How do I directly refer to a cell within an Excel workbook from a presentation?
Cells within an Excel workbook can be directly referred
using the file name with Excel's native naming scheme:
<filename>#<sheet>!$<row>$<col>
For example, for linking to cell A1 of Sheet2
within the file microsoft.xls, you would use microsoft.xls#Sheet2!$A$1
as the hyperlink text to take you directly to that cell.
