Excel is a bad database?
I think OP was overly trying to be critical of popular things.
Wix is a website with database features, having a back end has purpose.
Using Excel as a traditional database is not what Excel does. Excel is often good enough at storing data that people use it like a database.
Anyway this seemed like a Pop Programming article. Lots of Python and coding love, bashing WYSIWYG and Microsoft products.
