Google Sheets Retrieving All Data

Hi I am not sure if this is already been answered but is there a way to retrieve the all the contents of a google sheet and show it or do I have to create a for loop of sorts that just retrieves one line at a time? I am also very new to voice flow as appreciate all the help I can get. I know how to retrieve a specific line but I just want to see everything at once. Thank you

Do you have an example use case of what you would like your experience to do retrieving all data at once?

For example, I want to retrieve all the films on a list added by the user. I want to create a sort of watch list with many films the user has added to it and then when called upon it shows all the films in the list.
