Hi all,I am new to Excel used in SP and I have some dummy questions:1) Excel workbook is powerful for data calculation and I know we can publish an Excel file to the Portal. Can we just publish an Excel file and keep all the original calculations there and use them in the porta?2) Can I create a connectoin between a local Excel file and a published Excel table and synchronize something I write into the local workbook and refreshed in portal Excel?3) some links for Excel with SharePoint portal, for tutorials, blogs will be greately appreciated.Thanks in advance.allan
