Make ChatGPT build your spreadsheets for you! 

yeah, most of my open source started this way

yeah I'm impressed by how well GPT will stick to JSON when you instruct it to.

Pretty well! The biggest barrier was that the amount of context tokens needed for a large number of rows was far more than GPT-4 could handle. This week's announcements of GPT-4 Turbo, however, have me thinking this could work a lot better with the latest improvements (JSON mode, 160K context, etc)
