When you are developing Google Apps Scripts, you might get an exception that says: “Exceeded maximum execution time”. This indicates that the code which is running your script has exceeded the 30-second execution time limit. The maximum execution time of 30 seconds can be increased using the setTimeout() function. In this article, I’ll explain what causes these errors and how to fix them.
Exceeded maximum execution time Exception in Google Apps Script
Exceeded maximum execution time Exception in Google Apps Script
The maximum execution time for a script is set by default at 20 seconds. You can check the current value of your script’s maximum execution time by viewing its properties in the Script Editor window. If you’re using a pre-existing template or add-on that was created before June 2019 and has not been updated since then, this may be why it’s not working properly. If so, contact us so we can help update it for you!
If there are any steps that take more than 5 seconds to complete (such as opening a web page), try breaking them up into smaller chunks with sleep() statements inserted between each one–or consider redesigning your workflow altogether if possible!

Why am I getting this Exception?
The maximum execution time for a script is 30 seconds. If your script takes longer than this to execute, you will get an exception.
The amount of time it takes for your script to execute depends on what it’s doing and how much data it needs access to. For example:
- If you’re running some calculations on a large dataset in Google Sheets (such as pulling data from multiple sheets), then this can take more than 30 seconds because there are many rows and columns being processed at once.
- If you’re calling another service like BigQuery or Cloud Storage, those services may also have their own limits that affect how long they take before returning results back to Apps Scripts running on them (see below).
What can I do about it?
If you’re getting this error, you can try increasing the execution time limit for your script. You can do this by going to the Script Execution Time Limit section and changing the value of Maximum Execution Time (seconds).
This will help prevent your code from exceeding this limit, but if you need to run longer scripts or processes, then there are other options available as well.
You can use one of several tools within Google Apps Script:
- Script Debugger – an integrated development environment (IDE) that allows users to debug JavaScript code while it executes in their browser window or desktop Chrome app. It also includes some useful features like syntax highlighting and breakpoints so that users can step through their code line-by-line as it runs on the web page where they’ve opened up their editor window;
- Profiler – a tool designed specifically for profiling large amounts of data within applications built using GAS;
- Stack Trace – provides information about errors raised during runtime execution like type name/value pairs for each exception object created during script execution along with related objects such as function calls which may have caused them (if applicable);
- Debugger Logging – logs all exceptions raised during runtime execution along with related objects such as function calls which may have caused them (if applicable).
The Exceeded maximum execution time Exception in Google Apps Script is a common problem for developers. It can be difficult to diagnose and resolve, but it’s important to understand why you are getting this exception so that you can take steps toward fixing it.
We have created code in this article that will help solve this problem by setting up a timer that will automatically pause itself when it reaches a certain limit. This way, if any of your scripts take too long to run, they won’t cause other processes on your site or app (like sending emails) from timing out as well!
If you’re working with a JavaScript codebase and the app is taking too long to execute, you might want to restrict the maximum execution time. This can be done by setting a value in your script’s configuration settings:
- [Google Apps Script][1] > Scripts > [YourScript] > Settings
In addition to restricting the maximum execution time, it may also be helpful to use the debugger or profiler (or both) when debugging your codebase.
