I have received a few questions recently relating to working with data spread across multiple sheets. In general, if the data is in the same layout, keep it in one table.
Stop Power Query from automatically setting Data Types

Saving time
When working with some large data sets in Power Query it may be useful to default your Close and Load option to Connection Only rather than a Table. That way if you do strike an issue it won’t take ages to load to data.
Power Query shortcut for Adults
The shortcut to display the Queries & Connections Task Pane is easy to remember. It is Adults Only!
To display or hide the Queries & Connections Task Pane you use. These keys are pressed in sequence, not held down.
So only adults allowed in Power Query.
