First need to add the reference “Microsoft.office.Interop.Excel”. You can add it from .Net Components. Add open Dialogbox ,Textbox and two command button on form.

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Windows.Forms;

using System.Data.OleDb;

using System.Data.SqlClient;

using System.IO;

namespace ExcelTOSQLDataBase

{

public partial class EXCELTOSQL : Form

{

publicEXCELTOSQL()

{

InitializeComponent();

}

privatevoid button1_Click(objectsender, EventArgs e)

{

if(openFileDialog1.ShowDialog() == DialogResult.OK)

textBox1.Text = openFileDialog1.FileName;

}

privatevoid button2_Click(objectsender, EventArgs e)

{

//Table Name

stringEXCELSQLTable = “Employees”;

stringExcelData = “Select * from [Sheet1$]”;

//SQL Server Connection String

string SQLConnectionString = “Data Source=ComputerName;Initial

Catalog=DataBaseName;Integrated Security=True”;

//Excel File Path

stringExcelFilePath=textBox1.Text;

try

{

string ConnectionString =@”Provider=Microsoft.Jet.OLEDB.4.0;Data Source=” + ExcelFilePath + “;Extended Properties=” + “”Excel 8.0;HDR=YES;””;

OleDbConnection OleDbCnn = new OleDbConnection(ConnectionString);

OleDbCnn.Open();

SqlBulkCopybulkCopy = new SqlBulkCopy(SQLConnectionString);

bulkCopy.DestinationTableName = EXCELSQLTable;

using (OleDbDataAdapterX = new OleDbDataAdapter(ExcelData, OleDbCnn))

{

DataTable SQLT = newDataTable();

X.Fill(SQLT);

bulkCopy.WriteToServer(SQLT);

}

OleDbCnn.Close();

MessageBox.Show(“Data Imported Successfully”);

}

catch (Exception ee)

{

label2.Text = ee.Message;

}
