I Used Google Apps Script to Automate My Most Boring Spreadsheet Tasks

Description and use

Automating daily task checks and email reminders in Google Sheets using a lightweight Apps Script, eliminating manual effort.

Problem

Manually checking a Google Sheet each morning and sending email reminders for overdue tasks was tedious and error‑prone.

Outcome

The script reduced manual effort, ensured timely reminders, and demonstrated that Apps Script can serve as a lightweight automation platform without a separate backend.

Workflow

• 1. Open Google Apps Script editor linked to the spreadsheet.
• 2. Write a function (e.g., readTasks) that gets the active sheet and reads data with getDataRange().getValues().
• 3. Add logic to filter rows where the deadline is past and status is incomplete.
• 4. Use GmailApp.sendEmail() to send reminder emails to the addresses in the filtered rows.
• 5. Set up a time‑driven trigger (e.g., daily at 8 AM) to run the function automatically.
• 6. Test the script manually to ensure emails are sent correctly.
• 7. Deploy and monitor for quota limits or errors.

Evidence

I wrote a small Apps Script that read the spreadsheet, looked for overdue tasks, and sent an email reminder.
