Customer wants to download all Activities (Events) at the end of each month, modify some dates, and then upload them. They would like to do this pragmatically and they are currently on PE, NOT EE. If they get the API add on, would they be able to do this with their current PE using the EE version of Excel Connector?

If not, what would be your recommendation for them? They are trying to avoid the expense of upgrading to EE.

Thanks.
