AI Agent with Google Sheets Integration

Hi everyone,

I’m currently experimenting with callin.io’s AI Agent feature, and I’m facing an issue that I hope someone can help me with.

---

Goal:

I’m building a simple automation for learning purposes:

• A user sends a message via Twilio (e.g., “Create a Google Sheet called Meeting”).
• The AI Agent (using Groq as the model) receives the message and extracts the sheet name (“Meeting”).
• It should return a clean JSON object like this:

json
{
"action": "createSpreadsheet",
"title": "Meeting"
}


• This JSON should go into the Google Sheets tool node to create the spreadsheet.
• Finally, I send a confirmation back to the user via Twilio.

---

The Problem:

The AI Agent isn’t outputting usable JSON. It often wraps the content in markdown/code blocks or includes extra explanation text — which breaks the Google Sheets node input.

---

What I’m Asking:

• How can I make the AI Agent return clean, raw JSON only, without code blocks or extra text?
• Is there a good way to parse or clean the output if needed?
• Any advice on structuring prompts or flow logic so it works smoothly with the Google Sheets tool?

I’m currently using Groq (DeepSeek) as the model, but I also have access to Google Gemini (PaLM) API if switching models could help.

Thanks in advance!

Any guidance, examples, or best practices would be greatly appreciated.

Please provide the rewritten markdown content *it should be in the markdown format.
