I have three excel spreadsheets that i need to use in jupyter notebook but i don’t know how to use access them, i tried importing them to the folder but when opened they had no data in them at all, they’re currently local files on my laptop (windows). i don’t know if they can be accessed locally or how to correctly upload them, i’m also using jupyter notebook online if that makes a difference. i could really use some help as this assignment is due tomorrow. sorry if question isn’t coherent its already been a very long day and i’m only getting this started at 10pm.
