Import Excel Data To SQL Using C#

In this post , We will learn how to Import excel data to SQL using C# with the help of OLEDB . This is a time saver especially if you want to add tons and tons of data to your table within a fraction of second a so let’s get started.

First thing first , Create a table in SQL-Server database (you can copy paste following code to your SQL-Server to relate flawless with the following article).

CREATE TABLE [dbo].[tbl_registration](
[Sr_no] [int] IDENTITY(1,1) NOT NULL,
[Email] [nvarchar](100) NULL,
[Password] [nvarchar](max) NULL,
[Name] [varchar](max) NULL,
[Address] [nvarchar](max) NULL,
[City] [nvarchar](max) NULL

Now, Add connection string to your Web.config file.

   <add name="con" connectionString="Server=YourServerName;Initial Catalog=YourDatabaseName;Persist Security Info=False;User ID=YourUserName;Password=YourUserPassword;MultipleActiveResultSets=True;Encrypt=False;TrustServerCertificate=False;Connection Timeout=30;" providerName="System.Data.SqlClient" />

Note :- Change Server,Initial Catalog,User ID,Password values as per your server properties

Now, Add the following code to your Index.cshtml file

<!DOCTYPE html>
    <meta name="viewport" content="width=device-width" />
        <h2>Excel Import</h2>
        <form method="post" enctype="multipart/form-data" class="form-group">
                <input name="file" type="file" class="form-control-file" required />
                <button type="submit" class="btn btn-primary">Import</button>

Next step , Add Following Code to your Home Controller

SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["con"].ConnectionString);
        OleDbConnection econ;
        public ActionResult Index()
            return View();

        public ActionResult Index(HttpPostedFileBase file)
            string filename = Guid.NewGuid() + Path.GetExtension(file.FileName);
            string filepath = "/excelfolder/" + filename;
            file.SaveAs(Path.Combine(Server.MapPath("/excelfolder"), filename));
            InsertExceldata(filepath, filename);
            return View();
        private void ExcelConn(string filepath)
            string constr = string.Format(@"Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties=""Excel 12.0 Xml;HDR=YES;""", filepath);
            econ = new OleDbConnection(constr);            

        private void InsertExceldata(string fileepath, string filename)
            string fullpath = Server.MapPath("/excelfolder/") + filename;
            string query = string.Format("Select * from [{0}]", "Sheet1$");
            OleDbCommand ecom = new OleDbCommand(query, econ);
            DataSet ds = new DataSet();
            OleDbDataAdapter oda = new OleDbDataAdapter(query, econ);
            DataTable dt = ds.Tables[0];
            SqlBulkCopy objbulk = new SqlBulkCopy(con);
            objbulk.DestinationTableName = "tbl_registration";
            objbulk.ColumnMappings.Add("Email", "Email");
            objbulk.ColumnMappings.Add("Password", "Password");
            objbulk.ColumnMappings.Add("Name", "Name");
            objbulk.ColumnMappings.Add("Address", "Address");
            objbulk.ColumnMappings.Add("City", "City");

Note :- Add a folder namely excelfolder in your project.

And that’s it You can run the Project
