Java byteArray[] to docx


doc file in byte[] type. Is it possible to convert it from byte[] into .docx file.

tried just change file extension programilly but it does not work. any suggestions?

I generate report using BiRT eclipse code of saving doc:

options = new RenderOptionBase(); ByteArrayOutputStream bos = new ByteArrayOutputStream(); options.setOutputStream(bos); options.setOutputFormat("doc"); if(parameters != null){ task.setParameterValues(parameters); } task.setRenderOption(options); task.run(); return bos.toByteArray() //IRunAndRenderTask task;

problem is that we use BIRT 3.7 which not support DocxRenderOption


Take a look at Aspose.Words for Java -- <a href="http://www.aspose.com/java/word-component.aspx" rel="nofollow">http://www.aspose.com/java/word-component.aspx</a>

It has really good doc too -- <a href="http://www.aspose.com/docs/display/wordsjava/load+or+create+a+document" rel="nofollow">http://www.aspose.com/docs/display/wordsjava/load+or+create+a+document</a>

Code will be as simple as

// Open a document.

Document doc = new Document("input.doc");

// Save document.


Step1: save the doc file Step2: using this lib convert the file and save as docx file.
