我正在尝试使用VBA编码 - 这是我很新的 - 从PDF(不是图像)获取一系列.doc文档,也就是说,我试图循环各种PDF文件并将它们保存在MS Word中格式.我的经验是,这个单词很好地读取了我所拥有的PDF文档:word大部分时间都保持了PDF文件的正确布局.我不确定这是否是解决这个问题的正确选择,我要求另一个建议 - 如果可能的话,使用R.
无论如何,这里是我在这里找到的代码:
Sub convertToWord()
Dim MyObj As Object, MySource As Object, file As Variant
file = Dir("C:\Users\username\work_dir_example" & "*.pdf") 'pdf path
Do While (file <> "")
ChangeFileOpenDirectory "C:\Users\username\work_dir_example"
Documents.Open Filename:=file, ConfirmConversions:=False, ReadOnly:= _
False, AddToRecentFiles:=False, PasswordDocument:="", PasswordTemplate:= _
"", Revert:=False, WritePasswordDocument:="", WritePasswordTemplate:="", _
Format:=wdOpenFormatAuto, XMLTransform:=""
ChangeFileOpenDirectory "C:\Users\username\work_dir_example"
ActiveDocument.SaveAs2 Filename:=Replace(file, ".pdf", ".docx"), FileFormat:=wdFormatXMLDocument _
, LockComments:=False, Password:="", AddToRecentFiles:=True, _
WritePassword:="", ReadOnlyRecommended:=False, EmbedTrueTypeFonts:=False, _
SaveNativePictureFormat:=False, SaveFormsData:=False, SaveAsAOCELetter:= _
False, CompatibilityMode:=15
ActiveDocument.Close
file = Dir
Loop
End Sub

在开发人员的窗口中粘贴之后,我将代码保存在模块中 - >我关闭开发人员的窗口 - >我点击"宏"按钮 - >我执行"convertToWord"宏.我在弹出框中收到以下错误:"Sub或Function not defined".我该如何解决?此外,之前由于某些原因我现在还不清楚,我得到了一个与函数相关的错误ChangeFileOpenDirectory,似乎也没有定义.

我将代码更改为以下内容:
Sub convertToWord()
Dim MyObj As Object, MySource As Object, file As Variant
file = Dir("C:\Users\username\work_dir_example" & "*.pdf")
ChDir "C:\Users\username\work_dir_example"
Do While (file <> "")
Documents.Open Filename:=file, ConfirmConversions:=False, ReadOnly:= _
False, AddToRecentFiles:=False, PasswordDocument:="", PasswordTemplate:= _
"", Revert:=False, WritePasswordDocument:="", WritePasswordTemplate:="", _
Format:=wdOpenFormatAuto, XMLTransform:=""
ActiveDocument.SaveAs2 Filename:=Replace(file, ".pdf", ".docx"), FileFormat:=wdFormatXMLDocument _
, LockComments:=False, Password:="", AddToRecentFiles:=True, _
WritePassword:="", ReadOnlyRecommended:=False, EmbedTrueTypeFonts:=False, _
SaveNativePictureFormat:=False, SaveFormsData:=False, SaveAsAOCELetter:= _
False, CompatibilityMode:=15
ActiveDocument.Close
file = Dir
Loop
End Sub

现在我没有在弹出框中收到任何错误消息,但我的工作目录中没有输出.现在可能出现什么问题?
可以读取PDF文件和编写Word文档(XML)的任何语言都可以做到这一点,但是您想要的转换(打开PDF时Word会执行此操作)将需要为应用程序本身使用API。VBA是您轻松的选择。
您发布的代码片段(以及下面的示例)使用早期绑定和枚举常量,这意味着我们需要对Word对象库的引用。已经为您在Word文档中编写的任何代码进行了设置,因此请创建一个新的Word文档,并将该代码添加到标准模块中。(如果需要更多详细信息,请参阅此Excel教程,我们的过程步骤相同)。
您可以从VB编辑器(使用“运行”按钮)或普通文档窗口(在Word 2010-2016中的“视图”选项卡上单击“宏”按钮)运行宏。如果要重复使用宏而无需再次设置代码,则将文档另存为DOCM文件。
现在获取代码!
如注释中所述,如果仅确保文件夹路径以反斜杠“ \”字符结尾,则第二个片段有效。修复该问题后,它仍然不是很好的代码,但这可以使您正常运行。
我假设您想加倍努力,并有一个写得很好的版本,可以在以后重新使用或扩展。为简单起见,我们将使用两个过程:主转换和禁止显示PDF转换警告对话框的过程(由注册表控制)。
主要程序:

'Append file type with wildcard

'Get path for first PDF (blank string if no PDFs exist)
file = Dir(file)
originalAlertLevel = Application.DisplayAlerts
Application.DisplayAlerts = wdAlertsNone
If file <> "" Then regValPDF = TogglePDFWarning(1)

file = Dir
Loop
CleanUp:
On Error Resume Next 'Ignore errors during cleanup
doc.Close False
'Restore registry value, if necessary

注册表设置功能:
Private Function TogglePDFWarning(newVal As Integer) As Integer
'This function reads and writes the registry value that controls
'the dialog displayed when Word opens (and converts) a PDF file

Dim regKey As String
Dim regVal As Variant
'setup shell object and string for key
