This document discusses Power Query and its capabilities for harvesting and transforming data from various sources. Power Query is a self-service ETL tool that is part of the Power BI suite and allows users to query, transform, and load data in Excel without needing to write code. It can connect to databases, files, web pages, and other sources to extract and combine data using a formula language called M. The document provides an overview of Power Query's history and functionality.
