You underestimate the task by multiple orders of magnitude. It would be a significant effort even to build it on libreoffice.
Within 5 years (maybe less) a frontier LLM will be capable of completely cloning Excel based on Microsoft's product documentation. And I mean starting from scratch, not using the messy Libreoffice code base.
