i believe its a zip and inside it have xml files.
rename it to .docx.zip and you can open it at pc (same for xlsx excel)

i have´nt seen a library for this.
You need to search the forum for any library available.

You can read it using jPOI library and a bit of inline code and javaobject library.

…
 asJO(Me).RunMethod("readDocxFile",Array("C:/temp/test.docx"))
End Sub
Sub asJO(o As JavaObject)As JavaObject
 Return o
End Sub
#if java
import java.io.File;
import java.io.FileInputStream;
import java.util.List;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
public static void readDocxFile(String fName) {
    try {
        File file = new File(fName);
        FileInputStream fis = new FileInputStream(file.getAbsolutePath());
        XWPFDocument document = new XWPFDocument(fis);
        List<XWPFParagraph> paragraphs = document.getParagraphs();

        for (XWPFParagraph para : paragraphs) {
            System.out.println(para.getText());
        }
        fis.close();
    } catch (Exception e) {
        e.printStackTrace();
    }
}
#End If

Sorry, I didn't catch it.
What do you mean?

public static void readDocxFile(String fName) {
    try {
        File file = new File(fName);
        FileInputStream fis = new FileInputStream(file.getAbsolutePath());
        XWPFDocument document = new XWPFDocument(fis);
        List<XWPFParagraph> paragraphs = document.getParagraphs();

        for (XWPFParagraph para : paragraphs) {
            System.out.println(para.getText());
        }
        fis.close();
    } catch (Exception e) {
        e.printStackTrace();
    }
}
#End If

Ok, it seems to be working fine.
What next?
I mean, to read the text, what should I do?

You can change the inline code to return the text if you want.

public static String readDocxFile(String fName) {
String rep = "";   
try {
        File file = new File(fName);
        FileInputStream fis = new FileInputStream(file.getAbsolutePath());
        XWPFDocument document = new XWPFDocument(fis);
        List<XWPFParagraph> paragraphs = document.getParagraphs();

        for (XWPFParagraph para : paragraphs) {
            //System.out.println(para.getText());
            rep += para.getText()+"\n";
        }
        fis.close();
    } catch (Exception e) {
        e.printStackTrace();
    }
    return rep;
}

Then call it with

Dim docText as String = asJO(Me).RunMethod("readDocxFile",array("path to the file"))

docText will contain the text of the document.

 

[Marco Gioia]

You are right!

        for (XWPFParagraph para : paragraphs) {
            System.out.println(para.getText());

I thought it was only to open it

Thanks
