    "Id":  3944, 
    "Path":  "C:\\Windows\\System32\\WindowsPowerShell\\v1.0\\powershell_ise.exe" 
}

        two = @{    # 2nd iteration 
            three = @{ 
                four = 'value' 
            } 
        } 
    } 
} | ConvertTo-Json 

The three property is present, but the value is listed as System.Collections.Hashtable, as acquiring the value would need a third iteration. Setting the value of the Depth parameter ...
