IWbs.GetCellValueFromWorkbook (String, Int32, Int32) Method
When you have few values to read from a workbook, prefer this rather than getting an instance of the complete workbook. This is usually faster because you don't have to acquire a lock on the workbook.
When referring to a merged area or a range, it returns the value being in the upper cell.
