how to create auto populate data into Excel Calendar?

hi 

can anyone help I lost the earlier post, I am trying to create a dynamic calendar that can auto-populate the event info into the calendar to view

Please advise how to 

as some event falls in the same date
can it show using text join for the title, total invitee, start time and end time and venue?   Thank you

Try to find in YouTube but failed to source for one that can create.   

How to attach a file to the post?   Thank you
