The problem is that I need to insert data into Excel from the collection several times using a single template for the entire collection. using (var pckg = new ExcelPackage(new FileInfo(association.TemplatePath))) { var workSheet = pckg.Workbook.Worksheets[1]; var dataTable = WorksheetToDataTable(workSheet); /*Some stuff*/ FindAndReplaceValue(workSheet, dictionary, row); } private DataTable WorksheetToDataTable(ExcelWorksheet oSheet) { int totalRows = oSheet.Dimension.End.Row; int totalCols = oSheet.Dimension.End.Column; DataTable dt = new DataTable(oSheet.Name); DataRow dr = null; for (int i
