Is it possible to create an excel file and open it, without saving it first to server or local location. I'm trying to acheive this.

using Microsoft.Office.Interop;
using Excel = Microsoft.Office.Interop.Excel;

protected void btnOpen_Click(object sender, EventArgs e)
{
  OpenExcel();
}

private void OpenExcel()
{
  Excel.Application app = new Excel.Application();
  Excel.Workbook wb = new Excel.Workbook();
  Excel.Worksheet ws = new Excel.Worksheet();
  Excel.Range range = null;

  app.visible = true;
  wb = app.Workbooks.Add(1);
  ws = wb.WorkSheets[1];
  range = ws.get_Range("A1","A3");
  
   ws.Cells[0,0]="Date";
   ws.Cells[0,1]="Code";
   ws.Cells[0,2]="Name";
  
}

Yes, the code is very much incomplete. The idea is to pop up an excel sheet (of certain template), to the user on button click. Could someone guide me, how I should proceed from here.

0	It was all there and I didn't know. For beginers like me, hope this helps. This Code will create a template in an excel sheet and open on a button click. The template chosen here is just a header with col. names. Another important thing to note is, Office.Interop indexing starts from 1 instead of 0. using Microsoft.Office.Interop; using Excel = Microsoft.Office.Interop.Excel; protected void btnOpen_Click(object sender, EventArgs e) { OpenExcel(); } private void OpenExcel() { Excel.Application app = new Excel.Application(); Excel.Workbook wb = null; Excel.Worksheet ws = null; Excel.Range range = null; app.visible = true; wb = app.Workbooks.Add(1); ws = (Excel.Worksheet)wb.WorkSheets[1]; range = ws.get_Range("A1","D1"); ws.Cells[1,1]="Date"; ws.Cells[1,2]="Code"; ws.Cells[1,3]="Name"; app.Rows.AutoFit(); app.Columns.AutoFit(); range.Borders.Color = System.Drawing.Color.Black.ToArgb(); range.Interior.Color = System.Drawing.Color.PeachPuff.ToArgb(); range.Font.Bold = true; } Sharpcnet, if this helps please login to Mark As Answer. \| Alert Moderator
