@MasterOfLogic Can you check if this code Works :
The error that you get is Mostly Because the GetSheets method doesn’t actually output an array of String, infact I don’t think there’s a GetSheets method on the Excel.Workbook class instead I think it’s called Sheets.

The WorkBook.Sheets() method outputs a Collection of WorkSheets present not the names, we need to loop each of the Worksheet and extract the name and then compare. Take a look at this code.
