Google Sheets to GameSalad Table Wire Format Gist
This gist has code you can import into your Google Sheet that will allow your google sheet to be an API that servers table data to your game. Because of the inherit limits of google docs, this should only be used for internal testing or for internal / personal apps that need to collect or read data. If you want to use this to manage live game data for bigger games, you should consider putting it behind a caching proxy that will reduce the number of hits directly to Google Docs.
