            int linkIndex = workbook.Worksheets.ExternalLinks.Add(DirectoryType.Volume, externalFileName, sheetNames);

            // Retrieve the added external link
            ExternalLink externalLink = workbook.Worksheets.ExternalLinks[linkIndex];

            // Output the details of the external link
