Downloading information to a file with heroku

There is a bot loaded on heroku, how can I register in it so that all the information is saved in an online table? If the bot is running locally, then everything is simple:

newlist=split(td_list,3) df = pd.DataFrame(newlist) df.to_csv("C:/orders.csv", encoding='utf-8',sep='\t') 

But what to do if the bot is running on a server ....
