Convert DOC file to DOCX with Java

I need to use DOCX files (actually the XML contained in them) in a Java software I'm currently developing, but some people in my company still use the DOC forma开发者_开发百科t.

Do you know if there is a way to convert a DOC file to the DOCX format using Java ? I know it's possible using C#, but that's not an option

I googled it, but nothing came up...

Thanks

You may try Aspose.Words for Java. It allows you to load a DOC file and save it as DOCX format. The code is very simple as shown below:

// Open a document.  
Document doc = new Document("input.doc"); 
// Save document. 
doc.save("output.docx");

Please see if this helps in your scenario.

Disclosure: I work as developer evangelist at Aspose.

Check out JODConverter to see if it fits the bill. I haven't personally used it.

Use newer versions of jars jodconverter-core-4.2.2.jar and jodconverter-local-4.2.2.jar

String inputFile = "*.doc";
String outputFile = "*.docx";

LocalOfficeManager localOfficeManager = LocalOfficeManager.builder()
            .install()
            .officeHome(getDefaultOfficeHome()) //your path to openoffice
            .build();

  try {
      localOfficeManager.start();
      final DocumentFormat format
              = DocumentFormat.builder()
                      .from(DefaultDocumentFormatRegistry.DOCX)
                      .build();

      LocalConverter
              .make()
              .convert(new FileInputStream(new File(inputFile)))
              .as(DefaultDocumentFormatRegistry.getFormatByMediaType("application/msword"))
              .to(new File(outputFile))
              .as(format)
              .execute();

  } catch (OfficeException ex) {
      Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
  } catch (FileNotFoundException ex) {
      Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
  } finally {
      OfficeUtils.stopQuietly(localOfficeManager);
  }

JODConvertor calls OpenOffice/LibreOffice via a network protocol. It can therefore 'do anything you can do in OpenOffice'. This includes converting formats. But it only does as good a job as whatever version of OpenOffice you are running. I have some art in one of my docs, and it doesn't convert them as I hoped.

JODConvertor is no longer supported, according to the google code web site for v3.

To get JOD to do the job you need to do something like

private static void transformBinaryWordDocToDocX(File in, File out)
{
    OfficeDocumentConverter converter = new OfficeDocumentConverter(officeManager);
    DocumentFormat docx = converter.getFormatRegistry().getFormatByExtension("docx");
    docx.setStoreProperties(DocumentFamily.TEXT,
    Collections.singletonMap("FilterName", "MS Word 2007 XML"));

    converter.convert(in, out, docx);
}


private static void transformBinaryWordDocToW2003Xml(File in, File out)
{
    OfficeDocumentConverter converter = new OfficeDocumentConverter(officeManager);;
    DocumentFormat w2003xml = new DocumentFormat("Microsoft Word 2003 XML", "xml", "text/xml");
    w2003xml.setInputFamily(DocumentFamily.TEXT);
    w2003xml.setStoreProperties(DocumentFamily.TEXT, Collections.singletonMap("FilterName", "MS Word 2003 XML"));
    converter.convert(in, out, w2003xml);
}



private static OfficeManager officeManager;

@BeforeClass
public static void setupStatic() throws IOException {

          /*officeManager = new DefaultOfficeManagerConfiguration()
      .setOfficeHome("C:/Program Files/LibreOffice 3.6")
      .buildOfficeManager();
      */

    officeManager = new ExternalOfficeManagerConfiguration().setConnectOnStart(true).setPortNumber(8100).buildOfficeManager();


    officeManager.start();
}

@AfterClass
public static void shutdownStatic() throws IOException {

    officeManager.stop();
}

For this to work you need to be running LibreOffice as a networked server ( I could not get the 'run on demand' part of JODConvertor to work under windows with LO 3.6 very well )

To convert DOC file to HTML look at this (Convert Word doc to HTML programmatically in Java)

Use this: http://poi.apache.org/

Or use this :

XWPFDocument docx = new XWPFDocument(OPCPackage.openOrCreate(new File("hello.docx")));  
XWPFWordExtractor wx = new XWPFWordExtractor(docx);  
String text = wx.getText();  
System.out.println("text = "+text); 

I needed the same conversion ,after researching a lot found Jodconvertor can be useful in it , you can download the jar from https://code.google.com/p/jodconverter/downloads/list

Add jodconverter-core-3.0-beta-4-sources.jar file to your project lib

  //1) Create OfficeManger Object     
OfficeManager officeManager = new DefaultOfficeManagerConfiguration()
                .setOfficeHome(new File("/opt/libreoffice4.4"))
                .buildOfficeManager();
        officeManager.start();
    // 2) Create JODConverter converter   
        OfficeDocumentConverter converter = new OfficeDocumentConverter(
                officeManager);
// 3)Create DocumentFormat for docx
DocumentFormat docx = converter.getFormatRegistry().getFormatByExtension("docx");
        docx.setStoreProperties(DocumentFamily.TEXT,
                Collections.singletonMap("FilterName", "MS Word 2007 XML"));
//4)Call convert funtion in converter object
converter.convert(new File("doc/AdvancedTable.doc"), new File(
                "docx/AdvancedTable.docx"), docx);
