使用 VBA 将多个 CSV 文件导入 Excel 中的多个工作表

Question

我正在创建一个 VBA/宏，将 2 个 CSV 文件从特定文件夹导入到我创建的 Excel 模板中的 2 个工作表中。

更具体地说，这些文件每天都会创建并保存为新工作簿（每天将两个新文件添加到文件夹中）所以我的问题是如何编写宏以始终导入 2 个最新文件？

请参阅下面的代码，我从中手动选择并使用宏导入最新文件。但是，重新运行宏不起作用，因为它显示“运行时错误'5' - 无效的过程调用或参数”。非常感谢您的帮助。

您可以通过这种方式找到最新的文件：

编辑：Dir 仅返回文件名，因此您也需要附加路径。

EDIT2：根据用户要求插入一些 Debug.Print。

Sub main()
    Dim s1 as String, s2 as String

    s1 = LastFile("P:\APS\Reports_From_PDP\AP_PDP_VehicleLoad_Report_AM")
    Debug.Print "Last file1: " & s1
    s2 = LastFile("P:\APS\Reports_From_PDP\AP_PDP_VehicleLoad_Report_PM")
    Debug.Print "Last file2: " & s2
End Sub
Function LastFile(sName as String) as String
    Dim dLatest as Date
    Dim dFound as Date      ' date of one matching filename
    Dim sLatest as string   ' the latest file or ""
    Dim sFound as string    ' one matching filename
    Dim sPath as string

    dLatest = 0
    sLatest = vbnullstring
    sPath = Left$(sName,  InStrRev(sName, "\"))

    sFound = Dir(sName & "*.csv")
    Do While sFound <> vbnullstring
         Debug.Print "Found: " & sFound
         dFound = FileDateTime(sPath & sFound)
         If dFound > dLatest Then 
             dLatest = dFound
             sLatest = sFound
         Endif
         sFound = Dir
    Loop
    LastFile = sLatest
End Function
