Script get information from excel to Vm description

Hello,

i'm interesting to do a particular script with powershell ( if it is possible) who can get a data from my excel file and put it in custom field in vm description.

In particular, i have a lot of vm ( about 800 ) and i have all data of them ( description , service installed etc..)  in a file excel and i would like put them into a custom field created with Vsphere client. Is it possible with Powershell???

I searched on web but i see only export information from vsphere to excel... but not from excel to vcenter/esx.

The version of vsphere is 4.1 .

Thank you
