How do I read the cell comments from an Excel spreadsheet using Powershell

I have a spreadsheet that I need to load into a database.  Some of the information needed is saved in the cell comments.  In my test spreadsheet there is a comment on the first column A1.

So far I have tried:
write-host $ExcelWorkSheet.Range("A1"

write-host $ExcelWorkSheet.Range("R1,C1").Offset(1,0).NoteText

I receive back either nothing or (Variant, Variant, Variant)

Is there any way to get to the cell comments through Powershell
