Could you build this?
Partial The browser UI and progressive loading are buildable with open-source parsers, but faithful round-trip editing of DOCX, XLSX, and PPTX with formula evaluation and real-time collaboration is a hard engineering problem.
What it would actually take: A real version would use a canvas or virtualized rendering layer, a streaming OOXML parser, and a formula engine (such as HyperFormula) for spreadsheets, with a CRDT or OT sync layer for collaboration. The hard parts are preserving Office format fidelity on save and keeping 300k-row sheets responsive, which requires expertise in document-format internals and performance engineering.
