If you search for “Word template” in the Mendix Marketplace you find some possible (paid) solutions.
Please use my Word Exporter module from the Marketplace. It is a fully configured test project which you can use for importing a template prefilled Word Document. The app will populate the word document with possibly all kinds of typical Word stuff but based on the contents in your Mendix app. Replacing words, adding tables, rich text and images are supported. Even line and bar charts are supported as well.
It is free of charge. One downside, it can’t handle PDF. Pure Word.
