Importing old DB how can I make it looking good?

Hi, I’m using this plugin which is great. I’ve tried to import 2 people from the example.csv just to test it, and it works like a charm.

Now I have a question. I need to import a csv from an old database which contains about 1000 customers. But I know that the csv from the example is made from a certain way, the columns have particular names sunrouded by ” ” and there is a certain number of column.

So the question is how can I make my old DB working and become like the one in the example?

I have the same information of my customers, first name, last name, password, email, role (admin or reader) and that’s almost all.

Thanks for your help :/

Sincerely,
