Create multiple subdomains for multi-site from a database

Question

I want to create multiple subdomains for users.
I know how to create multiple subdomains manually using creating network.

But, i have so many users, I can't create those subdomains manually one by one.

I have a user list in an Excel file:

id || username || password || subdomain

 1 || alex     || ****     || alex.websitewordpress.com

 2 || brad     || ****     || brad.websitewordpress.com

 3 || carol    || ****     || carol.websitewordpress.com

 4 || donald   || ****     || donald .websitewordpress.com

How can I create multiple subdomains automatically using the data from my Excel file?

Answer 1

More than an answer, a study on the matter.

The Excel issue

• we need an array, and Excel can provide a CSV
• a couple of solutions: How to extract data from csv file in php? _{not implemented here}

Testing code

• Based on OneTrickPony first Question.
• Must run only once. I don't know of a better method.
• I'm not sure if admin_init is the best place to run this.
• Haven't measured, but this code does not runs fast (3 sites in this sample).
• There's an awful CSS bug in the admin after running the code. After disabling the hook and reloading the page everything is ok and all sites had been created.

/* Enable the hook, refresh the dashboard, <WAIT>, disable again */
// add_action('admin_init','wpse_54647_testing_code');

{
    $site = get_current_site();
    
    $meta = array( 
            'blogdescription'       => 'blog description'
        ,   'users_can_register'    => 1 
    );
    
    $sites_array = array(
        
            array(
                    'title'   => 'site 1'
