Students and working professionals use Google Docs every day to help enhance their productivity and collaboration. The ability to easily share a document and simultaneously edit it together are some of our users' favorite product features. However, many small businesses, corporations, and educational institutions often find themselves needing to automatically generate a wide variety of documents, ranging from form letters to customer invoices, legal paperwork, news feeds, data processing error logs, and internally-generated documents for the corporate CMS (content management system).
Mail merge is the process of taking a master template document along with a data source and "merging" them together. This process makes multiple copies of the master template file and customizes each copy with corresponding data of distinct records from the source. These copies can then be "mailed," whether by postal service or electronically. Using mail merge to produce these copies at volume without human labor has long been a killer app since word processors and databases were invented, and now, you can do it in the cloud with G Suite APIs!
While the Document Service in Google Apps Script has enabled the creation of Google Docs scripts and Docs Add-ons like GFormit (for Google Forms automation), use of Document Service requires developers to operate within the Apps Script ecosystem, possibly a non-starter for more custom development environments. Programmatic access to Google Docs via an HTTP-based REST API wasn't possible until the launch of the Google Docs API earlier this year. This release has now made building custom mail merge applications easier than ever!
Today's technical overview video walks developers through the concept and flow of mail merge operations using the Docs, Sheets, Drive, and Gmail APIs. Armed with this knowledge, developers can dig deeper and access a fully-working sample application (Python), or just skip it and go straight to its open source repo. We invite you to check out the Docs API documentation as well as the API overview page for more information including Quickstart samples in a variety of languages. We hope these resources enable you to develop your own custom mail merge solution in no time!

Google Apps Script makes it easy to create and publish add-ons for Google Sheets, Docs, and Forms. There are now hundreds of add-ons available and many are reaching hundreds of thousands of users. Google Analytics is one of the best tools to learn what keeps those users engaged and what should be improved to make an add-on more successful.
Add-ons run inside Google Sheets, Docs, and Forms where they can display content in dialogs or sidebars. These custom interfaces are served by the Apps Script HTML service, which offers client-side HTML, CSS, and JS with a few limitations.
Among those limitations, cookies aren’t persistent. The Google Analytics cookie will be recreated each time a user re-opens your dialog or sidebar, with a new client ID every time. So, Analytics will see each new session as if initiated by a new user, meaning the number of sessions and number of users should be very similar.
Fortunately, it’s possible to use localStorage to store the client ID — a better way to persist user information instead of cookies. After this change, your user metrics should be far more accurate.
Add-ons can also run via triggers, executing code at a recurring interval or when a user performs an action like opening a document or responding to a Google Form. In those cases, there’s no dialog or sidebar, so you should use the Google Analytics Measurement Protocol (see policies on the use of this service) to send user interaction data directly to Google Analytics servers via the UrlFetch service in Google Apps Script.
A Client ID is also required in that case, so I recommend using the Apps Script User properties service. Most examples on the web show how to generate a unique Client ID for every call to Analytics but this won’t give you an accurate user count.
You can also send the client ID generated on client side to the server so as to use the same client ID for both client and server calls to Analytics, but at this stage, it is best to rely on the optional User ID in Google Analytics. While the client ID represents a client / device, the User ID is unique to each user and can easily be used in add-ons as users are authenticated. You can generate a User ID on the server side, store it among the user properties, and reuse it for every call to Analytics (both on the client and the server side).
In add-ons, we usually rely on event tracking and not page views. It is possible to add different parameters on each event thanks to categories, actions, labels and value, but it’s also possible to add much more info by using custom dimensions & metrics.
For example, the Yet Another Mail Merge add-on is mostly used to send emails, and we have added many custom dimensions to better understand how it is used. For each new campaign (batch of emails sent), we record data linked to the user (e.g. free or paying customer, gmail.com or Google for Work / EDU user) and data linked to the campaign (e.g. email size, email tracking activated or not). You can then reuse those custom dimensions inside custom reports & dashboards.
Once you begin to leverage all that, you can get very insightful data. Until October 2015, Yet Another Mail Merge let you send up to 100 emails per day for free. But we’ve discovered with Analytics that most people sending more than 50 emails in one campaign were actually sending 100 emails - all the free quota they could get - but we failed to motivate them to switch to our paid plan.
As a result of this insight, we have reduced this free plan to 50 emails/day and at the same time introduced a referral program, letting users get more quota for free (they still don’t pay but they invite more users so it’s interesting for us). With this change, we have greatly improved our revenue and scaled user growth.
Or course, we also use Google Analytics to track the efficiency of our referral program.
To help you get started in giving you more insight into your add-ons, below are some relevant pages from our documentation on the tools described in this post. We hope this information will help your apps become more successful!:

Welcome to our 100th blog post on Apps Script! It’s amazing how far we’ve come from our first post back in 2010. We started out highlighting some of the simple ways that you could develop with the Apps platform. Today, we’re sharing tips and best practices for developing more complex Apps Script solutions by pointing out some community contributions.
The Apps Script editor does not allow you to use your own source code management tool, making it a challenge to collaborate with other developers. Managing development, test, and production versions of a project becomes very tedious. What if you could have the best of both worlds — the powerful integration with Google’s platform that Apps Script offers, along with the development tooling and best practices that you use every day? Now, you can.
npm install -g node-google-apps-script
This project, “node-google-apps-script”, is a Node.js based command-line interface (CLI) that uses Google Drive API to update Apps Script project from the command line. You can view the node package on the NPM site, and also view the GitHub repo. Both links have usage instructions. This tool was created by Dan Thareja, with additional features added by Matt Condon.
Before using the tool, take a look at the Apps Script Importing and Exporting Projects page. There are a few things that you should be aware of as you plan out your development process. There are also a few best practices that you can employ to take full advantage of developing in this approach.
There is a sample project that demonstrates some of the practices described in this post: click here to view that code on GitHub. To get all of the Apps Script samples, including this import/export development example:
Your standalone Apps Script projects live in Google Drive. If you use a command-line interface (CLI) tool like the one linked above, you can work in your favorite editor, and commit and sync code to your chosen repository. You can add tasks in your task runner to push code up to one or more Apps Script projects, conditionally including or excluding code for different environments, checking coding style, linting, minifying, etc. You can more easily create and push UI-related files to a file host outside of Apps Script, which could be useful if those same files are used in other apps you are building.
In addition to the information on the Importing and Exporting Projects page, here are a few things to consider:
Over and above the editing experience, the biggest improvements you get by working outside the script editor is that you are no longer locked into working in just one Apps Script project. You can much more easily collaborate as a team, with individual developers having their own working Apps Script projects, while also having more controlled test, user acceptance and production versions, each with more process and security. Beyond just the consistency with other normal project practices, there are a few Apps Script specific ways you can leverage this multi-environment approach.
If you are going to use this approach, here are three best practices to consider:
The provided sample shows a simple example of how a base configuration class could allow a developer to inject their local values for their own debugging and testing. In this case, the developer also added the annotation @NotOnlyCurrentDoc, which tells Apps Script that they need the full scope for Drive API access. In this project, the “production” deployment has the annotation @OnlyCurrentDoc, which leads to the OAuth scope that is limited to the document associated with script running as Sheets, Docs, or Forms add-on. If you add a standard file pattern to the source project’s “ignore” file, these developer-specific files will never get into the actual codebase.
Benefits for your project — Production can have more limited OAuth scopes, while a developer can use broader access during development. Developers can also have their own personal configuration settings to support their individual development efforts.
While there is no current way to trigger tests in an automated way, you still may want to author unit tests that validate specific functions within your projects. You’ll also likely have specific configuration values for testing. Once again, none of these files should make it into a production deployment. You can even use the Apps Script Execution API to drive those tests from a test runner!
Benefits for your project — You can author test functions, and keep them separate from the production Apps Script file. This slims down your production Apps Script project, and keeps the correct OAuth scopes that are needed for production users.
If you are developing an add-on for Sheets or Docs, and you expect to have an “active” item on the SpreadsheetApp. However when you are developing or testing, you may be running your Apps Script without an “active” context. If you need to develop in this mode, you can wrap the call to get the current active item in a method that also can determine what mode you are running in. This would allow your development or test instance to inject the ID of an “active” document to use for testing, while delegating to the getActive* result when running in a real context.
Benefits for your project — You can integrate better unit testing methodologies into your projects, even if the end deployment state dependents on resources that aren’t typically available when debugging.
You now have the option to use your own development and source management tools. While you still do need to use the Apps Script editor in your application’s lifecycle — to publish as a web app or add-on, configure advanced services, etc. — taking this step will help you get the most out of the power of the Apps Script platform. Remember to check out Apps Script on the Google Developers site to get more information and samples for your Apps Script development.
If you happen to use python tools on the command line to facilitate your team’s build process, you can check out Joe Stump's python-gas-cli. You can view the package info here or the GitHub repo where you’ll also find usage instructions.

Cross-posted with the Google Analytics Blog and the Google Apps Developer Blog
Many people have been asking for a simple way to put Google Analytics data into a Google Spreadsheet. Once the data is inside a Google Spreadsheet, users can easily manipulate Google Analytics data, create new visualizations, and build internal dashboards.
So today we released a new integration that dramatically reduces the work required to put Google Analytics data into any Apps Script supported product, such as Google Docs, Sites, or Spreadsheets.
Here’s an example of Google Analytics data accessed through Apps Script and displayed in a Google Spreadsheet.
We know that a popular use case of this integration will be to create dashboards that automatically update. To make this easy to do, we’ve added a script to the Spreadsheets script gallery that handles all this work - no code required. The script is called Google Analytics Report Automation (Magic).
This script is a great template for starting your own project, and we’ve had many internal Google teams save hours of time using this tool. Here’s a video demoing how to build a dashboard using this script:
You can find this script by opening or creating a Google Spreadsheet, clicking Tools -> Script Gallery and searching for “analytics magic”.
Of course many developers will want to write their own code. With the new Analytics – Apps Script integration, you can request the total visitors, visits, and pageviews over time and put this data into a spreadsheet with just the following code:
// Get Data. var results = Analytics.Data.Ga.get( tableId, startDate, endDate, 'ga:visitors,ga:visits,ga:pageviews', {‘dimensions’: ‘ga:date’}); // Output to spreadsheet. var sheet = SpreadsheetApp.getActiveSpreadsheet().insertSheet(); sheet.getRange(2, 1, results.getRows().length, headerNames.length) .setValues(results.getRows()); // Make Sandwich.
To get started now, read our Automated Access to Google Analytics Data in Google Spreadsheets tutorial. Also check out the Google Analytics Apps Script reference docs.
Are you ready to start building solutions using Google Analytics and Google Apps Script?
We’d love to hear new ways you use this integration to help manipulate, visualize and present data to solve business problems. To encourage you to try out this integration, we are giving out Google Analytics developer t-shirts to the first 15 developers to build a solution using both APIs.
To be eligible, you must publish your solution to either the Chrome Web Store or the Spreadsheets Script Gallery and include a description of a business problem the script solves. We’ll then collect these scripts and highlight the solutions in an upcoming blog post. After you publish your script, fill out this form to share what you’ve built.
We’re looking forward to seeing what you can do with this integration.
