Automate Daily Google Calendar Events to Trello Cards

📋 Overview

This n8n workflow automatically converts your Google Calendar events for the current day into Trello cards every morning at 8 AM. It fetches all calendar events for the day, filters out routine events (like Lunch or Check email), and creates neatly formatted Trello cards with a predefined meeting notes template.

Perfect for professionals who want to keep their daily meetings and tasks synced with their Trello board.

⚙️ Key Features

• 🕗 Runs daily at 8 AM (configurable via Cron node)
• 📅 Fetches all Google Calendar events for the current day
• 🚫 Skips routine/repetitive events (Lunch, Check email, etc.)
• 🧩 Creates Trello cards with structured meeting notes
• 🔗 Includes event URL and due date in Trello card
• 🧠 Customizable filters and templates for full control

🧱 Workflow Steps

1. Run Daily at 8 AM (Cron Node)

Automatically triggers the workflow every morning at 8:00 AM. You can adjust the time as needed.

2. Calculate Today's Date Range (Function Node)

Generates the ISO-formatted start and end times for the current day (00:00–23:59). These values are passed to the Google Calendar node for querying events.

3. Fetch All Today's Calendar Events (Google Calendar Node)

Fetches all events scheduled for today using your Google account. The calendar email ([email protected]) should be replaced with your actual email.

4. Process Events One by One (SplitInBatches Node)

Splits the list of events into single items for individual processing.

5. Extract Event Details for Trello (Set Node)

Maps each event’s details (summary, description, start time, and URL) into structured fields ready for Trello card creation.

6. Filter Out Routine Events (If Node)

Skips over common recurring events (like “Check email,” “Lunch,” “Wrap Up & Clear Desk,” or “Beers and Griping”). You can customize this list as needed.

7. Create New Trello Card with Template (Trello Node)

For non-filtered events, creates a new Trello card using a predefined meeting notes template. Includes:

• Title: Event summary
• Due date: Event start time
• Description: Preformatted meeting notes layout
• Source URL: Event link from Google Calendar

8. Skip Filtered Event (NoOp Node)

Handles skipped events gracefully without performing any action.

🧰 Setup Instructions

1. Add Credentials

• Add Google Calendar OAuth2 credentials in n8n.
• Add Trello API credentials in n8n.

2. Replace Placeholder Values

• Update the calendar email in the Google Calendar node.
• Add your Trello board and list IDs in the Trello node.

3. Optional Customizations

• Modify the Cron node to change trigger time.
• Edit the Trello card template to match your meeting format.
• Add labels using idLabels in the Trello node.
• Adjust the filter conditions for different recurring tasks.

🧠 Example Use Case

Imagine you have daily meetings in your Google Calendar. Each morning, this workflow:

1. Collects all your events for the day.
2. Skips unimportant ones (like lunch breaks).
3. Automatically adds Trello cards for real meetings, each with a structured template for you to take notes and assign next steps.
