What is the best way to work with xls files (x++)

I want to work with ".xls" files, however EPPlus produces an error when I try to read the ".xls" file.

this my code:

        System.IO.Stream stream;
        ExcelSpreadsheetName sheeet;
        FileUploadBuild fileUpload;
        DialogGroup dlgUploadGroup;
        FileUploadBuild fileUploadBuild;
        FormBuildControl formBuildControl;
        Dialog dialog = new Dialog("Import the data from Excel");
        dlgUploadGroup          = dialog.addGroup("@SYS54759");
        formBuildControl        = dialog.formBuildDesign().control(dlgUploadGroup.name());
        fileUploadBuild         = formBuildControl.addControlEx(classstr(FileUpload), 'Upload');
        fileUploadBuild.style(FileUploadStyle::MinimalWithFilename);
        fileUploadBuild.fileTypesAccepted('.xls');
 
        if (dialog.run() && dialog.closedOk())
        {
            FileUpload fileUploadControl     = dialog.formRun().control(dialog.formRun().controlId('Upload'));
            FileUploadTemporaryStorageResult fileUploadResult = fileUploadControl.getFileUploadResult();
 
            if (fileUploadResult != null && fileUploadResult.getUploadStatus())
            {
                stream = fileUploadResult.openResult();
                using (ExcelPackage Package = new ExcelPackage(stream))
                {
                    int rowCount, i;
                    Package.Load(stream);
                    ExcelWorksheet  worksheet   = package.get_Workbook().get_Worksheets().get_Item(1);
                    OfficeOpenXml.ExcelRange    range       = worksheet.Cells;
                    rowCount                  = worksheet.Dimension.End.Row - worksheet.Dimension.Start.Row   1;
 
                    for (i = 2; i<= rowCount; i  )
                    {
                        info(range.get_Item(i, 1).value);
                        info(range.get_Item(i, 2).value);
                    }
                }
            }
            else
            {
                error("Error here");
            }

I'm wondering whether there is another approach to work with "xls" files.

I saw several code snippets that use SysExcelWorkbook, but they fail with the error "The name 'SysExcelApplication' does not denote a class, a table, or an extended data type."

        SysExcelApplication application;
        SysExcelWorkbooks workbooks;
        SysExcelWorkbook workbook;
        SysExcelWorksheets worksheets;
        SysExcelWorksheet worksheet;
        SysExcelCells cells;
        COMVariantType type;
        int row;
        ItemId itemid;
        Name name;
        FileName filename;
        ;
        application = SysExcelApplication::construct();
        workbooks = application.workbooks();
        //specify the file path that you want to read
        filename = @"C:\Users\hsaoudi\Downloads\crypresenceetcoutparemploye.xls";
        try
        {
            workbooks.open(filename);
        }
        catch (Exception::Error)
        {
            throw error("File cannot be opened.");
        }
        workbook = workbooks.item(1);
        worksheets = workbook.worksheets();
        worksheet = worksheets.itemFromNum(1);
        cells = worksheet.cells();
        do
        {
            row  ;
            itemId = cells.item(row, 1).value().bStr();
            name = cells.item(row, 2).value().bStr();
            info(strfmt('%1 - %2', itemId, name));
            type = cells.item(row 1, 1).value().variantType();
        }
        while (type != COMVariantType::VT_EMPTY);
        application.quit();
