How to remove HTML encoding from csv file using powershell

Question

Hi guys i am exporting data from a sharepoint list using powershell which works fine. My problem is that some of the fields contain HTML mark up. Is there a way to remove all of the html mark up from the array before writing it to csv ?
I have tried playing about with System.Web.HttpUtility.HtmlDecode but with no luck the code runs but no html is removed.
Below is a sample of my script.
Set-Variable HOME $env:USERPROFILE -Force
(Get-PSProvider FileSystem).Home = $HOME
if(-not(Get-PSSnapin | where { $_.Name -eq "Microsoft.SharePoint.PowerShell"}))
Add-PSSnapin Microsoft.SharePoint.PowerShell;
# imports assembly needed for url stuff to do
Add-Type -AssemblyName System.Web
$SPWeb = Get-SPWeb "http://site url"
$SPList = $SPWeb.Lists["List Name"]
$exportlist = @()
$SPList.Items | foreach {
$obj = New-Object PSObject -Property @{
"Employee full name" = $_["EMPLOYEEFNAME"]
"Employee login name" = $_["EMPLOYEENAME"]
"Department Name" = $_["DEPARTMENT"]
System.Web.HttpUtility.HtmlDecode("OBJECTIVESTOBEACHIEVED_0") = $_["F1_S4a_OBJECTIVESTOBEACHIEVED_0"]
"OBJECTIVESTOBEACHIEVED_1" = $_["F1_S4a_OBJECTIVESTOBEACHIEVED_1"]
"OBJECTIVESTOBEACHIEVED_2" = $_["F1_S4a_OBJECTIVESTOBEACHIEVED_2"]
"OBJECTIVESTOBEACHIEVED_3" = $_["F1_S4a_OBJECTIVESTOBEACHIEVED_3"]
"OBJECTIVESTOBEACHIEVED_4" = $_["F1_S4a_OBJECTIVESTOBEACHIEVED_4"]
"OBJECTIVESTOBEACHIEVED_5" = $_["F1_S4a_OBJECTIVESTOBEACHIEVED_5"]
"OBJECTIVESTOBEACHIEVED_6" = $_["F1_S4a_OBJECTIVESTOBEACHIEVED_6"]
"OBJECTIVESTOBEACHIEVED_7" = $_["F1_S4a_OBJECTIVESTOBEACHIEVED_7"]
$exportlist += $obj
$exportlist | select "Employee full name", "Employee login name", "Department Name", "OBJECTIVESTOBEACHIEVED_0", "OBJECTIVESTOBEACHIEVED_1", "OBJECTIVESTOBEACHIEVED_2", "OBJECTIVESTOBEACHIEVED_3", "OBJECTIVESTOBEACHIEVED_4", "OBJECTIVESTOBEACHIEVED_5", "OBJECTIVESTOBEACHIEVED_6", "OBJECTIVESTOBEACHIEVED_7" | Export-Csv ~/Export.csv -noType
$SPWeb.Dispose()
any help would be much appreciated.

Should have googled before posting !
"OBJECTIVESTOBEACHIEVED_0" = [Microsoft.SharePoint.Utilities.SPHttpUtility]::ConvertSimpleHtmlToText($_["F1_S4a_OBJECTIVESTOBEACHIEVED_0"],-1) -replace '\s+', ' '
Clears all the additional white space. As always jrv you
