Hi @Jhon ,

To delete users in bulk, you can follow below steps:

• Navigate to Azure AD B2C > Users > All Users > Bulk Operations > Download Users. This will download a list of all users in the B2C tenant with their original UPN, Display name, Mail, AlternateEmailAddress and so on in a CSV file.
• Navigate to Azure AD B2C > Users > All Users > Bulk Operations > Bulk Delete and download CSV file.
• From the file downloaded in step 1, copy the UPNs of the users that you want to delete and paste in the file downloaded in step 2, as shown below:
  
• Navigate to Azure AD B2C > Users > All Users > Bulk Operations > Bulk Delete and upload the updated file.
• Type 'Yes' to continue and click on submit.

Note: This will soft delete all the users listed in the uploaded file. Which means the users will be moved to Deleted users and then gets hard/permanently deleted automatically after 30 days. If you want to permanently delete the users before 30 days, you'll have to manually delete the users from the Deleted users blade.

Hi @Jhon Please find below the script for this purpose:

Connect-MsolService #sign-in using Global Admin of your B2C tenant. User should be Member of the tenant and not signed-up or guest user.  
$users = import-csv C:\temp\users.csv  
foreach ($usr in $users)  
{  
Remove-MsolUser -UserPrincipalName $usr.upn -Force  
}  

Below is how the user.csv file looks:
