Automate Word snippets

[PHbench]

I want to use MS Word to write paragraphs/snippets/parts and store them with all the word formatting. I later would want to merge them into one Word document. I have used the docxtpl libraries to merge external data into a Word file. I understand this well. However, I do not know how to store (export) the data out of Word to use later. My goal is to organize and manage the paragraphs/snippets/parts with an external database application (FileMaker). After organing them I will combine them into a document that keeps the Word formatting when combined. I welcome any ideas or suggestions. Thank You
