Google Document AI

Introduction

Google Document AI is a powerful tool that allows users to extract structured data from various types of documents, including invoices and contracts. It is trained on a vast number of structured and unstructured documents, making it capable of extracting information from tables as well as key-value pairs outside of tables.

To use Google Document AI, you can simply drop your document in PDF format into the provided space, and the tool will extract the relevant data for you. Additionally, you can also use Document AI as an API to programmatically extract data from documents.

To set up and use Google Document AI, you need to create a project in the Google Cloud Console and set up the required authentication. Once you enable the Document AI API, you can choose the appropriate processor based on the type of document you are working with. It's important to select the correct processor, as it determines how well the tool can extract data from your document.

To use the Document AI API, you can refer to the open-source code examples provided by Google. These examples demonstrate how to extract data from documents using different processors, such as the generic form parser or the document OCR processor. The extracted data can then be processed and saved in a structured format, such as a CSV file.
