conn.Close(); return dtexcel; }


It works same as in case of database.like


OleDbConnection cnn = new OleDbConnection(@"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + Server.MapPath(@"~\data\cocustomerdetails.xlsx") + "; Extended Properties=Excel 12.0;"); OleDbCommand oconn = new OleDbCommand("select * from [Sheet1$]", cnn); cnn.Open(); OleDbDataAdapter adp = new OleDbDataAdapter(oconn); DataTable dt = new DataTable(); adp.Fill(dt);

Hello,It is very easy to export excel data into datatable using [Commercial Spam Link Removed]. Take a lookat this C# example:


ExcelWorkbook Wbook = ExcelWorkbook.ReadXLS(@"c:\test.xls");ExcelWorksheet Wsheet = Wbook.Worksheets["Sheet3"];DataTable dt = new DataTable();dt = Wsheet.WriteToDataTable();

You can use below code:


namespace DataFromWorkbookToDB{ class Program { static void Main(string[] args) { Workbook workbook = new Workbook(); workbook.LoadFromFile(@"..\..\Sample.xlsx"); string connStr = "Provider=Microsoft.ACE.OLEDB.12.0;data Source=sample.accdb;Persist Security Info=False;"; DataTable dt = workbook.Worksheets[0].ExportDataTable(); DataTable dt2 = workbook.Worksheets[1].ExportDataTable(); using (OleDbConnection conn = new OleDbConnection(connStr)) { conn.Open(); OleDbCommand command = new OleDbCommand(); command.Connection = conn; command.CommandText = "CREATE TABLE report(Name VARCHAR(225), Capital VARCHAR(225) ,Continent VARCHAR(225),Area VARCHAR(225),Population VARCHAR(225))"; command.ExecuteNonQuery(); command.CommandText = "CREATE TABLE lists(PartNo VARCHAR(225), VendorNo VARCHAR(225) ,Description VARCHAR(225),OnHand VARCHAR(225),OnOrder VARCHAR(225))"; command.ExecuteNonQuery(); for (int i = 0; i < dt.Rows.Count; i++) { DataRow row = dt.Rows[i]; string commd = "insert into [report](Name,Capital,Continent,Area,Population) values('" + row[0].ToString() + "','" + row[1].ToString() + " ','" + row[2].ToString() + "','" + row[3].ToString() +"','"+ row[4].ToString() + "')"; command.CommandText = commd; command.ExecuteNonQuery(); } for (int i = 0; i < dt2.Rows.Count; i++) { DataRow row = dt2.Rows[i]; string commd = "insert into [lists](PartNo,VendorNo,Description,OnHand,OnOrder) values('" + row[0].ToString() + "','" + row[1].ToString() + " ','" + row[2].ToString() + "','" + row[3].ToString() + "','" + row[4].ToString() + "')"; command.CommandText = commd; command.ExecuteNonQuery(); } } } }}

please note that above code needs this excel library Spire.XLS for .NET, you can give it a try,
