Journal or notes app recommendation

[jeyf]

recommendation please:
need a note / journal app strong to import a large CSV file from my previous note product that i have been using for years.
One text entry per day.
I am really into being able to import and export the whole data base.

other would be nice:
sync over drop box, able to manage existence on several computers and or iphone.
