Hello soussou97,
My approach is to save the values of your first and second column (the columns you want to sort your values with) in ArrayLists and then use dynamic variables to save the actual content. Look at the following code. It should be able to display the information
you need. 
#Specify the path of the excel file
$FilePath = 'Path\file.xlsx'
#Specify the Sheet name
$SheetName = "Sheet"
# Create an Object Excel.Application using Com interface
$objExcel = New-Object -ComObject Excel.Application
# Disable the 'visible' property so the document won't open in excel
$objExcel.Visible = $false
# Open the Excel file and save it in $WorkBook
$WorkBook = $objExcel.Workbooks.Open($FilePath)
# Load the WorkSheet 'BuildSpecs'
$WorkSheet = $objExcel.sheets.item($SheetName)
# I am taking row count as 2, because the first row in my case is header
$intRow = 2
[System.Collections.ArrayList]$farr = @()
[System.Collections.ArrayList]$sarr = @()
Do {
# Reading the first column of the current row
$First = $WorkSheet.Cells.Item($intRow, 1).Value()
# Reading the second column of the current row
$Second = $WorkSheet.Cells.Item($intRow, 2).Value()
# Reading the third column of the current row
$Third = $WorkSheet.Cells.Item($intRow, 3).Value()
"First: " + $First
"Second: " + $Second
"Third :" + $Third
if($farr -notcontains $First){
$farr.Add($First)
if($sarr -notcontains $Second){
$sarr.Add($Second)
$variable = Get-Variable -Name "$First-$Second" -Scope Global -ErrorAction SilentlyContinue
if ($variable -eq $null)
Write-Host "$First-$Second does not exist"
New-Variable -Name "$First-$Second" -Value $Third
else{
$val = Get-Variable -Name "$First-$Second" -ValueOnly
Set-Variable -Name "$First-$Second" -Value $val","$Third
$intRow++
}While ($WorkSheet.Cells.Item($intRow,1).Value() -ne $null)
foreach($dec in $farr){
foreach($city in $sarr){
$variable = Get-Variable -Name "$dec-$city" -Scope Global -ErrorAction SilentlyContinue
if ($variable -ne $null){
$dec+"--"+$city+"--"+$variable.Value;
my sample data looks like this
col1 | col2 | col3
abc | qwe | poi
abc | jhg | dfg
de | wer | rew
de | iuz | mnb
abc | qwe | iop
de | wer | asd
