文章背景：测试仪器的数据有些会以Excel文件的形式保存，有时需要将测试数据转化为pdf格式。通过虚拟打印机（Adobe PDF）可以将excel文件输出为pdf文件。然而，当文件比较多时，这种操作比较费时。现在以批量转化Excel文件（.xlsx格式）为例，采用VBA编程，进行任务的实现。

在批量转化文件的按钮中指定的宏命令为ConvertFiles。

在模块中添加的代码如下：

Option Explicit

Sub ConvertFiles()

    '批量转化Excel文件为pdf
    Dim filefolder As String
    
    Dim fd As FileDialog, t As String, str As String, name As String
    
    Application.ScreenUpdating = False
    
    '获取默认路径
    ChDrive ThisWorkbook.Worksheets("Sheet1").Range("B2").Value
    ChDir ThisWorkbook.Worksheets("Sheet1").Range("B3").Value
    
    '1 创建储存pdf文件的空文件夹
    filefolder = ThisWorkbook.Worksheets("Sheet1").Range("B3").Value & "\pdf文件"
    
    If Not isDirectory(filefolder) Then
    
        VBA.MkDir (filefolder)
        
    Else
    
        MsgBox "默认路径的pdf文件夹已存在，请确认！"
        
        Exit Sub
    
    End If
    
    '2 选择需要转化的文件夹路径
    Set fd = Application.FileDialog(msoFileDialogFolderPicker)
    
    With fd
    
        If .Show = -1 Then
        
            t = .SelectedItems(1)
            
        Else
        
            MsgBox "未选取文件夹！"
            
            Exit Sub
            
        End If
    
    End With
    
    str = Dir(t & "\*.xlsx")   ' 开始查找文件，格式为xlsx文件
    Do While Len(str) > 0
    
        Workbooks.Open (t & "\" & str)
        
        name = CreateObject("Scripting.FileSystemobject").getextensionname(str)  '获取文件的扩展名
        
        ActiveWorkbook.Worksheets(1).ExportAsFixedFormat Type:=xlTypePDF, _
            Filename:=filefolder & "\" & Replace(str, name, "pdf"), Quality:=xlQualityStandard, _
            IgnorePrintAreas:=False, OpenAfterPublish:=False
            
        Workbooks(str).Close False
        
        str = Dir()
        
    Loop
    
    MsgBox "Done!"
    
    Application.ScreenUpdating = False
    
    Exit Sub

End Sub

Function isDirectory(pathName As String) As Boolean

    '用于判断文件夹是否存在
    
    Dim fso As Object
    
    Set fso = CreateObject("Scripting.FileSystemObject")
    
    isDirectory = fso.FolderExists(pathName)

End Function
