Just bought the app. Still need do move many years from EfficientDiary to Diarium. I can export a csv and convert it to any given format with small Python script. However, a good specification for some csv format would be very helpful. Since i have none of the supported diaries, i did trial and error. A bit tedious. So far i found out that the following works quite well for me using Daylio import:
except that it appears in Diarium as a single line. So what would be the newline markup in the Daylio csv?
