Import Format for Protected Content Plugin

Am building a membership site using Protected Content.

We have about 163 members that we'd like to manually import from an off-site, third party system.

Can you provide a sample CSV or XLS file that I can use a model for preparing our user data for import?

Also, is it possible to enter a column of data that would populate the EXPIRE DATE for these imported users? If not, then I suppose that I'll just edit this in the database.

However, I have to say, that since the each user data is now in the user_meta table spread across many rows -- instead of in a separate table with each user's data on a single unique row -- it will make a much more difficult job of finding each EXPIRE DATE, and making sure it's the right one for the user that I'm trying to edit.

Is there a better way to do this?

Thank you so much for your answers.
