Best way to import users and send them passwords

[santinuro]

Hi,

I´ve installed a prestashop and I need import more than 1000 users, to be honest I don´t know what is the best way to do that.

 

The users I already have, they come from Wordpress. I don´t have too much information about them; mail, name, surname, and password.

 

I don´t care if I can import the password. I need to import all users, and after send them the new password for each one.

 

How do I must proceed?

 

Thanks a lot!
