Python Method Splits Word Documents by Page Range or Section Breaks

Splitting a long Word document into separate files is a common need, such as dividing a report by chapter or extracting a specific page range. The article notes that python-docx handles paragraphs well but cannot directly access rendered page information, whereas Spire.Doc for Python can read page layout and section structure. It describes two strategies: extracting a range of rendered pages with the ExtractPages method, and saving each section, defined by section breaks, as its own file. Spire.Doc is installed via pip and does not require Microsoft Word on the runtime system. The article warns that page-based splitting depends on final typesetting, so changes to fonts, images, or margins can alter pagination.
