I'm trying to use Excel Connector to import data into Salesforce. A colleague of successfully used it before and now I want to finish the job. Our Salesforce database already contains all our clients. When I connect with Excel Connector using the server URL
https://www.salesforce.com/services/Soap/c/13.0 the list of accounts seems to be part of a sandbox database.
Is there maybe some user setting in Salesforce for my account that is set wrong?
