This is a modified version of "https://gist.github.com/mciantyre/32ff2c2d5cd9515c1ee7". I modified it to add functionality to save the Name and description of the placemarks in the KML file along with the coordinates.

kmlToCSV.py

from bs4 import BeautifulSoup
import csv

def main():
    """
    Open the KML. Read the KML. Make 3 lists for Name, Coordinates and Description of the placemarks. Save the data to a CSV
    """
    name_counter = 0
    names_list = []
    coords_counter = 0
    coords_list = []
    desc_counter = 0
    desc_list = []
    
    with open('input_file.kml', 'r') as f:
        s = BeautifulSoup(f, 'xml')

        for names in s.find_all('name'):                #google earth nomenclature. Should read the KML file to see the relevant names we require
            names_list.append(names.string)
        names_list = names_list[2:]       #only keep names of placemarks
        name_counter = len(names_list)

        for coords in s.find_all('coordinates'):
            coords_list.append(coords.string)
            coords_list = [string.replace(',9','') for string in coords_list] #here i am manually removing the altitude from coords. Not the best way
        coords_counter = len(coords_list)

        for descriptions in s.find_all('description'):
            desc_list.append(descriptions.string)

    print(f'coords counter = {coords_counter}')
    print(f'descriptions counter = {desc_counter}')

    with open('output2.csv', 'w') as file:
        csv_writer = csv.writer(file)
        csv_writer.writerow(['Name', 'Coordinates', 'Description'])
        for counter in range(0, name_counter):
            csv_writer.writerow(
