<title>Read and Display Data From an Excel File (.xsl or .xlsx) in ASP.NET</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<b>Please Select Excel File: </b>
<asp:FileUpload ID="fileuploadExcel" runat="server" />
<asp:Button ID="btnImport" runat="server" Text="Import Data" OnClick="btnImport_Click" />
<br />
<asp:Label ID="lblMessage" runat="server" Visible="False" Font-Bold="True" ForeColor="#009933"></asp:Label><br />

<HeaderStyle BackColor="#df5015" Font-Bold="true" ForeColor="White" />
</asp:GridView>
</div>
</form>

Now open code behind file and add the following namespaces
using System;
using System.Data;
using System.Data.OleDb;
using System.IO;
After that write the following code in code behind
C#.NET Code
protected void btnImport_Click(object sender, EventArgs e)
{
string connString = "";
string strFileType = Path.GetExtension(fileuploadExcel.FileName).ToLower();
string path = fileuploadExcel.PostedFile.FileName;
//Connection String to Excel Workbook
if (strFileType.Trim() == ".xls")
{
connString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + path + ";Extended Properties=\"Excel 8.0;HDR=Yes;IMEX=2\"";
}
else if (strFileType.Trim() == ".xlsx")
{
connString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + path + ";Extended Properties=\"Excel 12.0;HDR=Yes;IMEX=2\"";
}
string query = "SELECT [UserName],[Education],[Location] FROM [Sheet1$]";
OleDbConnection conn = new OleDbConnection(connString);
if (conn.State == ConnectionState.Closed)
conn.Open();
OleDbCommand cmd = new OleDbCommand(query, conn);
OleDbDataAdapter da = new OleDbDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);
grvExcelData.DataSource = ds.Tables[0];
grvExcelData.DataBind();
da.Dispose();
conn.Close();
conn.Dispose();
}
NOTE: To test above example, Create Excel file named as "TestExcel" with Sheet1 and columns UserName, Education, Location
