Copy macros to other spreadsheets

Coding level: Intermediate
Duration: 30 minutes
Project type: Google Workspace Add-on

Objectives

• Understand what the solution does.
• Understand what the Apps Script services do within the solution.
• Set up the environment.
• Set up the script.
• Run the script.

About this solution

Manually copying Google Sheets macros from one spreadsheet to another can be time consuming and error-prone. This Google Workspace Add-on automatically copies a script project and attaches it to a user-specified spreadsheet. Though this solution focuses on Sheets macros, you can use it to copy and share any container-bound script.

How it works

The script copies the Apps Script project that's bound to the original spreadsheet and creates a duplicate Apps Script project bound to the user-specified spreadsheet.

Apps Script services

This solution uses the following services:

• URL Fetch service–Connects to the Apps Script API to copy the source project and create a copy.
• Script service–Authorizes the Apps Script API to avoid a second authorization prompt.
• Spreadsheet service–Opens the target spreadsheet to add the copied Apps Script project.
• Card service–Creates the user interface of the add-on.

Prerequisites

To use this sample, you need the following prerequisites:

• A Google Account (Google Workspace accounts might require administrator approval).

• A web browser with access to the internet.

• A Google Cloud project.

• The Google Apps Script API turned on in the Apps Script dashboard settings.

Set up your environment

Open your Cloud project in the Google Cloud console

If it's not open already, open the Cloud project that you intend to use for this sample:

1. Go to the Google Cloud console.
2. Next to Google Cloud, click the Down arrow . A dialog listing current projects appears.
3. Select your project and click Open. The console opens your project.

Turn on the Google Apps Script API

This quickstart uses the Google Apps Script API. Before using Google APIs, you need to turn them on in a Google Cloud project. You can turn on one or more APIs in a single Google Cloud project.

• In your Cloud project, turn on the Google Apps Script API.

  Turn on the API

Configure the OAuth consent screen

Google Workspace Add-ons require a consent screen configuration. Configuring your add-on's OAuth consent screen defines what Google displays to users.

1. In your Google Cloud project, go to Menu > APIs & Services > OAuth consent screen.

   Go to OAuth consent screen

2. Select the user type for your app, then click Create.
3. Complete the app registration form, then click Save and Continue.
4. For now, you can skip adding scopes and click Save and Continue. In the future, when you create an app for use outside of your Google Workspace organization, you must add and verify the authorization scopes that your app requires.
5. If you selected External for user type, add test users:
   1. Under Test users, click Add users.
   2. Enter your email address and any other authorized test users, then click Save and Continue.
6. Review your app registration summary. To make changes, click Edit. If the app registration looks OK, click Back to Dashboard.

Set up the script

Create the Apps Script project

1. Click the following button to open the Share a macro Apps Script project.
   Open the project
2. Click Overview .
3. On the overview page, click Make a copy .

Copy the Cloud project number

1. Go to your Cloud project in the Google Cloud console.
2. Click Settings and Utilities > Project settings.
3. Copy the Project number.

Set the Apps Script project's Cloud project

1. In your copied Apps Script project, click Project Settings .
2. Under Google Cloud Platform (GCP) Project, click Change project.
3. In GCP project number, paste the Google Cloud project number.
4. Click Set project.

Install a test deployment

1. In your copied Apps Script project, click Editor .
2. Open the UI.gs file and click Run. When prompted, authorize the script.
3. Click Deploy > Test deployments.
4. Click Install > Done.

Get the macro script and spreadsheet information

1. Open a Sheets spreadsheet that has a macro and that you have permission to edit. To use a sample spreadsheet, make a copy of the Sample macro spreadsheet.
2. Click Extensions > Apps Script.
3. In the Apps Script project, click Project settings .
4. Under the script ID, click Copy.
5. Set the script ID aside for use in a later step.
6. Open or create a new spreadsheet where you want to add the macro. You must have permission to edit the spreadsheet.
7. Copy the spreadsheet URL and set it aside for use in a later step.

Run the script

Make sure the Google Apps Script API is turned on in your dashboard settings. Take the steps in the following sections to run your script.

Copy the macro

1. In Sheets, on the right sidebar, open the Share Macro add-on .
2. Under Source macro, paste the script ID.
3. Under Target spreadsheet, paste the spreadsheet URL.
4. Click Share macro.
5. Click Authorize access and authorize the add-on.
6. Repeat steps 2-4.

Open the copied macro

1. If it's not open already, open the spreadsheet to which you copied the macro.
2. Click Extensions > Apps Script.
3. If you don't see the copied Apps Script project, make sure the Google Apps Script API is turned on in the dashboard settings and repeat the steps listed under Copy the macro.
