I'm building a similar project, and I may open-source it. I'm using OnlyOffice and a coding agent that modifies the files with Python libraries in a sandbox (e.g. python-pptx for PowerPoint files).
Have you also considered using a solution like OnlyOffice for your product? Or a "Notion-like" lib such as Tiptap or PlateJS?
