Data preparation in Power BI consulting focuses on ensuring data quality, accuracy, and usability. Power BI consulting begin by extracting data from various sources such as Excel, databases, or cloud platforms. Power Query is used for cleaning, transforming, and shaping data, addressing inconsistencies like duplicates, missing values, or incorrect formats. Relationships between data tables are established to build a cohesive data model. Consultants optimize the data structure for performance and scalability, ensuring efficient report generation. This process ensures that the data foundation is robust, enabling reliable insights and visualizations.
