Google Sheets [🔧Fixed]. Prevent users from deleting formulas with Google Apps Script

You’ve made a formula, but someone deleted it. It may be annoying to restore your formula. You are not always able to protect a range with formulas, as protection will also forbid users from sorting range, adding new rows, hiding rows, etc.

Let’s create our formula protection with the help of a few formulas and app script code.

Google Sheets are fantastic for collaboration, the downside however can be that other people can break stuff. The Protected Sheets and Ranges can help with this, but there might be times when you need an alternative solution. If you find yourself in this situation Max Makhrov has come to the rescue with a solution to rewrite formula if they are accidentally deleted. You can find out more in the source post link. As a bonus Max includes a named Google Sheets function, FormulasMap, which can be used to export functions in a range to another sheet.

Apps Script Pattern. Stop Script Execution on conditions from a Google Sheet

The common pattern for checking the business logic before executing automation

Here’s a clever little snippet from Max Makhrov which combines Google Apps Script with conditional logic created using Google Sheets functions, the resulting cell value being used for the error message.

/**
 * @param {String} rangeName
 * 
 * @returns {Boolean} toStopExecution
 */
function getStopMessageBoxFromNamedRange_(rangeName) {
  var ss = SpreadsheetApp.getActive();
  var r = ss.getRangeByName(rangeName);
  var v = r.getValue();
  if (v === '') {
    return false;
  }
  var stopHeader = 'The script was stopped';
  Browser.msgBox(stopHeader, v, Browser.Buttons.OK);
  return true;
}

If after reading Max’s post you are unsure how this works, here is an example Google Sheet with some test data and logic as well as a ‘My Menu’ open to test the bound script.

5 steps to deploying Google Workspace Editors Add-ons to the Google Workspace Marketplace

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.

Custom function for get subtotals for each group in Google Sheets using Google Apps Script

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.

Sending emails with Amazon AWS Simple Email Service (SES) with Google Apps Script

This week was the first time I’ve tried AWS. I wanted to test AWS SES to write some emails with the help of Amazon. The learning curve was painful for me because I was totally lost in the documentation. Here’s what I came through

Max Makhrov is on a role with Google Apps Script and Google Sheets development. As well as this latest Medium post looking at Amazon AWS Simple Email Service (or as Max discovered – ‘Not so Simple Email Service’) if not already well worth following Max on Twitter (@max__makhrov) for lots of very useful Google Sheets/Script tips.

If you are hitting your quotas on Google Workspace daily email sends using AWS SES could be one solution. If you want to avoid the bold banners in recipients inboxes here’s some additional required reading on How to Set Up AWS SES and Avoid Spam Folders is essential reading. This covers setting up DNS records for SPF, DKIM, DMARC when using AWS SES. As these changes are required at a DNS level it’s not possible to set this up on regular @gmail.com accounts.

Using Google Apps Script to convert a Google Sheets selected range to an image 

Convert selected range into PNG image and save it to Drive

In this post from Max Makhrov you can discover how you can convert a selected Google Sheets range to an image. With options to embed charts and tables in Google Docs and Slides you might be asking why you would want to do this. Max highlights a couple of great reasons:

There are some limitations with this approach which are outlined in the post and if you have any solutions there is a link to contribute to the GitHub repo.

Dependent dropdown lists for Google Sheets (and lots of other Google Apps Script goodies)

Updated the script for dependent lists, and now it supports new options. New for 2022:

Dependent drop-down lists can be used to create a dynamic list of choices in Google Sheets. When the user makes a selection from the first drop-down list, the choices in the second drop-down list will be updated based on the selection. This can be used to create a cascading list of choices.

If you are looking for a nice solution to build dependent drop-down lists in Google Sheets this is a great solution from Max Makhrov. For more experienced Google Apps Script developers the solution incorporates some clever snippets both from Max and a number of other members of the community. Some highlights include: converting a column index into corresponding column letter; a tasker to batch apply updates to a Google Sheet; ChuckyCache for objects above 100Kb; and a reference to a zip compression solution. All these are referenced in the source code provided in the post.

JSONata – JSON query and transformation language in Google Apps Script

One of the benefits of Google moving Apps Script to the V8 engine is the possibility to drop in existing JavaScript libraries. Max Makhrov recently highlighted on Twitter how JSONata, which can be used to query and transform JSON data can be used in Google Apps Script:

JSONata is a lightweight query and transformation language for JSON data. Inspired by the ‘location path’ semantics of XPath 3.1, it allows sophisticated queries to be expressed in a compact and intuitive notation. A rich complement of built in operators and functions is provided for manipulating and combining extracted data, and the results of queries can be formatted into any JSON output structure using familiar JSON object and array syntax. Coupled with the facility to create user defined functions, advanced expressions can be built to tackle any JSON query and transformation task. – JSONata

JSONata is a solution better understood by trying it out, which you can do thanks to the script project shared by Max on Twitter or on the JSONata website. If you are interested in data query/manipulation solutions for Google Apps Script you might also want to check out our previous post on using AlaSQL for Apps Script.

Update: Max has published JSONata as an Apps Script library
