C# - I want to convert a csv file to xlsx format on a server where office is not installed.

What I have tried:

//Using Interop
                //Application app = new Application();
                //Workbook wb = app.Workbooks.Open(Util.CSVFileName);
                //wb.SaveAs(Util.XLSXFileName, XlFileFormat.xlOpenXMLWorkbook, AccessMode: XlSaveAsAccessMode.xlExclusive);
                //wb.Close();
                //app.Quit();

Do you know that Excel can open a .csv file directly ?

Obviously, it is useless since Excel can open thise files. However, one need to ensure that refional settings are properly set as Excel assume system separator...

C#

if (File.Exists(Util.XLSXFileName))
                {
                    File.Delete(Util.XLSXFileName);
                }
                //Save as xlsx using Spire
                Workbook workbook = new Workbook();
                workbook.LoadFromFile(Util.CSVFileName, ",", 1, 1);
                Worksheet sheet = workbook.Worksheets[0];
                sheet.Name = "csv to excel";
                workbook.SaveToFile(Util.XLSXFileName, ExcelVersion.Version2010);

                //Delete Evaluation Warning using EPPlus
                var workbookFileInfo = new FileInfo(Util.XLSXFileName);
                using (var excelPackage = new ExcelPackage(workbookFileInfo))
                {
                    var worksheet = excelPackage.Workbook.Worksheets.SingleOrDefault(x => x.Name == "Evaluation Warning");
