Hello ... ( I do not know your name)

I want to make a convertion with database from clients in Excel format to 

Server in Oracle format in order to make a contact between School and Home.

Excel sheets are mark(score) boards of pupils. I am running Intranet with 

NT Server 4.0 (Option Pack 4) and Oracle 8i.

Can you tell me how to do a automatic convertion. Support me Ocx related.

Thank you Advanced. Your faithfully!
