The object can be stored in a variable, file or any other common storage for later use or to be ported to another system. An expression can be restored to an object using the native Invoke-Expression cmdlet: $Object = Invoke-Expression ($Object | ConverTo-Expression) Or Converting it to a [scriptblock] and invoking it with cmdlets along with `Invoke-Command` or using the call operator (`&`): $Object = &([scriptblock]::Create($Object | ConverTo-Expression)) An expression that is stored in a PowerShell (.ps1) file might also be directly invoked by the PowerShell dot-sourcing technique, e.g.: $Object | ConvertTo-Expression | Out-File .\Expression.ps1 $Object = . .\Expression.ps1 Warning: Invoking partly trusted input with Invoke-Expression or [scriptblock]::Create() methods could be abused by malicious code injections. .INPUTS Any. Each objects provided through the pipeline will converted to an expression. To concatinate all piped objects in a single expression, use the unary comma operator, e.g.: ,$Object | ConvertTo-Expression .OUTPUTS String[]. ConvertTo-Expression returns a PowerShell expression for each input object. .PARAMETER InputObject Specifies the objects to convert to a PowerShell expression. Enter a variable that contains the objects, or type a command or expression that gets the objects. You can also pipe one or more objects to ConvertTo-Expression. .PARAMETER Depth Specifies how many levels of contained objects are included in the PowerShell representation. The default value is 9. .PARAMETER Expand Specifies till what level the contained objects are expanded over separate lines and indented according to the -Indentation and -IndentChar parameters. The default value is equal to the -Depth value. A negative value will remove redundant spaces and compress the PowerShell expression to a single line (except for multi-line strings). Xml documents and multi-line strings are embedded in a "here string" and aligned to the left. .PARAMETER Indentation Specifies how many IndentChars to write for each level in the hierarchy. .PARAMETER IndentChar Specifies which character to use for indenting. .PARAMETER Strong By default, the ConvertTo-Expression cmdlet will return a weakly typed expression which is best for transfing objects between differend PowerShell systems. The -Strong parameter will strickly define value types and objects in a way that they can still be read by same PowerShell system and PowerShell system with the same configuration (installed modules etc.). .PARAMETER Explore In explore mode, all type prefixes are omitted in the output expression (objects will cast to to hash tables). In case the -Strong parameter is also supplied, all orginal (.Net) type names are shown. The -Explore switch is usefull for exploring object hyrachies and data type, not for saving and transfering objects. .EXAMPLE PS C:\> (Get-UICulture).Calendar | ConvertTo-Expression [pscustomobject]@{ 'AlgorithmType' = 1 'CalendarType' = 1 'Eras' = ,1 'IsReadOnly' = $false 'MaxSupportedDateTime' = [datetime]'9999-12-31T23:59:59.9999999' 'MinSupportedDateTime' = [datetime]'0001-01-01T00:00:00.0000000' 'TwoDigitYearMax' = 2029 } PS C:\> (Get-UICulture).Calendar | ConvertTo-Expression -Strong [pscustomobject]@{ 'AlgorithmType' = [System.Globalization.CalendarAlgorithmType]'SolarCalendar' 'CalendarType' = [System.Globalization.GregorianCalendarTypes]'Localized' 'Eras' = [array][int]1 'IsReadOnly' = [bool]$false 'MaxSupportedDateTime' = [datetime]'9999-12-31T23:59:59.9999999' 'MinSupportedDateTime' = [datetime]'0001-01-01T00:00:00.0000000' 'TwoDigitYearMax' = [int]2029 } .EXAMPLE PS C:\>Get-Date | Select-Object -Property * | ConvertTo-Expression | Out-File .\Now.ps1 PS C:\>$Now = .\Now.ps1 # $Now = Get-Content .\Now.Ps1 -Raw | Invoke-Expression PS C:\>$Now Date : 1963-10-07 12:00:00 AM DateTime : Monday, October 7, 1963 10:47:00 PM Day : 7 DayOfWeek : Monday DayOfYear : 280 DisplayHint : DateTime Hour : 22 Kind : Local Millisecond : 0 Minute : 22 Month : 1 Second : 0 Ticks : 619388596200000000 TimeOfDay : 22:47:00 Year : 1963 .EXAMPLE PS C:\>@{Account="User01";Domain="Domain01";Admin="True"} | ConvertTo-Expression -Expand -1 # Compress the PowerShell output @{'Admin'='True';'Account'='User01';'Domain'='Domain01'} .EXAMPLE PS C:\>WinInitProcess = Get-Process WinInit | ConvertTo-Expression # Convert the WinInit Process to a PowerShell expression .EXAMPLE PS C:\>Get-Host | ConvertTo-Expression -Depth 4 # Reveal complex object hierarchies .LINK https://www.powershellgallery.com/packages/ConvertFrom-Expression #> [CmdletBinding()] [OutputType([scriptblock])] param ( [Parameter(ValueFromPipeLine = $true)] [Alias('InputObject')] [object]$Object, [Parameter()] [int]$Depth = 9, [Parameter()] [int]$Expand = $Depth, [Parameter()] [int]$Indentation = 1, [Parameter()] [string]$IndentChar = "`t", [Parameter()] [switch]$Strong, [Parameter()] [switch]$Explore, [Parameter()] [string]$NewLine = [System.Environment]::NewLine ) begin { $listItem = $null $Tab = $IndentChar * $Indentation function Serialize { param ( [Parameter()] [object]$Object, [Parameter()] $Iteration, [Parameter()] $Indent ) function Quote { param ( [Parameter()] [string]$Item ) "'$($Item.Replace('''', ''''''))'" } function Here { param ( [Parameter()] [string]$Item ) if ($Item -match '[\r\n]') { "@'$NewLine$Item$NewLine'@$NewLine" } else { Quote -Item $Item } } function Stringify { param ( [Parameter()] [object]$Object, [Parameter()] [string]$Cast = $Type, [Parameter()] [string]$Convert ) $casted = $PSBoundParameters.ContainsKey('Cast') function Prefix { param ( [Parameter()] [object]$Object, [Parameter()] [switch]$Parenthesis ) if ($Convert) { if ($listItem) { $Object = "($Convert $Object)" } else { $Object = "$Convert $Object" } } if ($Parenthesis) { $Object = "($Object)" } if ($Explore) { if ($Strong) { "[$Type]$Object" } else { $Object } } elseif ($Strong -or $casted) { if ($Cast) { "[$Cast]$Object" } } else { $Object } } function Iterate { param ( [Parameter()] [object]$Object, [Parameter()] [switch]$Strong = $Strong, [Parameter()] [switch]$listItem, [Parameter()] [switch]$Level ) if ($Iteration -lt $Depth) { Serialize -Object $Object -Iteration ($Iteration + 1) -Indent ($Indent + 1 - [int][Bool]$Level) } else { "'...'" } } if ($Object -is [string]) { Prefix -Object $Object } else { $List = $null $Properties = $null $Methods = $Object.PSObject.Methods.Name if ($Methods -contains 'GetEnumerator') { if ($Methods -contains 'get_Keys' -and $Methods -contains 'get_Values') { $List = [Ordered]@{ } foreach ($Key in $Object.get_Keys()) { $List[(Quote $Key)] = Iterate $Object[$Key] } } else { $Level = @($Object).Count -eq 1 -or ($null -eq $Indent -and -not $Explore -and -not $Strong) $StrongItem = $Strong -and $Type.Name -eq 'Object[]' $List = @(foreach ($Item in $Object) { Iterate $Item -ListItem -Level:$Level -Strong:$StrongItem }) } } else { $Properties = $Object.PSObject.Properties | Where-Object { $_.MemberType -eq 'Property' } if (-not $Properties) { $Properties = $Object.PSObject.Properties | Where-Object { $_.MemberType -eq 'NoteProperty' } } if ($Properties) { $List = [Ordered]@{ };
