Create Profile info for not logged users

[SR]

Suppose I have to create a dozen of users taking their data from a list

Membership let me do it with the Create method, but what about Profile ?
eg. I want FullName, Age (in Profile) UserId, pwd (in membership)

something like (pseudocode):
for each user in excel file
Membership.CreateUser("john","....")
// this doesn't work...
ProfileCommon p = new ProfileCommon();
p.GetProfile("john")
p.Fullname = ..
p.Age = ...
p.Save()


Thanks
