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.
Google Apps Script is a JavaScript-based language that has access to Google Workspace-specific libraries for Gmail, Google Sheets, Google Forms, Google Drive, etc., and allows you to quickly and efficiently automate your tasks and program business applications.
A lot of users try and quickly learn GAS and use it to make their lives easier. It’s all great, however the code we sometimes tend to come across on StackOverflow and other sites lacks best practices, hence I thought it was time to start bringing them up and I will start today with design patterns.
I’m all for copy/paste coding and it one of the things I love about the Google Apps Script developer community, there are lots of great snippets out there and in Pulse we’ve now over 800 posts and counting. When you start going beyond quick script solutions into more complex projects investing time planning how you’ll structure your code can save you headaches and frustrations further down the line.
Using design patterns are one way to produce better code that is more readable which in turn is more maintainable and can lead to faster development. This post from Dmitry Kostyuk a nice opportunity to learn about a design pattern for a very common use case of maintaining data in a Google Sheet from a third party API.
Learn how the access the creator’s email of a Google Shared Drive with Google Apps Script using the Drive Activity API & Admin Directory SDK.
Scott Donald has found a clever way to get the Shared Drive creator using Apps Script and the Google Drive Activity API. Whilst there is a Google Drive ‘Drives’ endpoint the response doesn’t include the creator in the Drives Response object. This post is a nice example of how you can combine data from different Google Workspace APIs. Follow the source link for a detailed explanation.
This is a sample script for opening and closing Google Forms on time using Google Apps Script.
Here’s a handy little snippet if you would like to programmatically open/close one of your Google Forms to responses for specific hours of the day. The script includes another trigger that will repeat opening/closing the Google Form for responses each day. As this snippet uses .timeBased().at(date)Â it’s easy for you to modify if you want to only have the form open to responses between two specific dates/times.
Retrieving and saving properties in Google Apps Script can be slow, especially if there are a lot of them. SpeedStore is a blazingly fast in memory properties store which you can use to make retrieving and saving properties much easier.
Continuing yesterday’s theme highlighting some of the components for developing a Google Workspace Add-on where John McGowan highlighted how Properties Service can be used to store and use a “licence” property to customise your add-on UI, we continue by looking at how you can handle property storage.
There have been a number of community contributions in this area such as Bruce Mcpherson’s bmCrusher. Another option is SpeedStore from Joshua Snyder. Not as feature filled as bmCrusher but the benefit is the library is more compact. SpeedStore still comes with some very useful features including automatically handling properties over 9kb and JSON encoding/decoding. Perhaps the biggest benefit is speed particularly when you are using a single store for all your properties.
These are the sample scripts for hiding and deleting rows and columns on Google Spreadsheet [sic] using Google Apps Script. I sometimes see the questions for hiding and deleting rows and columns on Spreadsheet at Stackoverflow. So here, I would like to introduce the sample scripts for this.
In SpreadsheetApp there is the .deleteRow() and .deleteRows(), but when you have a lot of data or non-consecutive rows it can really eat into your Apps Script runtime limit. In searching for a better way of doing this I found this great solution from Kanshi Tanaike on Stack Overflow which uses the Google Sheets Advanced Service to delete multiple rows using one API call!
Using Sheets.Spreadsheets.batchUpdate isn’t just limited to deleting rows and for more examples see the source post which includes examples for hiding and deleting both rows and columns.
ChatGPT is pretty much a universal API: one endpoint to get any data.
ChatGPT has recently taken the world by storm. Unless you have been living under a rock, then you have certainly seen a variety of content on this topic. One of its greatest advantages is its ease of use, and it is perfectly usable in Google Apps Script. With that in mind, here is one use case that we can implement: generating fake data.
Fake data is useful for testing purposes. At times, real data is too sensitive, and sometimes you do not have access to real data before production, but you need to begin working with something. Here is where fake data comes in.
We used to have a great library for fake data called Faker.js; however, Marak, the author, became so frustrated that he could not monetize the solution that he pushed an update that broke everything, which led to him being blocked on GitHub and NPM. As a result, the library is no longer maintained. ChatGPT, however, is not going anywhere.
This is a sample script for merging multiple PDF files as a single PDF file using Google Apps Script. [and] This is a sample script for converting all pages in a PDF file to PNG images using Google Apps Script.
Kanshi Tanaike has recently been exploring and sharing some Apps Script solutions for handling PDF Documents using the PDF-LIB JavaScript library. So far they have looked at merging PDF files as well as converting PDF pages into PNG images.
The solution uses fetch and eval to load PDF-LIB, but with a minor modification hoisting the declaration of setTimeout you can also copy the source code into the script editor and avoid the evils of evals (a modified example here).
The Apps Script execution runtime limit will be a factor in the size of PDF Documents you can handle, but for smaller jobs a great solution to keep in mind.
