If you have ever wished your Bubble.io app could automatically generate, customize, and manage Google Sheets on demand, this tutorial is exactly what you need.
Google Sheets is one of the most widely used business tools in the world. And when you connect it to Bubble.io through the Google Sheets and Drive APIs with full OAuth authentication, you can turn it into a powerful, fully automated template engine that works inside your app without any manual effort.
In this tutorial, we walk you through the complete setup and automation workflow from scratch. By the end, you will have a system that can create, duplicate, customize, merge, and rename Google Sheets automatically, all triggered from inside your Bubble.io app.

Why Connect Google Sheets to Bubble.io?
Most Bubble apps that need document generation rely on third-party plugins or manual exports. These approaches are slow, limited, and hard to scale.
By connecting directly to the Google Sheets API, you unlock full programmatic control over your spreadsheets. You can create new sheets, fill them with data, apply formatting, duplicate templates, merge content from multiple sources, and rename files, all automatically, triggered by workflows inside your Bubble app.
This opens up powerful use cases for SaaS products, internal tools, and client-facing reporting systems.
Who Is This Tutorial For?
This is an advanced tutorial designed for:
Bubble.io developers building data-driven applications Teams building SaaS products that generate reports or documents Businesses that need client reporting systems built on no-code Developers building internal tools that require dynamic spreadsheet generation Anyone looking to automate Google Sheets workflows inside Bubble.io
A basic understanding of Bubble.io and the API Connector is helpful but not required. We explain every step clearly.
Tools Used in This Tutorial
Google Cloud Console Google Sheets API Google Drive API Bubble.io API Connector OAuth 2.0 Authentication
Step 1: Setting Up OAuth Access for Google Sheets and Google Drive
OAuth authentication is the foundation of this entire integration. It allows your Bubble.io app to access and manage Google Sheets on behalf of your users in a secure and authorized way.
Go to console.cloud.google.com and create a new project or select an existing one. Navigate to “APIs and Services” and enable both the Google Sheets API and the Google Drive API.
Next, go to “Credentials” and create an OAuth 2.0 Client ID. Select “Web Application” as the application type and add your Bubble app URL as an authorized redirect URI.
Once your OAuth credentials are created, copy your Client ID and Client Secret. You will need these when setting up the API Connector in Bubble.io.
Inside Bubble, open the API Connector and create a new API for Google. Set the authentication type to OAuth 2.0 and enter your Client ID, Client Secret, and the required scopes for Sheets and Drive access.
Step 2: Creating New Google Sheets Programmatically via API
With OAuth set up, the first API call you will configure is one that creates a brand new Google Sheet from scratch.
This call sends a POST request to the Google Sheets API with a title and any initial configuration you want to apply. The API returns the new spreadsheet’s ID, which you will use in subsequent API calls to modify or populate the sheet.
Inside Bubble, you can trigger this call from any workflow, giving your app the ability to generate a new spreadsheet on demand whenever a user or system action requires it.
Step 3: Duplicating Existing Sheets to Use as Templates
One of the most powerful features of this system is the ability to duplicate an existing Google Sheet and use it as a template for new documents.
This is done through the Google Drive API, which allows you to copy any file in Google Drive, including spreadsheets, and save the copy with a new name and location.
By setting up a master template sheet in Google Drive, your Bubble app can duplicate it on demand, giving every new document the same structure, formatting, and placeholder content ready to be customized.
Step 4: Performing Find and Replace Across Sheets
Once you have duplicated your template, the next step is to customize it with real data. The Google Sheets API supports batch update requests that can perform find and replace operations across an entire spreadsheet.
This means your Bubble workflow can take dynamic values from your database, such as a client name, date, project title, or any other field, and automatically replace placeholder text inside the duplicated template with real content.
This is what transforms a static template into a fully dynamic, data-driven document generated automatically by your app.
Step 5: Merging Data from Multiple Sheets
In some use cases, you may need to pull data from multiple source sheets and combine it into a single output document. The Google Sheets API supports this through a series of read and write operations that your Bubble workflow can orchestrate automatically.
Your workflow reads data from one or more source sheets, processes it as needed, and writes the combined output into your target document. This is particularly useful for client reports, financial summaries, or any document that aggregates data from multiple sources.
Step 6: Renaming and Managing Sheets Dynamically
As your system generates new documents, you will want to keep them organized and clearly named. The Google Drive API allows you to rename any file programmatically, which means your Bubble workflow can automatically assign meaningful names to every document it generates.
You can name sheets based on dynamic values like client names, project codes, dates, or any other data from your Bubble database, keeping your Google Drive organized without any manual effort.
Step 7: Automating the Full Workflow in Bubble.io
With all of the individual API calls configured and tested, the final step is to connect them into a single automated workflow inside Bubble.
A complete template generation workflow looks like this:
A trigger event occurs inside your Bubble app, such as a button click, a form submission, or a scheduled workflow The workflow duplicates your master template sheet using the Drive API It performs find and replace to insert dynamic data from your database using the Sheets API It merges any additional data from source sheets if required It renames the final document based on dynamic values It saves the new sheet URL or ID to your Bubble database for future reference
The result is a fully automated document generation system that produces customized, ready-to-use Google Sheets templates on demand, all without any manual work.
Practical Use Cases for This Integration
Client reporting systems that generate a new report sheet for each client automatically SaaS apps that produce onboarding documents or data exports in spreadsheet format Internal tools that generate project trackers or budget sheets from template structures Invoice or proposal generators that populate a standard template with deal-specific data Education platforms that create personalized progress sheets for each student
