<# .SYNOPSIS Convert an object into a HashTable .DESCRIPTION Convert an object into a HashTable, can be used with json objects to create a HashTable .PARAMETER InputObject The object you want to convert .EXAMPLE PS C:\> $jsonString = '{"Test1": "Test1","Test2": "Test2"}' PS C:\> $jsonString | ConvertFrom-Json | ConvertTo-Hashtable .NOTES Author: Mötz Jensen (@Splaxi) Original Author: Adam Bertram (@techsnips_io) Original blog post with the function explained: https://4sysops.com/archives/convert-json-to-a-powershell-hash-table/ #> function ConvertTo-Hashtable { [Diagnostics.CodeAnalysis.SuppressMessageAttribute('PSUseOutputTypeCorrectly', '')] [Diagnostics.CodeAnalysis.SuppressMessageAttribute('PSUseCmdletCorrectly', '')] [CmdletBinding()] param ( [Parameter(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 [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 $collection } elseif ($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 } $hash } else { ## If the object isn't an array, collection, or other object, it's already a hash table ## So just return it. $InputObject } } } |
