How to Stop Your Google Sheets Script from Repeatedly Executing Every Minute: A Simple Solution

Working with Google Sheets scripts can be a powerful way to automate tasks, but sometimes things don't go as planned. A common issue that many beginners encounter is running into triggers that execute repetitively, leaving you scratching your head as to why it's happening. If you’ve found yourself in this situation, you’re not alone!

The Problem: Unwanted Repeated Execution

Recently, someone faced a frustrating situation with their script. They wanted to send an email at a specific date and time using Google Sheets, but after the initial email was sent, the script continued to run every minute. This created unnecessary email traffic and confusion. Here’s the crux of the issue: their trigger was set up incorrectly, resulting in an infinite loop.

They needed a way to have the script run only once at the designated time.

Understanding the Initial Script

Let’s break down the original script to see what went wrong:

What Went Wrong?

Trigger Creation in the Same Function: Each time sendWAnow() is called, a new trigger is created that calls sendWAnow() again! This causes the function to execute repeatedly.

Infinite Loop: The script creates a recursive loop of creating triggers and executing the mail send function.

The Solution: Splitting the Functions

To solve this issue, you’ll want to create a dedicated function to set up the trigger and maintain the original function for sending emails. Here’s a simple step-by-step guide to implement this fix:

Step 1: Create a Trigger Function

First, create a new function to handle the trigger creation:

Step 2: Retain the Email Sending Function

Now, modify your email function to remove the trigger creation:

Summary

By separating the trigger setup from the email sending process, you can have your script execute just once as intended. Here’s a brief recap of what you did:

Created a dedicated function to handle trigger creation.

Modified the original function to solely focus on sending an email without setting additional triggers.

Using this organized structure will ensure your Google Sheets script runs smoothly and as expected, ensuring a hassle-free experience!

If you follow these steps, you’ll have control over when your email sends and eliminate any repetitive triggers. Happy scripting!
