That really depends on what you mean by creating a PS object of it. If you just remove the portion that sets the value in the excel document, then it will return the value to the pipeline instead. This would be a string object. If you are looking to create a custom powershell object with properties, then you would just need to define that and it would output.
Obviously the above is not very useful since it is outputting the same thing for in every case. It would be good to provide a sample of what you are wanting to see so we can better understand what you are trying to accomplish.
