I have been trying to import a spreadsheet into google calendar,i have saved the file as a CSV with delimited comma as Google states.
When calendar tries to import it a message come up the fail to import.

The original XLS file has some formula in the fields. The file is a year planner my work shifts. I have recently had a heart op and this would be handy to call up when i am working out the various doctors appointment that i have to keep.
