Forms can now be created, or have their draft questions replaced, by pasting a JSON document instead - available from "Create form" and from an "Import JSON" button in the form editor. A documented format (including question types and conditional follow-up questions) is built for pasting into an LLM alongside a description of the form you want, so a whole form can be generated and imported in one step.
Build a form by pasting JSON
Adding every question, choice, and follow-up rule to a complex form one at a time in the editor was the only way to build one.
