View excel table in datagridview windows forms

Hello! my question is: can an excel table be displayed in a windows forms datagridview with the DbDataAdapter.Fill method?
below I attach the code that I achieve, the problem is that when executing the script revit and dynamo are closed
I also attach the source from where I interpret the code

code:

import clr

#add a reference 
clr.AddReference("System.Drawing")
clr.AddReference("System.Windows.Forms")
clr.AddReference("Microsoft.Office.Interop.Excel, Version=11.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c") 
clr.AddReference("System.Data") #para datagridview

#import library
import System.Drawing
import System.Windows.Forms
import Microsoft.Office.Interop.Excel as Excel 
import System.Data.OleDb #para datagridview
import System.Data #para datagridview

from System.Windows.Forms import *
from System.Drawing import *
from Microsoft.Office.Interop import Excel 
from System.Runtime.InteropServices import Marshal 
from System.Data import * #para datagridview
from System.Data.OleDb import * #para datagridview

aux = [ ]

#ventana windows forms

-------self.label1.Text = 'LISTADO DE PROYECTOS:'
-------self.label1.Size = Size(300,30)

#boton para importar el excel
-------self.Button1 = Button()
-------self.Button1.Text = 'IMPORTAR'

-------self.Button1.Click += self.Button1Clicked


#los elementos que controla la ventana windows forms
-------self.Controls.Add(self.label1)
-------self.Controls.Add(self.DataGridView1)
-------self.Controls.Add(self.Button1)

        	
#funcion del Boton Importar
--def Button1Clicked(self, sender, args):
		#SELECCIONAR EL ARCHIVO .xlsx
-------openFileDialog = OpenFileDialog()
-------openFileDialog.Filter = "Excel |*.xls;*.xlsx;"
-------openFileDialog.Title = "Seleccionar Archivo"
		#ABRIR EXCEL EN BACKGROUND E IMPROTAR LA Hoja1       	
-------if openFileDialog.ShowDialog() == DialogResult.OK:
--------------filename = str(openFileDialog.FileName)
        	#cadena de conexion
--------------connectionString = 'Provider=Microsoft.ACE.OLEDB.12.0;Data Source=' + filename + ';Extended Properties="Excel 12.0 Xml;HDR=YES";'
--------------conn = OleDbConnection(connectionString)
--------------ds = DataSet()
--------------dt = DataTable()
        	#da = OleDbDataAdapter()
--------------ds.Tables.Add(dt)
--------------#consulta = "Select * from [Hoja1$]"
--------------#da = OleDb.OleDbDataAdapter(consulta,conn)
--------------da = OleDbDataAdapter(OleDbCommand("select * from [Hoja1$]", conn))
--------------da.Fill(ds)
--------------self.DataGridView1.DataSource = dt
--------------#aux.append(str(ds))


form = WindowForm()
Application.Run(form)
	
#OUT = aux

the problem arises when performing the fill method

There’s a DataTable node in the Data-Shapes package under the UI section that could display the excel

thanks! what I am trying to do with this script is to import directly from an excel, Data-Shapes is a very good tool, but I am avoiding the use of external nodes (so as not to have to download packages)
