Question

I have this C# code which converts a dataset to xlsx. Is there a way to set the cell or column width of the sheet of the xlsx file created?

//Get the filename      
String filepath = args[0].ToString();
//Convert the file to dataset
DataSet ds = Convert(filepath.ToString(), "tblCustomers", "\t");

//Create the excell object
Excel.Application excel = new Excel.Application();
//Create the workbook
Excel.Workbook workBook = excel.Workbooks.Add();
//Set the active sheet
Excel.Worksheet sheet = workBook.ActiveSheet;


int i = 0;
foreach (DataRow row in ds.Tables[0].Rows)
{                              
    for (int j = 0; j < row.ItemArray.Length; j++)
    {
        sheet.Cells[i + 1, j + 1] = row[j];
    }

    i++;
}

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

Answer 1

sheet.Columns["D:D"].ColumnWidth = 17.57;

or

sheet.Columns[1].ColumnWidth = 17.57;

You can record Macros in Excel and then look to generated code (object model is the same).
