这里有一个VBA解决方案（我不知道如何使用Python来实现）。
如果您需要将多个Word文件转换为其他格式，如TXT，RTF，HTML或PDF，请运行下面的脚本。

Option Explicit On

Sub ChangeDocsToTxtOrRTFOrHTML()
    'with export to PDF in Word 2007
    Dim fs As Object
    Dim oFolder As Object
    Dim tFolder As Object
    Dim oFile As Object
    Dim strDocName As String
    Dim intPos As Integer
    Dim locFolder As String
    Dim fileType As String
    On Error Resume Next

    locFolder = InputBox("Enter the folder path to DOCs", "File Conversion", "C:\Users\your_path_here\")
    Select Case Application.Version
        Case Is < 12
            Do
                fileType = UCase(InputBox("Change DOC to TXT, RTF, HTML", "File Conversion", "TXT"))
            Loop Until (fileType = "TXT" Or fileType = "RTF" Or fileType = "HTML")
        Case Is >= 12
            Do
                fileType = UCase(InputBox("Change DOC to TXT, RTF, HTML or PDF(2007+ only)", "File Conversion", "TXT"))
            Loop Until (fileType = "TXT" Or fileType = "RTF" Or fileType = "HTML" Or fileType = "PDF")
    End Select

    Application.ScreenUpdating = False
    Set fs = CreateObject("Scripting.FileSystemObject")
    Set oFolder = fs.GetFolder(locFolder)
    Set tFolder = fs.CreateFolder(locFolder & "Converted")
    Set tFolder = fs.GetFolder(locFolder & "Converted")

    For Each oFile In oFolder.Files
        Dim d As Document
        Set d = Application.Documents.Open(oFile.Path)
        strDocName = ActiveDocument.Name
        intPos = InStrRev(strDocName, ".")
        strDocName = Left(strDocName, intPos - 1)
        ChangeFileOpenDirectory tFolder
        Select Case fileType
            Case Is = "TXT"
                strDocName = strDocName & ".txt"
                ActiveDocument.SaveAs FileName:=strDocName, FileFormat:=wdFormatText
        Case Is = "RTF"
                strDocName = strDocName & ".rtf"
                ActiveDocument.SaveAs FileName:=strDocName, FileFormat:=wdFormatRTF
        Case Is = "HTML"
                strDocName = strDocName & ".html"
                ActiveDocument.SaveAs FileName:=strDocName, FileFormat:=wdFormatFilteredHTML
        Case Is = "PDF"
                strDocName = strDocName & ".pdf"
                ActiveDocument.ExportAsFixedFormat OutputFileName:=strDocName, ExportFormat:=wdExportFormatPDF
        End Select
        d.Close
        ChangeFileOpenDirectory oFolder
    Next oFile
    Application.ScreenUpdating = True

End Sub

您可以使用Aspose. Words Cloud SDK for Python。它支持DOC/DOCX到PDF的转换，并保持格式/样式不变。它的免费试用计划提供每月150次API调用。
