There is a free web version of Word that is pretty good.
From my experience Word from Office360 breaks complex formatting of desktop Word document even worse, than LibreOffice/Google Docs does.
Closest thing that I use is Google docs, sometimes.... The reason I use vim for everything now is - I use vim for everything.
I’m talking about the Microsoft product that is now sold under the Microsoft 365 Online brand.
It isn’t a perfect replacement but for the times I’ve used it, it’s been pretty good.
