Microsoft Power Query enhances data cleaning and import in Excel

Microsoft's Power Query is a tool in Excel that helps users clean and import data efficiently. Initially an add-in, it became a native feature in 2016, allowing users to organize data from various sources and refresh it easily. To clean data, users can split email addresses into separate rows and extract names using the Power Query Editor. This process involves selecting data, using delimiters, and renaming columns, making data management simpler and more organized. Power Query also allows importing data from other spreadsheets. Users can transform data by promoting headers, unpivoting columns, and renaming them. This ensures that any changes in the source data can be updated in the new spreadsheet with a simple refresh.
