Move files uploaded with Google Forms to specific folders in Google Drive with Google Apps Script

Learn how to move uploaded files from Google Forms to a specific folder in Google Drive. You can also rename the files based on the form responses

Amit Agarwal, the brains behind Digital Inspiration’s Document Studio must have one of the most feature full Google Workspace Marketplace Add-ons. I also like Amit’s approach of sharing how you can solve problems like moving Google Form file uploads using Document Studio as well as providing an Apps Script snippet if you would like to manually code it.

In this example some setup is required to specify a folder ID and create an onFormSubmit trigger. After this the script then retrieves uploaded files from the form response, creates a subfolder named after the unique Response ID, and moves the files into that subfolder within the specified parent folder. This provides a structured and organized way to manage file uploads from Google Forms.

Allowing access for IMPORTHTML, IMPORTDATA, IMPORTFEED, IMPORTXML, and IMPORTRANGE on behalf of the user in Google Sheets

Image credit: Kanshi Tanaike

In February 2024, Google made a change in Google Sheets to enhance data security. Now, users must provide explicit consent before Sheets can connect to external data sources. This change aims to prevent unintentional data leaks and improve overall data loss prevention within Google Sheets.

Impact on Users:

When manually adding or editing certain IMPORT functions (IMPORTHTML, IMPORTXML, IMPORTFEED, IMPORTDATA) and the IMAGE function in a Google Sheet, a warning banner will appear blocking sending a receiving data until the user gives consent. To enable this functionality, users need to click “Allow access.”

Impact on Developers:

As highlighted in the first source post by Justin Poehnelt, this change caused issues for developers who programmatically create Google Sheets and automate tasks, such as generating PDF documents  as the IMPORT and IMAGE functions were blocked.

Solutions for Developers:

Fortunately, Google introduced an update to the Google Sheets API to address this challenge. Developers can now enable external data access programmatically by setting the importFunctionsExternalUrlAccessAllowed property in the Google Sheet metadata. This allows specific IMPORT and IMAGE functions to work without manual user consent.

For the IMPORTRANGE function, a similar API property is currently unavailable. However, an unofficial workaround exists that involves calling an undocumented endpoint using Google Apps Script as detailed in the second source post by Kanshi Tanaike.

Future Expectations:

As Google continues to prioritize data security, there will likely be further enhancements to data loss prevention controls within Google Workspace. Hopefully, future updates will also include official API controls for IMPORTRANGE and other functions to facilitate legitimate data access for developers while maintaining data security.

Google Apps Script gets a public knowledge base of Github projects with Gassypedia

All the Google Apps Script related github activity is now on Google Bigquery and Google Looker. Here’s how it was done.

Bruce Mcpherson has recently revisited his work on the visual Google Apps Script explorer tool, scrviz. Bruce has been working diligently to address limitations with the Github API and overcome quota restrictions. This new iteration still allows users to explore Google Apps Script projects and creators, but this time through a shared Looker Studio dashboard. The underlying dataset has also been made available on BigQuery if you would like to do your own analysis.

How to access secrets from Google Secret Manager using Google Apps Script

This detailed guide explains how you access your passwords, API keys and other sensitive data stored in the Google Secret Manager with Google Apps Script.

API keys and other credentials are your digital passports to access valuable data and services from various online platforms. When you’re developing Google Apps Script projects that connect to using keys, it’s of paramount importance to handle these keys with care and prevent them from falling into the wrong hands. Mishandled API keys can lead to unauthorized access, data breaches, and potentially even financial consequences.

One way to store API keys in Google Apps Script is the built-in Properties Service. This service offers a mechanism to store key-value pairs attached to your Apps Script project. While the Properties Service offers a convenient way to store sensitive data, it comes with limitations:

  • Not True Encryption: The Properties Service stores data in a readable format. Anyone with sufficient access to your Apps Script project might be able to view the API keys.
  • Limited Access Control: It’s challenging to implement fine-grained access restrictions over who can see the stored keys within the Properties Service.

For a more secure and scalable approach you might consider using Google Cloud’s Secret Manager. As described by Amit Agarwal in this source post:

Google Secret Manager is a cloud service where you can store sensitive data such as passwords, database credentials, encryption keys or any other confidential information that you don’t want to hardcode in your application’s source code. You can also set up an expiration time for the secret and the Google Secret Manager will automatically delete the secret after the specified time.

You can read more about using the Google Cloud Secret Manager in Amit post, which also includes the setup and Apps Script code snippets to make it work. For some general best practices on key management, Google provide this support article.

Find out who has access to your Google Drive files using Google Apps Script

In this blog we are going to find out who exactly has access to my Google Drive files, be it a Google Sheet, Google Doc, Form and more. To do this we are going to be using the DriveApp and Google Apps Script.

Recently Aryan Irani shared this post which shows how you can get the file permissions on a Google Drive file using DriveApp. This uses the DriveApp methods for .getEditors() and .getViewers(), which left me wondering about commenters???

The answer is file commenters are included in the .getViewers() response and as pointed out by TheMaster you can filter out commenters with .getAccess().

Another approach is to use the Advanced Drive Service:

The advanced Drive service lets you use the Google Drive API in Apps Script. Much like Apps Script’s built-in Drive service, this API allows scripts to create, find, and modify files and folders in Google Drive. In most cases, the built-in service is easier to use, but this advanced service provides a few extra features, including access to custom file properties as well as revisions for files and folders.

Learning about the Advanced Drive Service can be useful as it open up more opportunities to interact with Google Drive content and can also help you get file properties.

In the case of permissions there is a dedicated Permissions Resource that allows access to all the file permissions. For example, if I wanted to see what accounts had access to a file in MyDrive you can use:

// Requires Drive Advanced Service v3
const fileP = Drive.Permissions.list(fileId, {
  fields: "*" // all fields
});

fileP.permissions.map(perm => {
  console.log(`${perm.role} - ${perm.emailAddress}`)
});

Using the Advanced Drive Service does require a step up in understanding how to call the Drive API and the response you get but once you begin understanding it can come with huge benefits with more efficient code.

Creating dining reservation system with Google Apps Script

Google Apps Script automates tasks (even offline) and builds web apps using spreadsheets as databases. This report presents a basic dining reservation system to illustrate key aspects of web app development with Apps Script, HTML, and Javascript.

One of my first Google Apps Script projects was an event booking system. It was a great way to learn about integrating with the various services like Google Calendar. Roll forward 14 years and it is a topic that Kanshi Tanaike has revisited with a dining reservation system built on Google Sheets with a web app frontend.

All the code is published on GitHub and even if you don’t need a reservation system a great opportunity to see how one can be coded and there could be lots of juicy little snippets that you can use in your own projects.

How to audit Google Shared Drive permissions in Google Sheets with Apps Script

Are you looking for an efficient way to get an overview of all shared drives and their access permissions within your organization? Whether you’re navigating a company reorganization or implementing security procedures, accessing this information can be challenging.

This post from Niek Waarbroek highlights the important of auditing Google Shared Drive permissions. This can be a challenge to do using the Google Workspace Admin Console, especially if you have lots of Shared Drives.

To help Niek has shared a Google Sheet with Apps Script code that automatically generates a list of all shared drives and their associated root level permissions.

Shared Drive auditing is bit of a niche subject, but I encourage you to have a look at the post and script as it has some nice features which could be applicable to other projects. For example, there is a gaspTimeManager to make sure the script doesn’t go beyond the script execution limit.

🔒Preventing Cross-Site Request Forgery (CSRF) in Google Apps Script Dialogs and Sidebars 

 

If you are looking to publish a Google Workspace Editor Add-on, you may need to consider upping your security with an anti-CSRF token.

Scott Donald has shared some really useful information about protecting your Google Workspace and Apps Script data from malicious websites using anti-CSRF tokens. Google is currently in the process of reviewing Google Workspace Add-ons which means for many restricted scopes in Google Drive developers need to complete CASA Tier 2 security assessments, which require anti-CSRF token.

For more context CSRF attacks are a type of cyberattack that can allow hackers to trick your browser into sending unwanted requests from your account, such as making purchases or changing your settings. This can put your data and privacy at risk.

Anti-CSRF tokens are a simple but effective way to prevent these attacks. They work by generating a unique ID for each user session, which is then included in all requests sent to Google Workspace and Apps Script. This way, the server can verify that the request is legitimate before processing it.

Implementing anti-CSRF protection is relatively easy and this tutorial from Scott explains have you can implement it in your Google Workspace Editor Add-on.

Managing Google Cloud Storage files with Google Apps Script without using a service account

Using Google Apps Script scoped authentication to interact with Google Cloud resources without a service account

A key feature of Google Apps Script is its integration into Google Cloud. The default behaviour when any Apps Script project is created is that an associated Google Cloud project is created and configured. This default project is not accessible to the user and for most scripts, the user doesn’t need to worry about any of the configurations such as enabling APIs and configuring authentication settings.

Other key aspects are identity and authentication. The default behaviour for scripts is usually to run as the account executing the script, Apps Script automatically determining what authorisation is required for different Google services based on an automatic scan of your code or from what scopes have been set explicitly in the Apps Script manifest file.

The last piece in the puzzle is the .getOAuthToken() method which is part of the ScriptApp Service:

Gets the OAuth 2.0 access token for the effective user. … The token returned by this method only includes scopes that the script currently needs. Scopes that were previously authorized but are no longer used by the script are not included in the returned token. If additional OAuth scopes are needed beyond what the script itself requires, they can be specified in the script’s manifest file.

What this means is in script projects we can borrow an access token to use other services that the effective user has access to and have been declared in the script project scopes. For example, if my Google account [email protected] has been added to another Google Cloud project with the Google Cloud Storage service enabled, I can use Apps Script to generate a token to use the Cloud Storage service in that project.

To help illustrate this, here are two examples for interacting with Google Cloud Storage buckets to upload and download files to Google Drive.
