<# .SYNOPSIS Displays an object's nested properties and their values .DESCRIPTION Expands any complex PowerShell object for analysis or comparison. Format-PSObject returns a list of dot walked paths for each of the object's properties, along with values, up to the depth limit. .PARAMETER InputObject The object to format .PARAMETER Depth The recursive limit for nested object property values .PARAMETER IgnoreProperty An array of property names to skip formatting .PARAMETER Parent For internal use, but you can specify the base name of the variable displayed in the path .PARAMETER CurrentDepth For internal use .EXAMPLE Format-PSObject -InputObject @{value1 = 'testvalue'; value2 = @{nestedValue = 'nested'}} Create a property mapping of the 'InputObject' properties and their respective values .NOTES Adapted from https://www.red-gate.com/simple-talk/blogs/display-object-a-powershell-utility-cmdlet/ #> function Format-PSObject { [CmdletBinding()] param ( [Parameter(Mandatory, ValueFromPipeline)] [object]$InputObject, [Parameter()] [int]$Depth = 5, [Parameter()] [string[]]$IgnoreProperty, [Parameter(DontShow)] [string]$Parent = '$_', [Parameter(DontShow)] [int]$CurrentDepth = 0 ) begin { if ($CurrentDepth -eq 0) { $reachedDepthLimit = $false } } process { if ($CurrentDepth -ge $Depth) { # Prevent runaway recursion $Script:reachedDepthLimit = $true } if ($null -eq $InputObject) { return $null } $ObjectTypeName = $InputObject.GetType().Name Write-Verbose "[$Parent] ObjectType = $ObjectTypeName" if ($ObjectTypeName -in 'HashTable', 'OrderedDictionary') { # If you can, force it to be a PSCustomObject in order to enable iterating over the properties $InputObject = [pscustomObject]$InputObject $ObjectTypeName = 'PSCustomObject' } if (-not ($InputObject.Count -gt 1) -and -not ($InputObject -is [System.Collections.IEnumerable])) { if ($ObjectTypeName -in @('PSCustomObject')) { $MemberType = 'NoteProperty' } else { $MemberType = 'Property' } if ($InputObject) { Get-Member -InputObject $InputObject -MemberType $MemberType -Force | Where-Object { $_.Name -notin $IgnoreProperty } | ForEach-Object { $property = $_ try { $child = $InputObject.($property.Name) $psTypeName = try { $Child.GetType() } catch { $null } } catch { # Prevent crashing on write-only objects $child = $null } if ( $child -eq $null -or $child.GetType().BaseType.Name -eq 'ValueType' -or $child.GetType().Name -in @('String', 'String[]') ) { [pscustomobject]@{ 'Path' = "$Parent.$($property.Name)" 'Value' = $Child 'PSTypeName' = $psTypeName 'Depth' = $CurrentDepth } } elseif (($CurrentDepth + 1) -eq $Depth) { $Script:reachedDepthLimit = $true [pscustomobject]@{ 'Path' = "$Parent.$($property.Name)" 'Value' = $Child 'PSTypeName' = $psTypeName 'Depth' = $CurrentDepth } } else { $FormatPSObjectParams = @{ InputObject = $child depth = $Depth IgnoreProperty = $IgnoreProperty Parent = "$Parent.$($property.Name)" CurrentDepth = $currentDepth + 1 } Format-PSObject @FormatPSObjectParams } } } } else { 0..($InputObject.Count - 1) | ForEach-Object { $iterator = $_ $child = $InputObject[$iterator] $psTypeName = try { $Child.GetType() } catch { $null } if ( ($null -eq $child) -or #is the current child a value or a null?
