Update Excel Database Records
Converting Excel `WorkBook.ToDataSet()` allows .Net developers to first manipulate the dataset, and then use it to update SQL records very easily using `System.Data`.
using System.Data;
using System.Data.SqlClient;
using IronXL;
WorkBook wb = WorkBook.Load("test.xlsx");
DataSet dataSet = wb.ToDataSet();
//Your sql query
string sql = "SELECT * FROM Users";
//Your connection string
string connectionString = @"Data Source=.\SQLEXPRESS;Initial Catalog=usersdb;Integrated Security=True";
using (SqlConnection connection = new SqlConnection(connectionString))
{
//Open connections to the database
connection.Open();
SqlDataAdapter adapter = new SqlDataAdapter(sql, connection);
//Important - you can (and probably should) modify / crop the data in the dataset here to match the shape of your SQL query
//Update the values in database using the values in Excel
adapter.Update(dataSet);
}

Private wb As WorkBook = WorkBook.Load("test.xlsx")
Private dataSet As DataSet = wb.ToDataSet()

adapter.Update(dataSet)
End Using
