export reminders to spreadheet to avoid duplicates

As i keep adding reminders, sometimes I want to check whether the birthday wish or anniversary wish is already scheduled. I use SkedIt in my android phone and presently, unable to sort the reminders on recipient name basis or schedled date basis. 

1. Is it possible to export all reminders, also for backup purposes, so that they can be reviewed in a spreadsheet.

2. Also, is it possible to import such reminders from a .csv file, instead of creating them one by one?

3. Possible to backup all SkedIt reminders and restore them in case of phone corruption and factory reset? Do the reminders get saved in some server and get reinstalled automatically by reinstalling the app?
