Import (New or) Set Distribution Groups with CSV Powershell

I need to create new distribution groups into Active Directory with these attributes (as the headers):

DisplayName      Alias      LegacyExchangeDN      PrimarySmtpAddress      ManagedBy      EmailAddresses      EmailAddresses02      EmailAddresses03      EmailAddresses04

How would we utilize a CSV of this nature to create/populate all the Distribution Groups?
Thank you!

Thank you for your reply. However, I have seen this page before and I don't see any that reference a CSV.

Of yourse you have to add add'l parameters for the other fields you need.

Can't check right now if you can provide all required fields with New-DistributionGroup. It might be necessary to do an extra loop for example to set the owner or add add'l mail addresses.

All the required fields are in the original question. Again, thank you for your reply.

As I told you I can't check this now so this is just theory

Import-CSV C:\Temp\DL-Group.csv | ForEach {New-DistributionGroup -Name $_.DisplayName -DisplayName $_.DisplayName  -Alias $_.Alias  -PrimarySmtpAddress $_.PrimarySmtpAddress -ManagedBy $_.ManagedBy -Type "Distribution"}

Import-CSV C:\Temp\DL-Group.csv | ForEach {$AddressList = "SMTP:"+$_.EmailAddresses + "," + $_.EmailAddresses02+ "," + $_.EmailAddresses03 + "," + $_.EmailAddresses04
	Set-DistributionGroup $_.DisplayName -EmailAddresses $AddressList 
	Set-ADGroup -Identity $_.DisplayName -add @{proxyAddresses=”X500:$($_.LegacyExchangeDN)}
}
