Mentioning libreoffice as competitor to Excel and Access is like you haven't understood the market, at all.

Excel is a cross department business automation database, which can sync/pull/push datasets across filesystems and networks.

VBA is the single most used language in Enterprise because it allows to automate pretty much any financial workflow. And more importantly: automated by non-programmers.

Libreoffice is made for private users, and that's not the same users that VBA powered office documents have.
