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

1. 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.

2. 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.

3. 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.

4. 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.

Benefits

• ✅ Eliminate missed deadlines with proactive reminders.
• ✅ Daily accountability inside Slack – no extra dashboards.
• ✅ Zero SaaS costs – only Sheets, Slack, and n8n.
• ✅ Fully customizable to match your workflow, team, or habits.
• ✅ Scales easily from solo use to team task tracking.

Use Cases
