Upload Contacts to Sharepoint Online

On the top of my head, you could use Microsoft Access or PowerShell PnP to do this, but using Access is probably the most user-friendly way to do it.

1) Convert your CSV file to an Access database
           * Open Access
           * New (blank) database
           * New Data Source (in the ribbon)
           * Choose From File >> Text File
           * Browse to your CSV file
           * Select your preferences for the rest...

2) Modify the records in the Access database (i.e.: Remove columns you don't want)

3) Export to SharePoint List

The columns will be created/added for you in the SharePoint List
PS: You may need to remove the "Title" column from the Access database to avoid conflicts

Works fine 

Cheers
