hack'n around

You can use the save log button to get a csv file of the data, this only works with chrome and some versions of chromium.

The following converts the csv file to a sqlite3 database file name 'data.db', with a table named 'can' containing all the records.

import sqlite3
import pandas
conn = sqlite3.connect('data.db')
df = pandas.read_csv('data.csv')
df.to_sql('can', conn, if_exists='append', index=False)
