[英]Open workbooks in a folder and subfolders and update each
我在 Ecel 中运行以下 VBA 来打开一个文件夹,然后更新该文件夹中的所有 Excel 工作表。 但是我希望它也包含所有子文件夹。
Sub AllWorkbooks()
Dim MyFolder As String 'Path collected from the folder picker dialog
Dim MyFile As String 'Filename obtained by DIR function
Dim wbk As Workbook 'Used to loop through each workbook
On Error Resume Next
Application.ScreenUpdating = False
'Opens the folder picker dialog to allow user selection
With Application.FileDialog(msoFileDialogFolderPicker)
.Title = "Please select a folder"
.Show
.AllowMultiSelect = False
If .SelectedItems.Count = 0 Then 'If no folder is selected, abort
MsgBox "You did not select a folder"
Exit Sub
End If
MyFolder = .SelectedItems(1) & "\" 'Assign selected folder to MyFolder
End With
MyFile = Dir(MyFolder) 'DIR gets the first file of the folder
'Loop through all files in a folder until DIR cannot find anymore
Do While MyFile <> “”
'Opens the file and assigns to the wbk variable for future use
Set wbk = Workbooks.Open(Filename:=MyFolder & MyFile)
'Replace the line below with the statements you would want your macro to perform
ActiveWorkbook.RefreshAll
Application.Wait (Now + TimeValue("0:00:05"))
wbk.Close savechanges:=True
MyFile = Dir 'DIR gets the next file in the folder
Loop
Application.ScreenUpdating = True
End Sub
好的,您需要使用 FileSystemObject 并在 Tools->References 中添加对 Windows Script Host Object Model 的引用。 然后试试下面的代码。
Sub AllWorkbooks()
Dim MyFolder As String 'Path collected from the folder picker dialog
Dim MyFile As String 'Filename obtained by DIR function
Dim wbk As Workbook 'Used to loop through each workbook
Dim FSO As New FileSystemObject ' Requires "Windows Script Host Object Model" in Tools -> References
Dim ParentFolder As Object, ChildFolder As Object
On Error Resume Next
Application.ScreenUpdating = False
'Opens the folder picker dialog to allow user selection
With Application.FileDialog(msoFileDialogFolderPicker)
.Title = "Please select a folder"
.Show
.AllowMultiSelect = False
If .SelectedItems.Count = 0 Then 'If no folder is selected, abort
MsgBox "You did not select a folder"
Exit Sub
End If
MyFolder = .SelectedItems(1) & "\" 'Assign selected folder to MyFolder
End With
MyFile = Dir(MyFolder) 'DIR gets the first file of the folder
'Loop through all files in a folder until DIR cannot find anymore
Do While MyFile <> ""
'Opens the file and assigns to the wbk variable for future use
Set wbk = Workbooks.Open(Filename:=MyFolder & MyFile)
'Replace the line below with the statements you would want your macro to perform
ActiveWorkbook.RefreshAll
Application.Wait (Now + TimeValue("0:00:05"))
wbk.Close savechanges:=True
MyFile = Dir 'DIR gets the next file in the folder
Loop
For Each ChildFolder In FSO.GetFolder(MyFolder).SubFolders
MyFile = Dir(MyFolder & ChildFolder.Name) 'DIR gets the first file of the folder
'Loop through all files in a folder until DIR cannot find anymore
Do While MyFile <> ""
'Opens the file and assigns to the wbk variable for future use
Set wbk = Workbooks.Open(Filename:=MyFolder & ChildFolder.Name & "\" & MyFile)
'Replace the line below with the statements you would want your macro to perform
ActiveWorkbook.RefreshAll
Application.Wait (Now + TimeValue("0:00:05"))
wbk.Close savechanges:=True
MyFile = Dir 'DIR gets the next file in the folder
Loop
Next ChildFolder
Application.ScreenUpdating = True
End Sub
或者,您可以只使用 CMD 并读取输出,这样可以更快地向下钻取子文件夹。
我已经使用".xl*"
作为文件过滤器(我假设你只想要 Excel 文件?)但根据你的需要进行更改:
Sub MM()
Const startFolder As String = "C:\Users\MacroMan\Folders\" '// note trailing '\'
Dim file As Variant, wb As Excel.Workbook
For Each file In Filter(Split(CreateObject("WScript.Shell").Exec("CMD /C DIR """ & startFolder & "*.xl*"" /S /B /A:-D").StdOut.ReadAll, vbCrLf), ".")
Set wb = Workbooks.Open(file)
'// Do what you want here with the workbook
wb.Close SaveChanges:=True '// or false...
Set wb = Nothing
Next
End Sub
