Insert cell data in an Excel file using OLEDB in VB.net
 


In this article we can see how to insert data into Excel file, without using Excel Object we can insert, edit, delete, select etc. in cell content of an Excel 2007 file using OLEDB in VB.NET 2005. Here we are using OleDbConnection, OleDbDataAdapter, and DataSet for doing these operations in an Excel file. You have to import System.Data in the project for doing these operations. For add new content in the cell or insert a new content, we can use the INSERT command like in SQL Operations.

sample UPDATE sql
sql = "Insert into [Sheet1$] (id,name) values('5','e')" 
The follwoing picture shows before and after update of the Sheet.

Imports System.Data

Public Class Form1

    Private Sub Button1_Click(ByVal sender As System.Object, _
                ByVal e As System.EventArgs) Handles Button1.Click
        Try

            Dim MyConnection As System.Data.OleDb.OleDbConnection
            Dim myCommand As New System.Data.OleDb.OleDbCommand
            Dim sql As String

            MyConnection = New System.Data.OleDb.OleDbConnection _
            ("provider=Microsoft.Jet.OLEDB.4.0; Data Source=" + _
            "'c:\testfile.xls';Extended Properties=Excel 8.0;")

            MyConnection.Open()
            myCommand.Connection = MyConnection
            sql = "Insert into [Sheet1$] (id,name) values('5','e')"
            myCommand.CommandText = sql
            myCommand.ExecuteNonQuery()
            MyConnection.Close()

        Catch ex As Exception
            MsgBox(ex.ToString)
        End Try

        MsgBox("Row Added ")

    End Sub

End Class
When you execute this source code it will insert a row in the Excel file.
