Create port groups from excel

I've got a spreadsheet with 60 port groups I need to create. My fields are VLAN and Name. Looking at the cmdlets reference guide it looks like the command to create one would be Get-VDSwitch -Name “Boston” | New-VDPortgroup -Name “Test SQL VLAN 250″  -VLanId 250 . Can someone help with the structure to create this from an excel file? I am checking the config maximums to see if I am going to hit a limit on my ports with vSphere 5.1 and need to set a certian number of ports per port group. Thanks.
