Does Dify have a workflow or plugin to convert Word (doc and docx) to PDF or directly parse Word (doc and docx)?

Yes, there are. File conversion can be done using Markdown Exporter; as for content parsing, you can solve it with the built-in nodes’ doc extractor. If your PDF is an image version, you can try Unstructured Plugin and also search for OCR plugins such as: OCR recognition service.
