I am exporting the gridview data to the excel file in c# .

C#

protected void btnExportExcel_Click(object sender, EventArgs e)
{
Response.Clear();
Response.Buffer = true;
 
Response.AddHeader("content-disposition",
"attachment;filename=GridViewExport.xls");
Response.Charset = "";
Response.ContentType = "application/vnd.ms-excel";
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
 
GridView1.AllowPaging = false;
GridView1.DataBind();
 
//Change the Header Row back to white color
GridView1.HeaderRow.Style.Add("background-color", "#FFFFFF");
 
//Apply style to Individual Cells
GridView1.HeaderRow.Cells[0].Style.Add("background-color", "green");
GridView1.HeaderRow.Cells[1].Style.Add("background-color", "green");
GridView1.HeaderRow.Cells[2].Style.Add("background-color", "green");
GridView1.HeaderRow.Cells[3].Style.Add("background-color", "green");  
 
for (int i = 0; i < GridView1.Rows.Count;i++ )
{
    GridViewRow row = GridView1.Rows[i];
 
    //Change Color back to white
    row.BackColor = System.Drawing.Color.White;
 
    //Apply text style to each Row
    row.Attributes.Add("class", "textmode");
 
    //Apply style to Individual Cells of Alternating Row
    if (i % 2 != 0)
    {
        row.Cells[0].Style.Add("background-color", "#C2D69B");
        row.Cells[1].Style.Add("background-color", "#C2D69B");
        row.Cells[2].Style.Add("background-color", "#C2D69B");
        row.Cells[3].Style.Add("background-color", "#C2D69B");  
    }
}
GridView1.RenderControl(hw);
 
//style to format numbers to string
string style = @"<style> .textmode { mso-number-format:\@; } </style>";
Response.Write(style);
Response.Output.Write(sw.ToString());
Response.Flush();
Response.End();
}

Replace the code

Response.Output.Write(sw.ToString());

with the below code

C#

StringBuilder sSchema = new StringBuilder();
sSchema.Append("<html xmlns:v=\"urn:schemas-microsoft-com:vml\" xmlns:o=\"urn:schemas-microsoft-com:office:office\" xmlns:x=\"urn:schemas-microsoft-com:office:excel\" xmlns=\"http://www.w3.org/TR/REC-html40\"> <head><meta http-equiv=\"Content-Type\" content=\"text/html;charset=windows-1252\"><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet><x:Name>ExportToExcel</x:Name><x:WorksheetOptions><x:Panes></x:Panes></x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></head> <body>");
sSchema.Append(sw.ToString() + "</body></html>");
Response.Output.Write(sSchema.ToString());

so your final code will be

protected void btnExportExcel_Click(object sender, EventArgs e)
{
Response.Clear();
Response.Buffer = true;
 
Response.AddHeader("content-disposition",
"attachment;filename=GridViewExport.xls");
Response.Charset = "";
Response.ContentType = "application/vnd.ms-excel";
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
 
GridView1.AllowPaging = false;
GridView1.DataBind();
 
//Change the Header Row back to white color
GridView1.HeaderRow.Style.Add("background-color", "#FFFFFF");
 
//Apply style to Individual Cells
GridView1.HeaderRow.Cells[0].Style.Add("background-color", "green");
GridView1.HeaderRow.Cells[1].Style.Add("background-color", "green");
GridView1.HeaderRow.Cells[2].Style.Add("background-color", "green");
GridView1.HeaderRow.Cells[3].Style.Add("background-color", "green");  
 
for (int i = 0; i < GridView1.Rows.Count;i++ )
{
    GridViewRow row = GridView1.Rows[i];
 
    //Change Color back to white
    row.BackColor = System.Drawing.Color.White;
 
    //Apply text style to each Row
    row.Attributes.Add("class", "textmode");
 
    //Apply style to Individual Cells of Alternating Row
    if (i % 2 != 0)
    {
        row.Cells[0].Style.Add("background-color", "#C2D69B");
        row.Cells[1].Style.Add("background-color", "#C2D69B");
        row.Cells[2].Style.Add("background-color", "#C2D69B");
        row.Cells[3].Style.Add("background-color", "#C2D69B");  
    }
}
GridView1.RenderControl(hw);
 
//style to format numbers to string
string style = @"<style> .textmode { mso-number-format:\@; } </style>";
Response.Write(style);
StringBuilder sSchema = new StringBuilder(); 
sSchema.Append("<html xmlns:v=\"urn:schemas-microsoft-com:vml\" xmlns:o=\"urn:schemas-microsoft-com:office:office\" xmlns:x=\"urn:schemas-microsoft-com:office:excel\" xmlns=\"http://www.w3.org/TR/REC-html40\"> <head><meta http-equiv=\"Content-Type\" content=\"text/html;charset=windows-1252\"><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet><x:Name>ExportToExcel</x:Name><x:WorksheetOptions><x:Panes></x:Panes></x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></head> <body>"); 
sSchema.Append(sw.ToString() + "</body></html>");  
Response.Output.Write(sSchema.ToString());
Response.Flush();
Response.End();
}
