Convert CSV into XLS

Question

I\'m working in a web application separated in blocks and I\'m getting a CSV object from a work mate of mine which I must convert into XLS to be passed into an Excel Process

Answer 1

It should be easy for you to convert the CSV object into an array of arrays of strings and then do like in the following example (you'll need to add a reference to Microsoft.Office.Interop.Excel):

using Excel = Microsoft.Office.Interop.Excel;

Excel.Application excel = new Excel.Application();
Excel.Workbook workBook = excel.Workbooks.Add();
Excel.Worksheet sheet = workBook.ActiveSheet;

var CsvContent = new string[][]
{
    new string[] {"FirstName", "UserName", "PostCode", "City"},
    new string[] {"John", "Smith", "4568", "London"},
    new string[] {"Brian", "May", "9999", "Acapulco"}
};

for (int i = 0; i < CsvContent.Length; i++)
{
    string[] CsvLine = CsvContent[i];
    for (int j = 0; j < CsvLine.Length; j++)
    {
        sheet.Cells[i + 1, j + 1] = CsvLine[j];
    }
}

workBook.SaveAs(@"C:\Temp\fromCsv.xls");
workBook.Close();
