You can run most Microsoft Office apps free using the official "Online" versions. So no cost, no fees etc, although you need an account (eg Skype, Onedrive etc). Google Docs are very similar, if you have a particular dislike of Microsoft.
Many people are either too paranoid or self important to countenance working online but if you don't want to spend money or pay for a subscription or work online, you have to decide if you actually want to do anything in the first place.
The online versions don't have 100% of the functionality of the full Monty but few of us ever get near that level.
