Split Word Documents into Multiple Files in Python

In certain cases, you need to split large Word documents into smaller ones. You can split a Word document by pages, sections, or columns. In this article, you will learn how to split a Word document into multiple files using Python. The step‑by‑step guide and code samples demonstrate how to split a Word document by sections, pages, or page ranges programmatically.

Python Library to Split MS Word Documents

To split a DOCX or DOC document into multiple files, we will use Aspose.Words for Python. It is a word‑processing library that creates and manipulates Word documents. Install it from PyPI with the following command.

pip install aspose-words

Split a Word Document by Sections in Python

Most Word files are divided into sections using section breaks. To save each section as a separate file, follow these steps:

  • Load the document with the Document class.
  • Loop through each section in Document.sections.
  • For each section:
    • Create a new Document object.
    • Clear its default sections using Document.sections.clear().
    • Import the current section with Document.import_node(Section, True).as_section() and store the returned Section.
    • Add the imported Section to the new document’s sections collection.
    • Save the new document as a DOCX file using Document.save(string).

The code sample below shows how to split a Word document by sections in Python.

Splitting a Word Document by Pages in Python

To split each page of a document and save it as an individual DOCX file, use these steps:

  • Load the document with the Document class.
  • Retrieve the total page count via Document.page_count.
  • Loop from the first to the last page and for each iteration:
    • Extract the page using Document.extract_pages(pageIndex, 1).
    • Save the extracted page as a DOCX file with Document.save(string).

The following code sample demonstrates page‑by‑page splitting.

Split a Word Document by a Page Range in Python

You can also extract a specific range of pages and save it as a separate file. Follow these steps:

  • Load the document with the Document class.
  • Call Document.extract_pages(startIndex, pageCount) where startIndex is the first page number and pageCount is the number of pages to extract.
  • Save the extracted range as a DOCX file using Document.save(string).

The code sample below shows how to extract a page range and save it.
