Add a correct format date in Excel file with Python openpyxl

Question

I need to add a new line from an excel file to a dict that has a date value, but this date value was entered in text format in the excel file's cell f.  This is my code to accomplish that; the datetime issue is present.

fromisoformat(row['Date']). strftime("%d/%m/%Y")

 however, it was put into the Excel file in text format.

Declaration_dict = Excel_Dict(r"\\path_to_excel_file.xlsx")
    for row in Declaration_dict:
        if row['statut'] == 'OK':
            line_declaration = (row['Cle_modifiee'], row['via'], row['Reference'], datetime.fromisoformat(row['Date']).strftime("%d/%m/%Y"), row['Detail'], row['NOM'], row['User'], row['Metier'], row['Equipe'], row['Libelle'])
            sheet_stock.append(line_declaration)

Answer 1

Use just datetime.fromisoformat(row['Date']) but I didn't have a cell with date format, the cell is with Standard format
