I have a company table and a contact table. How do I link all contacts to related company automatically? Thank you!

Thank you for your reply. Both the company table and contact table are imported from our own excel spreadsheet. The company name match exactly on the contacts table and the company table. (on our excel spreadsheet, company information and contact info is combined in one spreadsheet). and yes, in the future we will still need to launch both company info and contact info relate to the new companies into Quickbase system.
