IPAM: Importing host names into a subnet

The sample spreadsheet I download is showing Type Subnet, Group and Supernet. I am trying to transition from a spreadsheet 

that was used for IP address assignment to using IPAM. I there a way to import a list of host names and addresses into 

a spreadsheet? Or description and IP address if host name is always derived from DNS?

Address/CIDR Address CIDR Type Subnet Group Supernet
