VBA判断工作簿是否打开、创建工作簿、创建工作表

Function IsWorkbookOpen(FileName As String) As Boolean
    Dim wb As Workbook
    On Error Resume Next
    Set wb = Workbooks(FileName)
    On Error GoTo 0
    If Not wb Is Nothing Then
        IsWorkbookOpen = True
    Else
        IsWorkbookOpen = False
    End If
End Function



sub test()

'获取当前目录路径
    currentPath = ThisWorkbook.Path & "\"
    Set fso = CreateObject("Scripting.FileSystemObject")
    ' 获取当前目录
    Set folder = fso.GetFolder(currentPath)
    ' 遍历当前目录下的所有文件
    For Each file In folder.Files
        ' 获取文件名和扩展名
        FileName = fso.GetFileName(file.Path)
        fileExtension = fso.GetExtensionName(file.Path)
        ' 判断文件扩展名是否为xls或xlsx，且不包含xlsm
        If (fileExtension = "xls" Or fileExtension = "xlsx") And fileExtension <> "xlsm" Then
            '打开工作簿
            Set wb = Workbooks.Open(currentPath & FileName)
            ' 如果该工作簿已打开，则保存并关闭
            If IsWorkbookOpen(FileName) Then
                wb.Save
                wb.Close
