Synchronizing a customer list with the Sugar CRM database

Hello All,

I try to prepare for a exhibition event.

I have a list of customers (their web address), and I want to check, if one or more of the customers on the list (*.csv file) are listed in my Sugar CRM.

Is there a way to synchronize an external list with the content of  Sugar CRM.

This would be very helpful in a lot of use cases.

Thank you very much!

Thomas
