It seems from quick experimentation that when importing from CSV the expected date format is “YYYY-MM-DD” and the expected number format is “#.###,00”.
Is there a way to set the locale so that here in the USA I can import data using “MM-DD-YYYY” and “#,###.00”?
I did not check if it actualy works but when you double click on column in the importer you can choose different formats. I believe thats what you are looking for? It seems your format for the Date is not there, but for numbers the different decimal points exist. YYYYMMDD is probably the closest to the american format.
