Google sheets, Integration, API, JSON

I’m currently making a playlist management app, I have 2 sheets within my google spreadsheet, one for playlists, and one for songs within the same playlists. I’m currently stuck on the Add_song (where I need to add a particular song to one of the columns of playlists, The user is meant to specify the playlist and the song tittle in his/her utterance before moving forward and adding it to the playlist)
I tried the create data with google sheets, but I want the column chosen to depend on the user’s utterance.
