使用VBA将多个Excel工作簿从特定文件夹导入到单个工作表中

当您开始使用VBA时，我建议您在模块顶部使用OptionExplicit，它将强制您声明所有变量

另一方面，当您将Dim Path、FName等变量声明为字符串时，FName将是字符串，Path将是变量类型

为工作簿和工作表对象使用变量将有助于清理代码

此外，缩进将有助于代码的可读性

Sub MergeExcels()

Dim Path, FName As String

Path = ""
FName = Dir(Path & "*.xlsx")

    Do While File <> ""
    Workbooks.Open File = Path & FName, ReadOnly:=True
    For Each Sheet In ActiveWorkbook.Sheets
    Sheet.Copy After:=ThisWorkbook.Sheets(1)
    Next Sheet
    Workbooks(File).Close
    File = Dir()
    Loop

End Sub

---

编辑：发现错误，您给了FName文件名，但正在浏览始终为空的文件名。

将文件夹中的多个Excel文件合并到一张工作表中：

Option Explicit
Sub MergeExcels()

    Dim Path As String, FName As String
    Dim wb As Workbook
    Dim ws As Worksheet

    Path = ""
    FName = Dir(Path & "*.xlsx")
    With ThisWorkbook
        Do While FName <> ""
            Set wb = Workbooks.Open(Path & FName, ReadOnly:=True)
            For Each ws In wb.Worksheets
                ws.Copy After:=.Sheets(.Sheets.Count)
            Next ws
            wb.Close SaveChanges:=False
            FName = Dir()
        Loop
    End With

End Sub

它抛出了什么错误？没有一个编译错误，但是值doesnotfetchingis my code right您的代码正在打开工作簿，将每个工作表复制到主工作簿的第二个索引位置。它可以被清除，但这应该是工作。你能给我一个更好的解决方案来运行这个代码这么多。。。但是收到编译错误我刚刚编辑了代码，请再试一次，如果它一直给你一个错误，请指出你的代码在哪一行突出显示。你是否像我的例子一样复制了代码？因为您缺少一些文本。
