ListObject.Refresh (Excel)
Retrieves the current data and schema for the list from the server that is running Microsoft SharePoint Foundation. This method can be used only with lists that are linked to a SharePoint site. If the SharePoint site is not available, calling this method returns an error.
Calling the Refresh method does not commit changes to the list in the Excel workbook. Uncommitted changes in the list in Excel are discarded when the Refresh method is called.
