Powershell - Export to multiple sheets in an Excelfile

Hello,

Ik hope somebody can help me. Ik have a Powershell script and i use this to export a couple OU's in the Active Directory.
This exports go each to there own CSV file (as backup). I realy would like the exports go to one Excel file, each in different sheets.

So for example if i have 3 OU's: Employees, OU: Functional Mailboxes and OU: Disabled Accounts.

I want the OU's have there own sheet in an .XLSX-file so i can easely make an report of the accounts.

Below is the script that i use to export one OU and make an CSV file as backup and export to XLSX.

I miss the import part for multiple CSV's:

clear-host

import-module ActiveDirectory

$Employees="OU=Employees,OU=Accounts,OU=LocationA,DC=DOMAIN,DC=COM"

$workbook = $excel.workbooks.add()
$sheet = $workbook.workbooks.Item(1)
$sheet.cells.item(1,1) = "Test"

$Users = Get-ADUser -Filter * -SearchBase $Employees -Properties * | Select-Object -Property Name,Description | 
Sort-Object -Property Name | Where-Object {$_.Name -like "*" -and $_.Enabled -ne $TRUE }| 
Export-Csv -Delimiter “,” -Path "C:\export_users.csv” -NoTypeInformation

$excel = new-object -comobject excel.application
$excel.visible = $true
$workbook = $excel.workbooks.add(“C:\export_users.csv”)
$workbook.workSheets.Item(3).delete()
$workbook.workSheets.Item(2).delete()
$workbook.WorkSheets.Item(1).Name = "Users"
$sheet = $workbook.WorkSheets.Item("Users")
$x = 2
$sheet.cells.item(1,1) = "Name"
$sheet.cells.item(1,2) = "Description"

foreach($ADUser in $Users)
{
 $sheet.cells.item($x, 1) = $Users.name
 $sheet.cells.item($x,2) = $Users.workingSetSize
 $x++
} 

$range = $sheet.usedRange
$range.EntireColumn.AutoFit() | out-null

$table=$workbook.ActiveSheet.ListObjects.add( 1,$workbook.ActiveSheet.UsedRange,0,1)
$workbook.ActiveSheet.UsedRange.EntireColumn.AutoFit()
$excel.DisplayAlerts=$False
$workbook.SaveAs("C:\Export.xlsx",51)

On this pont the sheets 2 and 3 will be deleted but i would realy like the sheets filt with de other OU's

Ik hope someone can help me with this.

Sorry for crappy English.

Greets,

Hendrik.
