Step 1: Create a Google Sheet for Reminders 

  • Open Google Sheets and create a new spreadsheet. 
  • Add columns for reminder details, such as Date, Time, and Message. 

Step 2: Install Google Apps Script 

  • In the Google Sheet, go to Extensions > Apps Script. 
  • Write a script to check the sheet for reminder times and send messages to Slack. 

Step 3: Use Slack Webhook for Automation 

  • Set up a Slack Incoming Webhook by going to your Slack app settings. 
  • Use the webhook URL in your Google Apps Script to send the reminders automatically from your Google Sheet to the desired Slack channel. 

Now your reminders will be automated through Slack, keeping your tasks on track!
