'读取Excel行和列信息

MaxRow = DoXLSX.GetRowTotal

MaxCol = DoXLSX.GetColumnCount

If MaxRow = 0 Or MaxCol = 0 Then

DoXLSX.Close

Set DoXLSX = Nothing

MsgBox "没有数据！"

Exit Sub

End If

'读取修改前的数据

Data_Before = ""

For i = 1 To MaxRow

If i > 1 Then Data_Before = Data_Before & vbCrLf

For j = 1 To MaxCol

If j > 1 Then Data_Before = Data_Before & vbTab

Data_Before = Data_Before & DoXLSX.Rs(j, i)

Next

Next

'修改数据

DoXLSX.SetCellValue 1, 1, "你好AAA"

DoXLSX.SetCellValue 2, 2, 12.25

DoXLSX.SetCellValue 1, 3, 12.25
