The customer wants the brand new website we are building them to be able to load data from several types of excel files and then email them an excel file with results. Please shoot me...
Customer wants a database, but has the MBA learning disability? Yes, literally the primary use of excel. Microsoft would go bankrupt without MBA brain rot.
It can be sometimes. I do a simple import in one of my personal projects. In case for the client, for over 20 years they have used excel to make all CRUD changes and now they get to build a brand spanking new website to do all of those CRUD changes and they still want to do it in excel.
