   void Page_Load(object sender, EventArgs e) {
   
       string ConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0; Data Source=D:\spreadsheet.xls; Extended Properties=""Excel 8.0;HDR=Yes"";";
       string CommandText = "select * from [Book$]";
   
       OleDbConnection myConnection = new OleDbConnection(ConnectionString);
       OleDbCommand myCommand = new OleDbCommand(CommandText, myConnection);
   
       myConnection.Open();
   
       DataGrid1.DataSource = myCommand.ExecuteReader(CommandBehavior.CloseConnection);
       DataGrid1.DataBind();
   
       myConnection.Close();
   }

</script> <html> <head> </head> <body> 

   <form runat="server">
       <asp:datagrid id="DataGrid1" runat="server" EnableViewState="False" ForeColor="Black" BackColor="White" CellPadding="3" GridLines="None" CellSpacing="1">
           <HeaderStyle font-bold="True" forecolor="white" backcolor="#4A3C8C"></HeaderStyle>
           <ItemStyle backcolor="#DEDFDE"></ItemStyle>

Use OleDbCommand to retrieve data from Excel data source

   <source lang="csharp">

<%@ Page Language="C#" %> <%@ import Namespace="System.Data" %> <%@ import Namespace="System.Data.OleDb" %> <script runat="server"> 

   void Page_Load(object sender, EventArgs e) {
   
       string ConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0; Data Source=D:\spreadsheet.xls; Extended Properties=""Excel 8.0;HDR=Yes"";";
       string CommandText = "select * from [Book$]";
   
       OleDbConnection myConnection = new OleDbConnection(ConnectionString);
       OleDbCommand myCommand = new OleDbCommand(CommandText, myConnection);
   
       myConnection.Open();
   
       DataGrid1.DataSource = myCommand.ExecuteReader(CommandBehavior.CloseConnection);
       DataGrid1.DataBind();
   
       myConnection.Close();
   }

</script> <html> <head> </head> <body> 

   <form runat="server">
       <asp:datagrid id="DataGrid1" runat="server" EnableViewState="False" ForeColor="Black" BackColor="White" CellPadding="3" GridLines="None" CellSpacing="1">
           <HeaderStyle font-bold="True" forecolor="white" backcolor="#4A3C8C"></HeaderStyle>
