XLSX is actually a decent format for business users. The only trouble is it has tons of limits [1], most restrictive being the limit of 1,048,576 rows by 16,384 columns. I'm working with a client who had to split up their data into several XLSX files because they hit a row limit. They can of course ETL the data into a real SQL database, but ETL tools for end users are still not a common thing plus not all end users have access to a SQL database.
