Hey @btsang
Sorry for the delay getting back to you, this one slipped through.
This is very possible with the Tables API. Here is a good document that will get you started using the tables api:
My preferred language to do basic software work like this is Python. Here is some example code that encodes images to text, then uploads them to a table.
If this is your first time playing with the api, or python, this would be a great topic to cover in a future office hours session:

Meet - New User Office Hours
Thursday 11AM EST - Meet - General Office Hours
Thursday 4PM EST - Meet - New User Office Hours
Hope this helps!
