断标准是A列的最后一个有数据的单元格的行号，比如A列到第10行结束，B列到第11行结束，那么程序将不会复制第11行。
效果图：
详细源码：
Sub combine()
Dim folder As String
Dim count As Integer
folder = ChooseFolder()
count = combineFiles(folder, "xls")
'count = count + combineFiles(folder, "xlsx")
End Sub
'整合文件
Function combineFiles(folder, appendix)
Dim MyFile As String
Dim s As String
Dim count, n, copiedlines As Integer
MyFile = Dir(folder & "\*." & appendix)
count = count + 1
n = 2
Do While MyFile <> ""
copiedlines = CopyFile(folder & "\" & MyFile, 2, n)
If copiedlines > 0 Then
n = n + copiedlines
count = count + 1
End If
MyFile = Dir
Loop
combineFiles = count
End Function
'复制数据
Function CopyFile(filename, srcStartLine, dstStartLine)
Dim book As Workbook
Dim sheet As Worksheet
Dim rc As Integer
CopyFile = 0
If filename = (ThisWorkbook.Path & "\" & ThisWorkbook.Name) Then
Exit Function
End If
Set book = Workbooks.Open(filename)
Set sheet = book.Sheets(1) '使用第一个sheet
rc = sheet.Range("A65536").End(xlUp).Row
If rc >= srcStartLine Then
sheet.Rows(srcStartLine & ":" & rc).copy ThisWorkbook.Sheets(1).Range("A" & dstStartLine) '复制到指定位置
CopyFile = rc - srcStartLine + 1
End If
book.Close
End Function
'选择文件夹
Function ChooseFolder() As String
Dim dlgOpen As FileDialog
Set dlgOpen = Application.FileDialog(msoFileDialogFolderPicker)
With dlgOpen
If .Show = -1 Then
ChooseFolder = .SelectedItems(1)
End If
End With
Set dlgOpen = Nothing
End Function参考至：oceanking（博客园）
