How to loop through VMs without a specific tag with powercli

Question

I'm trying to export a CSV file that has a list of all VM's in a cluster that doesn't have a specific tag I'm using for rightsizing. However, the list CSV isn't populating with anything other than this: ÿþ

Get-Module -Name VMware* -ListAvailable | Import-Module -Force
$exportto = "C:\Users\username\Desktop\rightSizingFilter3.csv"
$VMs = Get-Cluster -name clustername | Get-VM
 
foreach ($VM in $VMs){
    If (((Get-Tagassignment $VM).Tag.Name -notcontains "testtag")){
         Out-file $exportto -Append
    }
}

Answer 1

Answer from another section:

Get-Module -Name VMware* -ListAvailable | Import-Module -Force
Connect-ViServer -Server [SERVERNAME] -Credential (Get-Credential)
$ExportTo = ".\rightSizingFilter3.csv"
$VMs = Get-Cluster -Name [CLUSTERNAME] | Get-VM
 
foreach ($VM in $VMs) {
    If ( ((Get-Tagassignment $VM).Tag.Name -notcontains "testtag") ) {

         Export-Csv -InputObject $VM -Path $ExportTo -Append -NoTypeInformation
    }
}

Answer 2

I got it to work from the snippet below:

$RS = foreach ($VM in $VMs){
    If (((Get-Tagassignment $VM).Tag.Name -notcontains "testtag")){
        Write-Output $VM
    }
}
$RS | Out-file $exportto -Append
