Hi Henry,
your investigations are absolutely right!
The decimal character replacement that youve successfully configured is a workaround especially for Excel, which should primarily use the data list type 2. The fieldnames you have mentioned are part of list type 1 and they were actually not designed for the excel-export...
(List_1 is exporting a list "Day-by-Day", List_2 is exporting a data list "Record-by-Record")
I will keep in mind if we can put the decimal replacement to the other fields too but we need to check the implications to this code fraction.
As a quick workaround you could try to modify your Diabyte-Template and enhance the Blood_Clucose place holders like that:
[BLOOD_GLUCOSE1$REPLACE(.~,)] or [BLOOD_GLUCOSE1$REPLACE(,~.)]
