If you are reading data from Excel file, you can use EPPlus NuGet package, and use following code:

//using OfficeOpenXml;
using (ExcelPackage xlPackage = new ExcelPackage(new FileInfo(@"C:\YourDirectory\sample.xlsx")))
{
    var myWorksheet = xlPackage.Workbook.Worksheets.First(); //select sheet here
    var totalRows = myWorksheet.Dimension.End.Row;
    var totalColumns = myWorksheet.Dimension.End.Column;

    var sb = new StringBuilder(); //this is your data
    for (int rowNum = 1; rowNum <= totalRows; rowNum++) //select starting row here
    {
        var row = myWorksheet.Cells[rowNum, 1, rowNum, totalColumns].Select(c => c.Value == null ? string.Empty : c.Value.ToString());
        sb.AppendLine(string.Join(",", row));
    }
}
