Re: Failure to import CSV with ConvertFrom-Csv

at first we should handle the error "op_addition"

op_addition is a method used by array vars.

you declare

$data = 0

and after you did

$data+=$VM.UsedSpaceGB

So Powershell, return an error! He only does what you ask him to do

SO the import-csv problem, working with a csv file should be done always by import-csv, convertfrom-csv is to use a variable array as a csv. like a http get or so..

i correct your script in this way.

$csvreport = @()

$i=0

$VMNum=0

$data=0

$VMs=Get-VM

$VMCount=$VMs.count

$ofile="C:\Temp\DataGrowth.csv"

 

 

 

 

# Check for file / Read old file if exists

if (Test-Path $ofile){

    $csvreport = Import-Csv $ofile -UseCulture

}

 

 

 

 

foreach($VM in $VMs) {

    #Get-Vm | Foreach-object {

    $entity = $VM

    $VMNum++

 

 

    #Progress Bar

    $Activity="Collecting Stats for VM"

    Write-Progress -Activity "Collecting stats for VM $($entity.Name)"  -Status "VM $VMNum of $VMCount" -PercentComplete (($i/$VMCount)*100)

    $data = $data + $VM.UsedSpaceGB

    $i++

}

 

 

 

 

# Creates List of Custer Details

$clusterdetails = "" |select-object Collection_Date,Total_Size,VM_Count

 

$clusterdetails.Collection_Date=Get-Date -format d

$clusterdetails.Total_Size=[math]::round(($data), 5)

$clusterdetails.VM_Count=$VMCount

 

 

$csvreport += $clusterdetails

 

 

 

 

 

 

$csvreport | export-csv -NoTypeinformation $ofile -UseCulture

Remove-Variable $csvreport
