Gmail will not render base64 images embedded inside HTML emails but with Google Apps Script, you can use blobs to send the base64 encoded images
Base64 is a way of encoding binary data (like images) as a string of text. This makes it possible to embed images in webpages and HTML emails without hosting images on a server. An issue however, particularly for email, is that not all email services like Gmail support base64 encoded images.
Amit Agarwal’s latest blog post discusses a workaround for Gmail which involves using Google Apps Script to convert the base64 images to a blob and then embedding the blob in the email. There are some nice techniques in this post for handling/searching text strings with regular expressions as well as converting them to a Gmail friendly format.
Learn how to conduct a pirate raid in Google Chat Spaces with Webhooks and Google Apps Script. Video Included.
Google continue to add and enhance Google Chat. The fun doesn’t stop at the end user experience, Google also adding functionality to the Google Chat API. A low-lying entry point for Google Workspace developers is using Google Chat webhooks. As a HTTP endpoint you can use your coding language of choice.
In this tutorial from Scott Donald you can learn how Google Apps Script can be used to interface Google Chat using webhooks. The post includes everything you need to get started including a tutorial video. There are some nice tips including how to post replies to a chat thread and formatting responses using the card service. Follow the link to start learning more…
This video shows how to use the Palm API with Google Apps Script to extract data from Google Analytics 4 accounts. This can be useful for a variety of purposes, such as creating custom reports, automating data analysis, and building new data-driven applications.
Following on from the last post in Pulse where we looked at using Google PaLM API and MakerSuite in Google Apps Script, here’s another example from GDE Linda Lawton. As the video in the post shows Linda has been able to engineer prompts that allow you to use natural language to extract reports from Google Analytics. This shows the emergent capabilities of LLMs as well as some clever prompt engineering. The source post contains more detail, but here is an example:
var text = "The current date is '"+ date + "'. Create a JSON object which contains five parameter's dimension, metrics, start_date, end_date and property_id. The dimension and metric parameter's will be comma separated strings they can be empty if there is no valid text for it. The value of the dimension parameter should be a comma separated string of these dimensions names 'country, eventName, city, audienceName' and the value of the metric parameter should be a comma separated string of these metric names 'activeUsers, eventCount, screenPageViews', the property_id field will also be a string it will be a large number, start date and end date must be in the following format YYYY-MM-DD, which can be found in the given this text '" + prompt + "'. If no start date is found use set it to seven days ago and if no end date is found set it to today."
A couple of highlights worth noting:
Context – The current date is included programmatically to give the LLM a reference point
Reinforcement – ‘start date and end date must be in the following format YYYY-MM-DD’
Exceptions – ‘If no start date is found use set it to seven days ago and if no end date is found set it to today’
This post has covered how you can quickly copy MakerSuite code examples to run them in Google Apps Script. To make the iterative process easier I’ve created GenerativeLanguageApp so that once you’ve created/saved an API key, you can drop these code snippets into your Google Apps Script project:
Generative AI (GenAI) is a rapidly developing field that has the potential to revolutionize many industries, including the way we work. Google has developed a number of LLMs that are generally available to developers, including foundation models trained for text, chat and code which are accessible as part of the PaLM 2 API. To help developers explore the capabilities of these models, Google has created the MakerSuite site.
In this post I share GenerativeLanguageApp, a Google Apps Script helper class which makes it easy to quickly copy MakerSuite code examples to run them in Google Apps Script. This is a great way to start experimenting with LLMs and seeing how they can be used in Google Workspace.
In the next part of this series, I’ll explore some of the capabilities of when using the PaLM 2 API with data from Google Sheets. Stay tuned!
In this report, I would like to introduce a sample script for efficiently deleting rows by conditions on Google Spreadsheet using Google Apps Script. Recently, I had a situation for being required to achieve this situation. In my report, it has already known that when Sheets API is used, the rows can be efficiently deleted by a condition. Ref However, in that case, Sheets API couldn’t be used. Under this situation, I came up with a method. In this report, I would like to introduce this method.
Here’s a clever method from Kanshi Tanaike for deleting rows in Google Sheets based on a column condition. The solution makes use of the built-in .removeDuplicates() method, the clever bit is the script first copies the header row into any row that matches the condition. As this creates duplicate rows the .removeDuplicates() method can be called to the entire data range. Using this method Kanshi was able to improve an execute of an earlier function from 67 seconds to 13 seconds!
I recently faced a frustrating issue when writing data to a CloudSQL database with the JDBC class in Apps Script. I kept getting the following error:
Exception: Argument too large: SQL
I also observed that it only happened when my SQL query reached a certain length. I considered breaking it down into multiple queries, but I was still puzzled 🤔 because I was only sending a few dozen kilobytes of data.
Now, the thing is, the official documentation could be more helpful; even though the solution is there, it needs to be better explained. So, I turned to StackOverflow. There was a discussion on this exact topic, but to my surprise, I was still waiting for an answer. Until, well, I wrote it 😉
This guide is not documentation, but a condensed reminder of what you must do.
Max Makhrov has put together this very succinct guide to publishing Google Workspace Editor Add-ons to the Google Workspace Marketplace. As explained by Max the guide isn’t a step-by-step tutorial, but instead provides the key steps you should remember to do. There are some great tips in this post, particularly around what to include in the recorded screencast required by the Google oAuth verification team.
Learn how extract all the embedded images from a Google Document or Google Slides presentation and save them as individual files in a specified folder in your Google Drive.
Often I’ll use Google Docs for drafting blog posts. With the introduction of Duet AI having a generative assistant in situ helps with the creative process. As well as text Google Docs is a really simple canvas for quickly copy/pasting screenshots. Copying content from Google Docs to WYSIWYG editors can sometimes be challenging, particularly, when it comes to images.
Next time I encounter this problem I’ll be using the script solution from Amit Agarwal, which can extract images from Google Docs and Slides and save them to Google Drive. I’m sure there are many other situations where this snippet could come in handy.
Unfortunately, there are no built-in methods for directly managing PDF data using Google Apps Script. Fortunately, after the V8 runtime has been released, several raw Javascript libraries could be used with Google Apps Script. pdf-lib is also one of them. When this is used, PDF data can be cooked over Google Apps Script. In this report, I would like to introduce achieving this using a Google Apps Script library.
Google Apps Script is a powerful tool for automating tasks. It can be used to process data, create spreadsheets, and send emails. One of the limitations of Apps Script is that it does not have built-in support for PDF files. However, there are a number of third-party libraries that can be used to work with PDF files and in Pulse we’ve featured a number of posts from Kanshi Tanaike where they have explored the pdf-lib is a JavaScript library.
This work has culminated in PDFApp, a dedicated Apps Script library created by Kanshi Tanaike based on the pdf-lib, but optimised for Apps Script. The source post includes a number of recipes for handling PDF files listed below:
Are you looking for a way to receive notifications in real-time when an important spreadsheet in your Google Drive get modified or is accidently deleted by sometimes? Well, Google Drive offers an API to help you set up a watch on any file in your Google Drive be it a document, presentation or even a PDF file. This means that you can receive instant notifications whenever the content or even permissions of that file changes.
This tutorial explains how you can setup watch notifications on any file in your Google Drive with the help of Google Apps Script.
As part of the Google Drive API you can set up watch notifications on any file in your Google Drive. This means you can receive instant notifications whenever the content or permissions of that file changes. This feature can be useful for a number of scenarios, for example, if you have sensitive Drive files that you want to closely monitor, or a workflow where you’d like to trigger additional events when a file is updated.
This post from Amit Agarwal explains how you can create a push notification for a Google Drive file using Google Apps Script. As noted in the post you can use Google Apps Script to handle the push notification by creating a doPost Web App, however, not all the response data/headers are available using Google Apps Script. There is a related ticket which had some activity earlier in the year and I would encourage you to star the request to get updates and encourage Google to fix – https://issuetracker.google.com/issues/67764685.
Google Workspace Admins looking for domain/user activity on Drive files might want to look at the Reports API activities endpoint, which can be configured to setup similar watch notifications. You can read more in the Reports API: Drive Activity Report overview.
