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

oK.

for merging all CSV files into single workbook, use the below code in VBA module.

for example run it in the attached two workbook of CSV files.

then for comparison purposes, use one of these free Add-Ins http://www.ilovefreesoftware.com/30/featured/4-free-add-ins-to-compare-excel-files.html


i have not tested other, but this one only http://sourceforge.net/projects/spreadshcompare/



Sub mergebooks()
    Dim openfiles
    Dim crntfile As Workbook
    Set crntfile = Application.ActiveWorkbook
    Dim x As Integer
    On Error GoTo ErrHandler
    Application.ScreenUpdating = False
    openfiles = Application.GetOpenFilename _
    (FileFilter:="Microsoft Excel Files (*.csv;*.csv),*.csv;*.csv", _
    MultiSelect:=True, Title:="Select Excel file to merge !")

    If TypeName(openfiles) = "Boolean" Then
        MsgBox "You need to select atleast one file"
        GoTo ExitHandler
    End If

    x = 1
    While x <= UBound(openfiles)
        Workbooks.Open Filename:=openfiles(x)
        Sheets().Move After:=crntfile.Sheets(crntfile.Sheets.Count)
        
        x = x + 1
    Wend
ExitHandler:
    Application.ScreenUpdating = True
    Exit Sub

ErrHandler:
    MsgBox Err.Description
    Resume ExitHandler
End Sub
