Solution 1
Use EPPlus. It allows you to create Excel spreadsheets on the server. I've used it and it worked great. It supports advanced functions.
using (ExcelPackage pck = new ExcelPackage())
{
//Create the worksheet
ExcelWorksheet ws = pck.Workbook.Worksheets.Add("Demo");
//Load the datatable into the sheet, starting from cell A1. Print the column names on row 1
ws.Cells["A1"].LoadFromDataTable(tbl, true);
//Format the header for column 1-3
using (ExcelRange rng = ws.Cells["A1:C1"])
{
rng.Style.Font.Bold = true;
rng.Style.Fill.PatternType = ExcelFillStyle.Solid;
//Set Pattern for the background to Solid
rng.Style.Fill.BackgroundColor.SetColor(Color.FromArgb(79, 129, 189));
//Set color to dark blue
rng.Style.Font.Color.SetColor(Color.White);
}
//Example how to Format Column 1 as numeric
using (ExcelRange col = ws.Cells[2, 1, 2 + tbl.Rows.Count, 1])
{
col.Style.Numberformat.Format = "#,##0.00";
col.Style.HorizontalAlignment = ExcelHorizontalAlignment.Right;
}
//Write it back to the client
Response.Clear();
Response.AddHeader("content-disposition", "attachment; filename=file.xlsx");
Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
Response.BinaryWrite(pck.GetAsByteArray());
Response.End();
}

The most flexible and likely to do exactly what you need is going to take some work, but it's free -- and really works. Use the toolkit to look at existing documents to see how to create the features you want.

I need to generate an excel file for a user on the fl upon button click. I was using Netoffice before which worked fine for desktop applications. But now I want to do the same thing with an asp.net app. This way my server code doesn't have an access to the client's copy of excel. What approach should I take?
