Export Import Excel Data into Sql Server Using SqlBulkCopy-ASP.NET

Export Import Excel Data into Sql Server Using SqlBulkCopy-ASP.NET

In this example i am going to describe how to Import or insert data into Sql server from Excel spreadsheet using sqlbulkcopy method.

First of all create a Excel workbook as shown in image below and insert some data into it.


Create a table in SQL database as shown in image


Now write this code to insert data into SQL table
public partial class _Default : System.Web.UI.Page
{
string strConnection = ConfigurationManager.ConnectionStrings
["ConnectionString"].ConnectionString;
protected void Page_Load(object sender, EventArgs e)
{

}
protected void Button1_Click(object sender, EventArgs e)
{
//Create connection string to Excel work book
string excelConnectionString =
@"Provider=Microsoft.Jet.OLEDB.4.0;
Data Source=C:\Details.xls;
Extended Properties=""Excel 8.0;HDR=YES;""";

//Create Connection to Excel work book
OleDbConnection excelConnection =
new OleDbConnection(excelConnectionString);

//Create OleDbCommand to fetch data from Excel
OleDbCommand cmd = new OleDbCommand
("Select [ID],[Name],[Location] from [Detail$]",
excelConnection);

excelConnection.Open();
OleDbDataReader dReader;
dReader = cmd.ExecuteReader();

SqlBulkCopy sqlBulk = new SqlBulkCopy(strConnection);
sqlBulk.DestinationTableName = "Details";
//sqlBulk.ColumnMappings.Add("ID", "ID");
//sqlBulk.ColumnMappings.Add("Name", "Name");
sqlBulk.WriteToServer(dReader);
}
}


If there are more columns in your database table or excel workbook and you want to insert data in some of them than you need to add ColumnMappings like this
sqlBulk.ColumnMappings.Add("ID", "ID");
sqlBulk.ColumnMappings.Add("Name", "Name");


End result will be like this


Hope this helps
