• PageSplitter

Split a Word DOCX using Java

First of all, let’s have a look at how to split an MS Word document by page. In this case, each page of the source document will be converted into a separate Word document. The following are the steps to split pages of a Word document.

• Load the Word document using Document class.
• Create an object of DocumentPageSplitter and initialize it with the Document object.
• Loop through the pages in the document.
• Use DocumentPageSplitter.getDocumentOfPage(Int pageIndex) method to retrive each page into a Document object.
• Save the document using the Document.save(String) method.

The following code sample shows how to split a Word document using Java.

Use Page Range to Split Word DOCX in Java

You can also define a page range that you want to split from the source Word document. The following are the steps to perform this operation.

• Load the Word document using Document class.
• Create an object of DocumentPageSplitter and initialize it with the Document object.
• Use DocumentPageSplitter.getDocumentOfPageRange(Int, Int) method to retrive collection of pages into a Document object.
• Save the document using the Document.save(String) method.

The following code sample shows how to split a Word document by a page range using Java.

Split a Word Document by Sections using Java

Aspose.Words for Java also allows you to split a Word document by section breaks. The following are the steps to perform this operation.

• Load the Word document using Document class.
• Loop through each section of the document using Document.getSections() method.
• Clone section into a Section object using Document.getSections().get(index).deepClone() method.
• Create a new Document and add cloned section to the document using Document.getSections().add(Section) method.
• Save the document using Document.save(String) method.

The following code sample shows how to split a Word document by sections using Java.
