> you should be able to tell it whether a certain column is a date or not,

Not only is this possible, but the tool to do it is located in best location (large menu, center of the screen on the first ribbon tab). It take literally 2 clicks to do it once your cells or columns are selected. The only problem with this tool is that you have to use before copying your data and it can be frustrating if you forget to do it. If you want to import a file instead of copy-pasting the data, it's only like 1 or 2 extra clicks to set the data type for a column during the import.

And btw, the CSV format was intentionally designed to NOT have type information imbedded in the file itself. The application that is reading the CSV file must know the datatype for each column. For a versatile tool like excel, they is no perfect way to implement it and there will always be a fraction of users of have to override the choices made by by the software. For advanced users who use it everyday, you learn very quickly if the type of data you are normally working with will require you to force it or if excel will understand it correctly.

It looks to me like almost all of the anti-Excel comments on HN (including yours) are made by people who never or extremely rarely uses it and don't know what it can or can't do. It's typical that most if not all of the "missing features" listed by people on NH have been part of excel for at least a decades.
