Hello, truster.
ETL tools are able to perform the transfer you're describing.
Working for Talend, we have an ETL tool you can use.
Since you describe yourself as a non-technical user, I won't waste your time with technical considerations. Simply put, Talend Open Studio is an open source ETL tool with a user-friendly GUI, easy to learn for a non-technical user.
But what really distinguishes Talend from other tools, when it comes to business users, is the tMap component which allows the user to get a graphical and functional view of integration processes.
Now back to your question, do you only have CSV files or also other files?
