Import Excel Data Into An ASP.NET GridView using OLEDB

I have seen a lot of users asking how to import data from an excel sheet into an ASP.NET GridView.

I will show two ways to do so - Using OLEDB and Using Microsoft.Office.Interop.Excel

In this post, we will see how to import data using OLEDB


using System.Data.OleDb;
using System.Data;

public partial class UploadD : System.Web.UI.Page
protected void Page_Load(object sender, EventArgs e)
string cnstr = "Provider=Microsoft.Jet.Oledb.4.0;Data Source=C:\a.xls;"
+ "Extended Properties=Excel 8.0";
OleDbConnection oledbConn = new OleDbConnection(cnstr);
string strSQL = "SELECT * FROM [Sheet$]";

OleDbCommand cmd = new OleDbCommand(strSQL, oledbConn);
DataSet ds = new DataSet();
OleDbDataAdapter da = new OleDbDataAdapter(cmd);
GridView1.DataSource = ds;


Imports System.Data.OleDb
Imports System.Data

Partial Public Class UploadD
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
Dim cnstr As String = "Provider=Microsoft.Jet.Oledb.4.0;" &_
"Data Source=C:\a.xls; Extended Properties=Excel 8.0"
Dim oledbConn As New OleDbConnection(cnstr)
Dim strSQL As String = "SELECT * FROM [Sheet$]"

Dim cmd As New OleDbCommand(strSQL, oledbConn)
Dim ds As New DataSet()
Dim da As New OleDbDataAdapter(cmd)
GridView1.DataSource = ds
End Sub
End Class

I am using OLEDB providers and have some problems with some Excel files - not getting the last row unless the worksheet is open in Excel. I wonder if you have seen this issue?

Is there a variation of this that does use OLEDB but does not require a physical file path but takes string input (CSV) instead?
