Filter CSV file with powershell - powershell

Question

I am new to powershell ... I am trying to filter one of my scan result (.csv) on specific value, I am able to do this for simple CSV files. however the automated scan result seems like nested.
I need to filter Column "F" where the value is "Vuln" (Image is added) and write to a new CSV file.
can anyone please give me some leads.
I tried simple lines like : (but I didnt get any result)
Import-CSV -Path "C:\test.csv" | Where-Object {$_.Type -ey"Vuln"}
Sample CSV file format

Answer 1

You're mostly there, it looks like problem is coming from that .CSV file.
Frankly, it isn't a truly valid csv file, since it isn't just a simple Comma Separated Value sheet, instead it has multiple types of data.
However, it looks like something close to a real .CSV begins on line 6, so what we'll need to do is skip the first few rows of the file and then try to convert from .csv. I made my own .csv like yours
I can read the file and skip the first five lines like so:
Get-Content C:\temp\input.csv | Select-Object -Skip 5 | ConvertFrom-Csv
HostName OS Type
-------- -- ----
SomePC123 WinXp Vuln
SomePC234 Win7 Vuln
SomePc345 Win10 Patched
And then filter down to just items of Type Vuln with this command:
Get-Content C:\temp\input.csv | Select-Object -Skip 5 | ConvertFrom-Csv | Where-Object Type -eq 'Vuln'
HostName OS Type
-------- -- ----
SomePC123 WinXp Vuln
SomePC234 Win7 Vuln
To use this, just count down the number of lines until the spreadsheet begins within your .CSV and edit the -Skip parameter to match.
If you want to keep the header information, you can use an approach like this one:
$crap = Get-Content C:\temp\input.csv | Select-Object -First 5
$OnlyVulns = Get-Content C:\temp\input.csv | Select-Object -Skip 5 | ConvertFrom-Csv | Where-Object Type -eq 'Vuln'
$CrapAndOnlyVulns = $crap + $OnlyVulns
$CrapAndOnlyVulns > C:\pathTo\NewFile.csv

Here is the final script :)
$import = get-content .\Scan.csv
$import1= $import | Select-Object -First 7
$import | Select-Object -Skip 7 | ConvertFrom-Csv | Where-Object {$_.Type -eq "Vuln"} | Export-Csv Output1.csv -NoClobber -NoTypeInformation
$import1 + (Get-Content Output1.csv) | Set-Content Output2.csv
