Automated Task Reminders & Daily Recaps using Google Sheets and Slack

What This Workflow Does This workflow transforms Google Sheets into a lightweight productivity engine and connects it to Slack for automated reminders and daily recaps. No extra SaaS, no extra cost – just a simple system that keeps you on track and accountable.

Pre-conditions / Requirements Before you start, make sure you have: A Google account with access to Google Sheets. A Slack workspace where you can post reminders and summaries. An n8n instance (self-hosted or cloud) with: Google Sheets credentials connected. Slack credentials connected.

How It Works Task Tracking in Google Sheets Add tasks with columns: Task ID, Task Name, Due Date, Status, and Why it matters. The workflow checks for tasks that are due soon or overdue.

Automated Slack Reminders Every 15 minutes, the workflow scans for tasks due in the next 30 minutes. Slack sends a ping with the task name, deadline, and reason.

Daily Recap at 6 PM Slack posts a summary of how many tasks you completed vs how many are still pending. Encourages reflection and accountability.

Duplicate Protection Each task has a "Last Reminder Sent" column so you don’t get spammed with repeat messages.

Customization Options Reminder Frequency**: Change the Cron node to check tasks every 5, 10, 30 minutes, or hourly.
Daily Recap Time**: Adjust the daily Cron node (default: 6 PM) to match your schedule.
Slack Channel**: Point reminders and recaps to a private DM, a public channel, or multiple channels.
Task Fields**: Add columns like Priority, Assigned To, or Category and adjust Slack messages accordingly.
Weekly Review**: Extend the workflow with another Cron node on Sundays to send a weekly productivity score.
Reflection Logs**: Add automation to write daily results into a second tab for trend tracking.
