Imports System.Data.SqlClient

Public Class MainForm

    Private Sub BtnImpExcelFile_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnImpExcelFile.Click
    Dim conn As OleDbConnection

    Dim dta As OleDbDataAdapter

    Dim dts As DataSet
    Dim excel As String
    Dim OpenFileDialog As New OpenFileDialog

    OpenFileDialog.InitialDirectory = My.Computer.FileSystem.SpecialDirectories.MyDocuments
    OpenFileDialog.Filter = "All Files (*.*)|*.*|Excel files (*.xlsx)|*.xlsx|CSV Files (*.csv)|*.csv|XLS Files (*.xls)|*xls"

    If (OpenFileDialog.ShowDialog(Me) = System.Windows.Forms.DialogResult.OK) Then

        Dim fi As New FileInfo(OpenFileDialog.FileName)
        Dim FileName As String = OpenFileDialog.FileName

        excel = fi.FullName
        conn = New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + excel + ";Extended Properties=Excel 12.0;")
        dta = New OleDbDataAdapter("Select * From [Sheet1$]", conn)
        dts = New DataSet
        dta.Fill(dts, "[Sheet1$]")
        DGVImpData.DataSource = dts
        DGVImpData.DataMember = "[Sheet1$]"
        conn.Close()
    End If
End Sub

End Class

Saving data from excel file to database will require a proper connection string to your database. Then on the button click you should add the code that will do the insert. Kindly check this tutorial which doest the exact thing - How to Import Excel File into Database in ASP.NET MVC
