Module 5: Deploying and Sharing Custom Functions

Key Takeaways:

– Properly document your custom functions for easy understanding and usage

– Maintain version control and update custom functions as needed

– Share your custom functions with others and distribute them as add-ons

Introduction: Sharing Your Custom Solutions with the World

After creating highly functional and tailored custom functions, your next step is to optimize, secure, and share them with other Google Sheets users. In this module, we will explore best practices for documenting custom functions, managing updates, and distributing them as add-ons.

5.1 Best Practices for Documenting Custom Functions

Proper documentation is crucial for understanding, maintaining, and using custom functions. Well-documented code helps both the creator and other users to comprehend the function’s purpose, syntax, and usage. Some best practices to follow include:

– Begin with a clear and concise description of the function’s purpose

– Provide a detailed explanation of each input parameter and its data type

– Include examples demonstrating the correct usage of the function

– Describe any output values or possible error messages

– Use comments within the code to explain the logic and working of the function

5.2 Version Control and Updating Custom Functions

Version control is essential for tracking changes and modifications to your custom functions over time. Google Apps Script provides version control and updates management through the “File” menu. Here’s how to manage versions and updates:

1. In Google Apps Script, click “File” and then “Manage versions.”

2. Enter a description for the new version, and click “Save New Version.”

3. Keep a detailed changelog that documents any modifications made to the custom functions.

To update a function, use the version history to roll back to a specific version or make any necessary changes and save it as a new version.

5.3 Sharing Custom Functions with Other Users

Sharing custom functions with others is as simple as sharing a regular Google Sheet. However, ensure that they have the required permissions to access the script and use the custom functions. The following steps explain how to share your custom functions:

1. In the script editor or Google Apps Script, click “Share.”

2. Enter the email addresses of the collaborators or share the link with the desired access level (edit, comment, or view).

3. If required, provide additional instructions or documentation for the proper usage of the custom functions.

5.4 Exporting and Importing Custom Functions as Add-ons

Distributing custom functions as add-ons allows users to easily import and utilize them in their Google Sheets. To create an add-on:

1. In Google Apps Script, click “Publish” and select “Deploy as Sheets add-on.”

2. Complete the required information like project name, version, and description.

3. Choose the deployment type, either public or private, depending on who should have access to the add-on.

4. Click “Deploy” to publish the add-on.

Users can now import the custom functions by browsing the Google Workspace Marketplace and installing the add-on.

5.5 Resources for Further Learning and Improving Skills

To enhance your custom functions building skills and expertise, consider exploring the following resources:

– Google Apps Script documentation (

– Stack Overflow community ( Search and ask questions related to custom functions and Google Sheets.

– Online courses and tutorials: Many platforms offer in-depth courses and tutorials on JavaScript and Google Apps Script.

– Books: Numerous books delve into varying levels of expertise in custom functions and JavaScript, catering to beginners and advanced users.


Q: Can I distribute my custom functions as a paid add-on?

A: Yes, Google Workspace Marketplace allows developers to monetize their add-ons by configuring the payment settings during the publishing process.

Q: Can I restrict access to my custom functions?

A: You can control access to your custom functions by managing the sharing settings of your Google Sheet or script and by choosing the appropriate deployment type when publishing an add-on.

Module Summary and Key Takeaways:

In this module, we covered crucial aspects of deploying and sharing custom functions in Google Sheets. We explored best practices for documenting code, managing versions, sharing functions with collaborators, and distributing them as add-ons. With these skills, you are now ready to maximize the impact of your custom functions and contribute to the Google Sheets community at large.
