Can PowerShell compare two CSV files? Or should I import the CSV file to multiple worksheets in a single workbook?

Is there a way to import weekly CSV files into an Excel workbook to compare or is there a PowerShell script to compare two CSV files?

Option 1: Within Excel I want my multiple CSV files to be imported into multiple worksheets within a single workbook only and develop a macro to compare two separate sheets with separate weekly AD group membership information and determine if there is a difference. For example, export from AD, with PowerShell, the group membership and determine weekly if there were additions or deletions from the membership list from the prior week.

Option 2: Develop a PowerShell script to compare two CSV files from Week1 & Week2?

Get-ADGroupMember "Domain Admins" | Export-CSV C:\PowerShellOutput\DomainAdminsGroupMembershipWeek1.csv
Get-ADGroupMember "Schema Admins" | Export-CSV C:\PowerShellOutput\SchemaAdminsGroupMembershipWeek1.csv
Get-ADGroupMember "Enterprise Admins" | Export-CSV C:\PowerShellOutput\EnterpriseAdminsGroupMembershipWeek1.csv
Get-ADGroupMember "Administrators" | Export-CSV C:\PowerShellOutput\AdministratorsGroupMembershipWeek1.csv

Get-ADGroupMember "Domain Admins" | Export-CSV C:\PowerShellOutput\DomainAdminsGroupMembershipWeek2.csv
Get-ADGroupMember "Schema Admins" | Export-CSV C:\PowerShellOutput\SchemaAdminsGroupMembershipWeek2.csv
Get-ADGroupMember "Enterprise Admins" | Export-CSV C:\PowerShellOutput\EnterpriseAdminsGroupMembershipWeek2.csv
Get-ADGroupMember "Administrators" | Export-CSV C:\PowerShellOutput\AdministratorsGroupMembershipWeek2.csv

I can give you an option but without Powershell. what about using Excel Add-Ins and VBA? instead of Powershell?
