| <# | ||
| .SYNOPSIS | ||
| creates a powershell object-notation script that generates the same object data | ||
| .DESCRIPTION | ||
| This produces 'PSON', the powerShell-equivalent of JSON from any object you pass to it. It isn't suitable for the huge objects produced by some of the cmdlets such as Get-Process, but fine for simple objects | ||
| .EXAMPLE | ||
| $array=@() | ||
| $array+=Get-Process wi* | Select-Object Handles,NPM,PM,WS,VM,CPU,Id,ProcessName | ||
| ConvertTo-PSON $array | ||
| .PARAMETER Object | ||
| the object that you want scripted out | ||
| .PARAMETER Depth | ||
| The depth that you want your object scripted to | ||
| .PARAMETER Nesting Level | ||
| internal use only. required for formatting | ||
