Hey M2,
Not sure if this helps, but I use SharePoint as a means to get a DOCX file in another format (in this case, tho, it is PDF).
This works great if you want to use DOCX files as sources for vector embeddings - you convert them to PDF then import them. See my article here: DOCX ingestion to vector database (PgVector) - Tips & Tricks - n8n Community
I’ve not come across a way to programatically ‘handle’ DOCX natively and be able to create or edit them.
Rgds
