reading a csv file with excel from c# RRS feed

  • Question

  • Hi,

    I am trying to convert a csv and text files to an excel file from c#.

    I am trying to open them with excel, then save them.

    I find a file at the end of the execution but it's not taking into consideration the seperator.

                        Microsoft.Office.Interop.Excel.Application app = new Microsoft.Office.Interop.Excel.Application();
                        app.DisplayAlerts = false;
                        string FilePathToTreat = this.Search(workingDirectoryv1, FileNameToTreat);
                        //Microsoft.Office.Interop.Excel.Workbook excelWorkbook = app.Workbooks.Open(FilePathToTreat);

                        Microsoft.Office.Interop.Excel.Workbook excelWorkbook = app.Workbooks.Open(FilePathToTreat, 0, false, Excel.XlFileFormat.xlCSV, "", "", false, Excel.XlPlatform.xlWindows, charseparator, true, false, 0, true, false, false);
                        string newFileName = pathtemp1 + Path.GetFileNameWithoutExtension(FilePathToTreat) + ".xlsx";


    Would you please help ?

    Thank you for your time

  • Hello,

    Tried, but didn't work ....

    I think the problem is with the open more than it is with the save

    Thank you for your time!

  • You could probably try Spire.XLS, it is capable of covnerting CSV and Text files to Excel documents

    how to convert CSV to Excel:

    using Spire.Xls;
    namespace csvtoxls
        class Program
            static void Main(string[] args)
             Workbook workbook = new Workbook();
             workbook.LoadFromFile(@"D:\michelle\my file\csv2xls.csv", ",", 1, 1);
             Worksheet sheet = workbook.Worksheets[0];
             sheet.Name = "csv to excel";
             workbook.SaveToFile("result.xls", ExcelVersion.Version2010);
