Then I discovered Google Apps Script.

The first thing I automated wasn't particularly impressive. I had a Google Sheet containing rows of tasks, deadlines, and email addresses. Every morning, I was checking the sheet manually and sending reminders.

It worked.

It was also incredibly boring.

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

That tiny script changed how I looked at Google Sheets.

Apps Script is more powerful than it looks

Google Apps Script lets you work with services such as Sheets, Gmail, Drive, Calendar, and Docs using JavaScript.

For example, a simple script can read data from a spreadsheet:

function readTasks() {
  const sheet = SpreadsheetApp.getActiveSpreadsheet()
    .getSheetByName("Tasks");

  const data = sheet.getDataRange().getValues();

  console.log(data);
}

From there, you can start doing useful things:

• Send emails automatically

• Create Google Docs

• Move files in Drive

• Add calendar events

• Clean spreadsheet data

• Generate reports

• Build internal dashboards

• Create simple web applications

The interesting thing is that you don't need to build a backend server for many of these tasks.

Where things became difficult

Writing the first 20 lines wasn't the problem.

The problems started later.

Why didn't my trigger execute?

Why was getValues() returning something unexpected?

Why did my email function work manually but fail when triggered?

Why did my script suddenly hit a quota?

This is where Apps Script starts feeling less like spreadsheet automation and more like real software development.

And, honestly, this was the point where I started spending more time debugging than actually automating.

AI helped, but there was one annoying problem

Whenever I got stuck, my workflow was usually:

1. Copy the function.

2. Open an AI chatbot.

3. Paste the code.

4. Explain what I was trying to do.

5. Copy the suggested solution.

6. Return to Apps Script.

7. Test it.

8. Repeat.

The AI wasn't necessarily the problem.

The context switching was.

If the project had multiple files, I also had to figure out which code to copy into the AI tool.

Sometimes the issue wasn't even in the function I was looking at. It could be related to another file, a trigger, a variable, or the way the project was structured.

I started experimenting with AI inside Apps Script

At some point, I came across Google Apps Script Copilot, an AI coding assistant designed specifically for working with Apps Script projects.

What caught my attention wasn't simply the fact that it could generate code. There are plenty of AI tools that can do that.

I was more interested in the fact that it worked inside the Apps Script environment.

That meant I could ask questions about my project, work with the code I was already editing, and get help without constantly jumping between Apps Script and another browser tab.

For example, instead of copying a function into an AI chatbot and writing a long explanation, I could work with the project context and ask something more specific:

"Why isn't this trigger updating the status column?"

Or:

"Can you simplify this function without changing what it does?"

That felt much closer to having another developer looking over my shoulder than simply asking an AI to generate a random code snippet.

I've been using Google Apps Script Copilot mainly as a development aid rather than something I blindly let write everything for me.

That's an important distinction.

I still review the code.

I still run the script.

And I still want to understand what changed.

But removing the constant copy-paste cycle makes experimenting with Apps Script considerably less frustrating.

Start with one boring task

You don't need an elaborate automation project.

Find the task you repeat every week.

Maybe it's:

"Every Friday I create the same report."

Or:

"Every morning I check this spreadsheet and email people."

Or:

"Every time someone submits this form, I copy the data somewhere else."

That's usually a better starting point than trying to automate everything at once.

Write the smallest possible script.

Then improve it.

And if you get stuck, don't immediately assume you need a complicated development setup. Sometimes a small Apps Script and the right development assistance are enough.

That's how I went from thinking Apps Script was just a Google Sheets trick to using it as a small automation platform.
