If you use Drafts from Agile Tortoise, I invite you to check out my Coda Browser action for Drafts. Using the Coda API, the Drafts action allows you to retrieve data from your Coda docs — from doc, table, and column metadata to actual row contents — and also to send or upsert data to your Coda docs, using Drafts as an intermediary.
Please enjoy, kick the tires, and suggest any improvements. Thanks!
