一、打开Excel
  Dim ExcelApp As Excel.Application
  Dim ExcelBook As Excel.Workbook
  Dim ExcelSheet As Excel.Worksheet
  Set ExcelApp = CreateObject("Excel.Application")
  Set ExcelBook = ExcelApp.Workbooks.Add
  ExcelFilePath = Application.ActivePresentation.Path & "\" & "ExcelFileName"
  '使用相对路径要比绝对路径好
  ExcelApp.Workbooks.Open ExcelFilePath, ReadOnly:=False
  Set ExcelBook = ExcelApp.Workbooks("ExcelFileName")
  Set ExcelSheet = Excel.Worksheets(n)
  '(n=1...工作表)
  二、关闭Excel
  If Not (ExcelBook Is Nothing) Then ExcelBook.Close
  If Not (ExcelApp Is Nothing) Then ExcelApp.Quit
  Set ExcelBook = Nothing
  Set ExcelSheet = Nothing
  Set ExcelApp = Nothing
