Convert-JsonToHashtable

#A hashtable converted into a json string can be converted back to hashtable like so:
#Create a hashtable, convert to json
$hash = @{"Name1"="Value";"Name2"="Value2"}
$json = $hash | ConvertTo-Json


#Take the json string and convert it back:
$newobject = $json | ConvertFrom-Json
$newhash = @{}
foreach ($prop in $newobject.psobject.Properties)
{
    Write-verbose "added property $($prop.name) with value $($paramobject.($prop.name))" 
    $newhash.Add($prop.name,$newobject.($prop.name))
}
$newhash
