Function ConvertTo-Hashtable { <# .SYNOPSIS Converts a PSCustomObject into a hashtable for Windows PowerShell .NOTES Author: Adam Bertram Link: https://4sysops.com/archives/convert-json-to-a-powershell-hash-table #> [OutputType([System.Collections.Hashtable])] [CmdletBinding(SupportsShouldProcess = $False)] param ( [Parameter(Position = 0, ValueFromPipeline)] $InputObject ) process { ## Return null if the input is null. This can happen when calling the function ## recursively and a property is null if ($null -eq $InputObject) { return $null } ## Check if the input is an array or collection. If so, we also need to convert ## those types into hash tables as well. This function will convert all child ## objects into hash tables (if applicable) if ($InputObject -is [System.Collections.IEnumerable] -and $InputObject -isnot [System.String]) { $collection = @( foreach ($object in $InputObject) { ConvertTo-Hashtable -InputObject $object } ) ## Return the array but don't enumerate it because the object may be pretty complex Write-Output -NoEnumerate -InputObject $collection } elseif ($InputObject -is [PSObject]) { ## If the object has properties that need enumeration ## Convert it to its own hash table and return it $hash = @{ } foreach ($property in $InputObject.PSObject.Properties) { $hash[$property.Name] = ConvertTo-Hashtable -InputObject $property.Value } Write-Output -InputObject $hash } else { ## If the object isn't an array, collection, or other object, it's already a hash table ## So just return it.
