I needed to serialize objects and save them to disk. It needed to be very efficient to be able to support a high volume of objects. Hence I decided to turn this serializer into a module called HashData. Other Serializing methods In PowerShell we have several possibilities to serialize objects. There are two cmdlets you can use which are built in: Export-CliXml ConvertTo-JSON Both are excellent options if you do not care about the size of the file. In my case I needed something lean and mean in terms of the size on disk for the serialized object. Lets do some tests to compare the different types: (Hashdata.Object.ps1) You might be curious why I do not use the Export-CliXML cmdlet and just use the [System.Management.Automation.PSSerializer]::Serialize static method.
