Reading Microsoft Word Document in JAVA

May 9th, 2008 Hitesh Agrawal Leave a comment Go to comments

When it comes to reading Microsoft Office Word document Java does not have any in build classes to handle this but Apache POI Package developed by Apache Foundation gives you the power of reading Microsoft Word document in Java. More information on the Apache POI package can be found at Apache POI

import org.apache.poi.poifs.filesystem.*;
import org.apache.poi.hwpf.*;
import org.apache.poi.hwpf.extractor.*;
import java.io.*;
 
public class readDoc
{
	public static void main( String[] args )
	{
		String filesname = "Hello.doc";
		POIFSFileSystem fs = null;
		try
		{
                  fs = new POIFSFileSystem(new FileInputStream(filesname; 
                  //Couldn't close the braces at the end as my site did not allow it to close
 
                  HWPFDocument doc = new HWPFDocument(fs);
 
		  WordExtractor we = new WordExtractor(doc);
 
		  String[] paragraphs = we.getParagraphText();
 
		  System.out.println( "Word Document has " + paragraphs.length + " paragraphs" );
		  for( int i=0; i<paragraphs .length; i++ ) {
			paragraphs[i] = paragraphs[i].replaceAll("\\cM?\r?\n","");
                	System.out.println( "Length:"+paragraphs[ i ].length());
		  }
                }
                catch(Exception e) { 
                    e.printStackTrace();
                }
         }
}

Code Explanation:

Creating new POIFSFileSystem Object and passing the Microsoft Word document to it
Creating new object of HWPFDocument class, this class is specifically responsible for handling Microsoft Word Document
WordExtractor will extract all the words from the word document
getParagraphText() will extract all the text paragraph wise
Finally we try to read the paragraph content

  Hi Slim,
  Just place the hello.doc where .class file resides. If you are putting the doc file at another location than specify the location path in the source code. IT will work fine.
  
  Thanks,

Hi friends,

I am trying to change the font size of a text.
To do this I am writing one HWPF stream to another and hence can change the font, but what I exactly need is to have different font(and/or size) for each word/paragraph. Basically to have more than one font size in a single piece of word file.
Can anybody please tell me how to go about doing this ??

  Hi UJJAL,
  You will have to add Apache POI libraries in your class path to make it work. You can download the Apache POI packages from http://poi.apache.org/ and also you are trying to read microsoft word documents in java than you will also require this libraries as well. http://poi.apache.org/hwpf/index.html
  
  Thanks,

I think there are a lot of serious bugs in the implementation of HWPF format, e.g. the following:

HWPFDocument doc = new HWPFDocument(inputStream);
doc.write(outputStream);

turns .doc files into somethig that cannot be opened with Word anymore.
