VBA使用最后一行区域将数据从一个工作簿复制到另一个工作簿

Sub CopyData()
    Dim sourceWorkbook As Workbook
    Dim destinationWorkbook As Workbook
    Dim sourceWorksheet As Worksheet
    Dim destinationWorksheet As Worksheet
    Dim lastRow As Long
    
    ' 打开源工作簿和目标工作簿
    Set sourceWorkbook = Workbooks.Open("源工作簿路径")
    Set destinationWorkbook = Workbooks.Open("目标工作簿路径")
    
    ' 指定源工作表和目标工作表
    Set sourceWorksheet = sourceWorkbook.Worksheets("源工作表名称")
    Set destinationWorksheet = destinationWorkbook.Worksheets("目标工作表名称")
    
    ' 获取源工作表最后一行的行号
    lastRow = sourceWorksheet.Cells(sourceWorksheet.Rows.Count, 1).End(xlUp).Row
    
    ' 复制数据到目标工作表
    sourceWorksheet.Range("A1:D" & lastRow).Copy destinationWorksheet.Range("A1")
    
    ' 关闭工作簿
    sourceWorkbook.Close SaveChanges:=False
    destinationWorkbook.Close SaveChanges:=True
    
    ' 释放对象
    Set sourceWorksheet = Nothing
    Set destinationWorksheet = Nothing
    Set sourceWorkbook = Nothing
    Set destinationWorkbook = Nothing
End Sub
