Tired of manually managing your invoices in Gmail? Say goodbye to the hassle and hello to efficiency with Document AI and Apps Script.
There is a lot of buzz around generative AI, but it’s also worth remembering Google have a well established service offer in other forms of AI, the Document AI being one example of this. This post from Stéphane Giron highlight an Apps Script based workflow for analysing invoices attached to Gmail messages using the Document AI. There is a bit to setup in a Cloud project to get this working and as a paid for service costs to consider. Further information on this and all the code you need to get started are included in the source post.
This is a sample script for the folder picker using jsTree with Google Apps Script and Javascript.
The Google Picker is a file picker that allows users to select files from Google Drive which can be used in your Apps Script projects (See Using Google Picker with Google Apps Script). The Picker is good but there are certain scenarios where the functionality isn’t available, one I’ve personally found is selecting the My Drive or Shared drive root. Here’s an alternative approach from Kanshi Tanaike for an alternative folder picker created using jsTree. In the post you’ll find more information plus how you can use this solution with a service account.
In Google Workspace gam is probably the ‘go to’ tool command line tool which allows administrators to easily manage domain and user settings. Recently I was asked about how you can keep gam generated reports up-to-date using Google Apps Script. It’s worth remember that gam uses public Google Workspace APIs when it performs actions and reports. In this post I show you a pattern for building script to keep gam reports fresh.
AppSheet is headlined as a no-code platform but this doesn’t mean for developers there aren’t coding opportunities. In this post I’ll be sharing AppSheetApp, a Google Apps Script helper library we’ve made at CTS which makes it easy to use the AppSheet API in your own AppSheet apps. As part of this I’ll highlight how this library has made our AppSheet powered Grab n Go Chromebook loaner solution immediately scalable and data source agnostic.
In this post the worlds of AppSheet and Apps Script collide, the resulting fusion is a library which makes it easier to integrate external data and events into your AppSheet app. This solution hopefully makes it a lot easier for developers and low coders to do more with AppSheet creating the possibility to use one (or a couple) of lines of code to interact with your app and not worry which data source your app is using. This post has more details of how you can get started and an example of the impact its already making with an alternative Grab n Go Chromebook loaner solution I’ve been part of at CTS.
When I create some applications using Google Drive, there are often the case which is required to retrieve the file list and folder list. I had prepared the script each time for each case so far. But recently, I thought that if there is a library for retrieving the file and folder list (as a tree), it will be useful for me and other developers.
There’s a long standing issue with triggers installed programmatically by other triggers, that was kind of fixed last year, but users are still reporting problems, at least in certain locations (Japan, India and others). The issue in short: triggers installed programmatically would not be created, or fail systematically.
In many cases this affects add-ons (and, to be noted, the issue still persists when testing them, see Testing details); I had a slightly different scenario: a webapp that, when executed (doGet), would install a time based trigger for the user executing the script.
This article provides two solutions to an annoying issue and unlocks many possibilities for programmatically installed triggers.

Think 10x — supercharging your Google Apps Script solutions by directly calling Google Workspace Enterprise APIs.
The Google Apps Script built-in services like SpreadsheetApp, Maps and GmailApp are a great onramp for users with limited coding experience, the flip side is you can find yourself easily getting results but not in the most efficient way. DriveApp is a great example where Google have made it easy to iterate across folders and files, but when you have lots of folders and files it becomes a time consuming process and you hit execution limits.
An alternative approach is using Google Apps Script to make direct calls to the Drive API. The benefits of this approach is you can be more specific in the data you want back and it gives more flexibility with how you call the API, in some cases with the ability to make batch or asynchronous processes.
In this post I highlight a method ideal for scenarios when you want to index larger volumes of My Drive files and folders to a Google Sheet with calls directly to the Drive API. The post includes some sample code you can use which instead is able to reduce a 4 minute runtime to index 10,000 files and folders to one that can complete in under 40 seconds!
This is a sample script for putting the values of all Spreadsheets in a folder to the master Spreadsheet with a low process cost using Google Apps Script.
Some clever scripting from Kanshi Tanaike to combine individual Google Sheets in a Google Drive folder into a single master sheet. To achieve this the solution uses the Google Sheets Advanced Service combined with UrlFetchApp.fetchAll() to asynchronous process the source Google Sheets. It’s reported that this method was able to process 50 source sheets in 10 seconds!!! There are some limitations to be aware of highlighted in the source post, but for a method to quickly process a lot of data this solution is definitely one to keep in mind.
You get subtotal sums for each of the selected columns.
The code speaks for itself in this post from Max Makhrov in which he shows how to create a custom function for Google Sheets to subtotal groups of columns. There is some impressive data manipulation/reshaping going on in the function and some nice use of using arrays in formula created with brackets { }. Some of the code is also written with OpenAI/ChatGPT (I’m guessing anything with a for loop). The icing on top is the conditional formatting for group totals. Follow the source link for all the code.
An approach to process hundreds of thousands of rows of data (say, on Google Sheets) without running into the script execution timeout error.
TL;DR — the typical challenge we face with tasks that take longer to execute is that of running into the execution timeout error (that’s at 6 minutes — Script runtime — as of 10-Feb-2023) and this article … elaborates on how to bypass script execution timeout with a detailed example.
As noted in this post by Sourabh Choraria the Apps Script runtime limit can be a bit of a challenge. If you’re encounter problems my first tip would be review your script and see what you can optimize. A common problem I often see in Google Sheets is using .getValue()/.setValue() (singular) not .getValues()/.setValues() (plural).
If even with script optimization you are still having issues Sourabh provides a very adaptable ‘design pattern’ for Google Sheets. The pattern is one I can personally relate too and very similar to the approach I used in my own projects. The source post has everything you need to try this out for yourself.
