What strategies do Power BI consultants use to integrate and transform data?

Power BI consultants integrate and transform data using Power Query and ETL (Extract, Transform, Load) best practices. They connect various sources such as SQL databases, Excel, APIs, cloud services, and third-party applications. Cleaning and structuring the data involve handling missing values, duplicates, and formatting inconsistencies. Power BI consulting services apply data transformations such as filtering, merging, and aggregating to create a structured dataset. They optimize data load performance using incremental refresh and minimize redundant data. By ensuring data quality, Power BI consulting services enable businesses to work with accurate, reliable, and well-structured datasets for analytics and reporting.
