Need help on a power shell script to filter the CSV on Columns and display the filtered data in new sheet - powershell

Question

I am new to power shell but learning it fast. So far i have made a script which is fetching the data from URL and creating a csv on the desktop and then i remove the first row from the CSV and saving it to desktop as csv2. I want to filter the column and copy the filtered data in new sheet. I may have to declare the array values to be looked for filtering and i need help on that. So far i have made the below script:-
\This script is made to download the asset analysis servers list with their corresponding site address and country and will save the output to CSV on C:\Users\vtarwani\Desktop.
Invoke-WebRequest -Uri "Link to URL" -OutFile "C:\Users\tarwaniv\Desktop\file1.csv"
$import = get-content "C:\Users\tarwaniv\Desktop\file1.csv"
$import | select-Object -Skip 1 | Set-Content "C:\Users\tarwaniv\Desktop\file2.csv"
Import-csv -Path "C:\Users\tarwaniv\Desktop\file2.csv" -Header "#Active Servers", "Street Address" , "City", "Country" | Where-Object {$_.Country -eq "UNITED STATES"}

I agree with #Theo and #Olaf. This is difficult to follow. Hopefully you'll be able to build off an example like this:
$WebFile = "C:\Users\tarwaniv\Desktop\file1.csv"
$Out_Dir = "C:\Users\tarwaniv\Desktop\"
$Headers = "#Active Servers", "Street Address" , "City", "Country"
Invoke-WebRequest -Uri "Link to URL" -OutFile $WebFile
Import-csv -Path $WebFile -Header |
Select-Object -Skip 1 |
Group-Object -Property Country |
ForEach-Object{
$OutFile = $Out_Dir + $_.Name
$_.Group | Export-Csv -Path $OutFile -NoTypeInformation
}
Note: using -Skip parameter on Select object should skip the first record coming from Import-Csv.
Use Group-Object to group on the Country. That will output its own objects, but the name property is what you grouped on, in this case Country, and the Group property has the original objects in it. So we can use these 2 properties to name an output file then export the objects to the new Csv file.
If you want to only output a subset of the columns coming from the initial file. add the -Property parameter to the Select-Object command like:
Select-Object -Skip 1 -Property <PropertiesToSelect>
Note: You can declare an array of properties similar to $Headers above.
If you want top filter on additional columns, and assuming they were included in the Select-Object command just build on the Where-Object clause.
Please bear in mind I couldn't really test this, so consider it a starting point. That said let me know how it turns out. Thanks.
