HI Andreas that worked as well. The formats are all in tact :)
This means that everything is fine with Excel.
Dighi's tip just aims to do the same thing, opening the export with Notepad. This has no relevance for the exported data, this is also a rumor that has been coming up again and again for decades.
Aeons ago it was decided to associate the CSV file type with Excel and when opening a CSV, Excel has to interpret the content and show it due to your Region settings of your OS, hence the different date format.
This article shows how to import CSV into Excel correctly, but it has nothing to do with your problem.

If you still have difficulties reading the CSV into your database, then the problem is not with the CSV file, but with the interface of your database.
Andreas.
