How can a dataflow be created in Power BI?

Creating a dataflow in Power BI primarily involves using the Power BI service alongside Power Query. Dataflows enable users to connect to various data sources, transform the data into a usable format, and store it in a workspace for further analysis and reporting.

When using the Power BI service with Power Query, users can leverage the powerful data transformation and cleansing capabilities provided by Power Query. This tool allows users to define complex data transformation processes visually, simplifying the preparation of data from multiple sources into a single location where it can be used in reports and dashboards.

While compiling data from tables, importing data from external databases, or using Excel sheets can be part of data management and reporting processes in Power BI, these options do not specifically refer to the creation of dataflows. A dataflow is a structured entity in Power BI that is created through the Power BI service and involves the Power Query editor, making it essential to emphasize the specific method of utilizing these tools to create a dataflow effectively.
