Maybe within the strict confines of these cases made by Microsoft, which also have inherent monopoly designs behind them.
Office documents are still fundamentally opaque to data extraction and generation. The user interfaces of the components are still heavily restricted to dedicated applications as opposed to providing some sort of means of embedding them in other contexts such as gasp a web page that might have an actually good Excel interface.
And I would say in general llm should be a massive boon to closing the compatibility gap between free office applications and the barriers put up by proprietary ones, particularly format. Parsing and saving
If we can have an office document foundation similar to what Labor office does to provide generalized libraries and code for parsing office document formats saving them across many platforms, something that just piecemeal across most programming languages and environments, it could be a huge boon to open days formats represented by these relatively important file formats:
The spreadsheet
The word document
The presentation
The flowchart/chart
Well, Microsoft with things like OLE kind of pushed some of these capabilities across the Microsoft ecosystem. That sucks and it failed because it was within the Monopoly.
But the vision was a good one.
