Product update: AI columns now speak JSON

Hey everyone!

Small quality-of-life improvement that a few of you asked for directly: you can now specify a JSON type in the output of AI columns.

This one came straight from Makers in the community who need AI columns to return JSON so they can manipulate it in later steps—filtering, mapping, feeding it into other automations, and so on. If that’s you, this makes AI columns a lot more dependable.

What it does

The new option does two things under the hood:

  • An explicit JSON output type. Selecting it tells the AI to reply in JSON and follow the instructions you’ve provided, rather than free-form text.
  • A built-in validity check. Once the column runs and generates a value, we check whether the response is valid JSON. If it isn’t, we automatically send a second prompt to correct the output—a simple way to improve adherence to the structure you requested.

Why it matters

Getting an LLM to reliably return well-formed JSON is usually the hard part. By making JSON a first-class output type and adding an automatic fix-up step, AI columns now give you structured data you can actually build on—no manual cleanup, no brittle workarounds.

Give it a try, and let us know what you’re using it for.

well done to @Henrique_Cruz1 and his team.

this is EXACTLY what i have been looking for.

i have spent the day testing this feature across all our coda ai agents, from the simplest to the most complicated.

my Agentix mechanism uses JSON objects as the ‘memory’ that coordinates all the agentic workflows.

so getting the coda ai to generate correct and precise JSON is vital to its effeciency.

prior to this i had to implement a range of special trickery to guarantee this, even repeating some prompts if the response was not proper JSON.

today i tested almost 1000 test cases on many different agent types, and the success rate was almost perfect.

(the few test cases that failed were due to badly formed prompts that need to be corrected.)

so this is a VERY SIGNIFICANT improvement to the superdocs ai capabilities.

We love us some @Henrique_Cruz1!

it is a most wonderful update and a serious building block in making Coda an AI first product. Love it.
