The left pane in Power Query Editor is the Queries pane, which displays all of the queries that are currently defined in the workbook.
Each query appears as a separate item in the list and is represented by its name. You can rename, delete, and create new queries using the options in this pane.
Additionally, the Queries pane allows you to organize your queries into folders to keep them better organized. By default, queries are organized into a single folder, but you can create new folders and move queries between folders as needed.
You can also use the search box at the top of the Queries pane to search for specific queries by name or other attributes, such as their source or type. This can be helpful when you have a large number of queries and need to find a specific one quickly.
Overall, the Queries pane in Power Query Editor provides a central location for managing and organizing your queries, making it easier to work with and analyze your data.
When you select a query from the left pane, its data is displayed in the center pane, where you can shape and transform the data to meet your needs.
