How well does change tracking work in Excel... how hard would it be to review LLM changes?
AFAIK there is no 'git for Excel to diff and undo', especially not built-in (aka 'for free' both cost-wise and add-ons/macros not allowed security-wise).
My limited experience has been that it is difficult to keep LLMs from changing random things besides what they're asked to change, which could cause big problems if unattackable in Excel.
I thought there was track changes on all office products. Most Office documents are zip files of XML files and assets, so I'd imagine it would be possible to rollback changes.
