Look inside

Acme Widgets, a manufacturing company, manually logs its supplier invoices on spreadsheets in Google Workspace. Your task is to free the staff from this tedious task by creating an add-on that automatically extracts and records useful information from invoices. You’ll set up a Google Cloud Platform (GCP) account, implement and deploy the add-on, and create Document AI processors for processing invoices from multiple regions. You’ll add a CardService that improves the user experience by letting them select which files to process. You’ll use the Document AI REST API to process the invoices’ image data and write the processed data to a spreadsheet, enhancing the user interface. When you're done, you’ll have created a basic, easy-to-use Google Workspace add-on that extracts and records invoices in multiple formats, leaving the Acme Widgets staff free to focus on more productive tasks.

This project is designed for learning purposes and is not a complete, production-ready application or solution.
