If you're thinking regular office workers, they know of no alternative.
Excel works enough for small data, particularly when you don't do complex queries on it. The more you know of it, the better it works. The only other thing that offers similar benefits to Excel but works as a database is MS Access, but the mental model behind it is too complex for your average office worker who wasn't trained in it, and like most database systems, requires a lot of up-front work with figuring out the schema, and doesn't particularly like the schema being modified later on.
As far as I can tell, there's literally nothing else out there. No, random SaaS webapps du jour don't count, because they're universally slow, and also store the data in the cloud, instead of the local drive.
