🛠 What is the Debugger?
The Apps Script debugger lets you pause your code at any point and step through it line-by-line to see what’s really happening. You can inspect variables, monitor execution flow, and identify exactly where your script is misbehaving.

🧪 How to Use the Debugger
Open the script editor
Click on the bug icon 🐞 next to the function you want to debug
Optionally, add breakpoints (ctrl + b)
Press the Debug button
You can explore every variable, global or scoped, and inspect your data in real time.
Personally, I rely on the debugger while coding, especially when working on complex mapping algorithms. It’s a game-changer for understanding what’s happening under the hood.
Pro tip! If the function you want to debug relies on a trigger (like onEdit or onFormSubmit), you can build mock data to simulate the event and test your code manually.
