The article fails to explain in what use case does excel fail. It problem when people make sweeping generalizations blaming a product. Especially one like excel that works.

From what it looks like they're trying to provide "sales reports." It one thing to say that they can simplify and save time generating these reports.

Its any other thing entirely to blame excel. Human error is prevalent on every level, so unless you can completely remove human interaction from the process or do it for them, then you're still open to the same risks.
