Answer 1

I was having the same problem with my CSV to be transformed. I was able to do this in a little different manner.

private string ConvertToExcel(string CSVpath, string EXCELPath)
    {
        try
        {
            string Filename = System.IO.Path.GetFileNameWithoutExtension(CSVpath);
            string DirectoryName = System.IO.Path.GetDirectoryName(CSVpath);
            EXCELPath = DirectoryName + "\\" + Filename + ".xlsx";

            string worksheetsName = "Report";
            bool firstRowIsHeader = false;

            var format = new OfficeOpenXml.ExcelTextFormat();
            format.Delimiter = '|';
            format.EOL = "\n";

            using (OfficeOpenXml.ExcelPackage package = new OfficeOpenXml.ExcelPackage(new System.IO.FileInfo(EXCELPath)))
            {
                string dateformat = "m/d/yy h:mm";
                //string dateformat = System.Globalization.DateTimeFormatInfo.CurrentInfo.ShortDatePattern;

                OfficeOpenXml.ExcelWorksheet worksheet = package.Workbook.Worksheets.Add(worksheetsName);
                worksheet.Cells["A1"].LoadFromText(new System.IO.FileInfo(CSVpath), format, OfficeOpenXml.Table.TableStyles.Medium2, firstRowIsHeader);

                worksheet.Column(3).Style.Numberformat.Format = dateformat;
                worksheet.Column(5).Style.Numberformat.Format = dateformat;
                worksheet.Column(6).Style.Numberformat.Format = dateformat;
                worksheet.Column(20).Style.Numberformat.Format = dateformat;
                worksheet.Column(21).Style.Numberformat.Format = dateformat;
                worksheet.Column(22).Style.Numberformat.Format = dateformat;




                package.Save();
            }
        }
        catch (Exception ex)
        {
            //DAL.Operations.Logger.LogError(ex);
            Console.WriteLine(ex);
            Console.Read();
        }
        return EXCELPath;
    }
