How do I get source data in Power BI?

In the fast-paced landscape of business intelligence, Power BI stands tall as a transformative tool that empowers organizations to glean actionable insights from their data. At the heart of this process lies the crucial step of sourcing data – the raw material that fuels the analytics engine. In this detailed guide, we will delve into the various methods employed to obtain source data in Power BI, offering a comprehensive roadmap for both beginners and seasoned users.

The Significance of Source Data in Power BI

Before embarking on our exploration of sourcing data in Power BI, it’s essential to comprehend the significance of source data. In the Power BI context, source data represents the raw, unprocessed information that organizations aim to analyze, visualize, and draw insights from. This data can originate from diverse platforms, including databases, spreadsheets, cloud services, and online sources.

Methods of Sourcing Data in Power BI

1. Importing Data

One of the most straightforward methods to bring data into Power BI is through importing. This method is ideal for static or periodically updated datasets. Users can import data from a variety of file formats such as Excel, CSV, JSON, and more. To initiate the import process, navigate to the Home tab, select “Get Data,” and choose the relevant source. This method is efficient for scenarios where real-time updates are not critical.

2. DirectQuery

For organizations requiring real-time analytics, DirectQuery is a game-changer. This method enables Power BI to retrieve data directly from the source without the need for importing it into the Power BI file. DirectQuery supports various data sources, including SQL Server, Oracle, and other relational databases. By establishing a live connection, users ensure that their visualizations consistently reflect the latest data, making it a valuable tool for dynamic and rapidly changing datasets.

3. Power Query

Power Query is a powerful and versatile data transformation tool integrated seamlessly into Power BI. This tool enables users to connect to various data sources, perform data transformations, and clean the data before loading it into Power BI. Power Query is particularly beneficial when dealing with disparate data sources, allowing users to shape the data into a consistent and analyzable format. This method is crucial for ensuring data quality and relevance in the analytics process.

4. Live Connections

Live connections are an excellent option for those dealing with large datasets or scenarios where leveraging the processing capabilities of the original data source is advantageous. Instead of importing the data, Power BI establishes a live connection to the source, ensuring that the data is queried in real-time. This method is commonly used for databases such as SQL Server, Azure SQL Database, and other data warehouses.

A Deep Dive into Power BI’s Data Sourcing Methods

Importing Data

Importing data into Power BI is a straightforward process, but it’s crucial to understand the implications of this method. When data is imported, it becomes part of the Power BI file, allowing for offline analysis. However, this approach is not suitable for real-time analytics, as the data needs to be refreshed manually or on a scheduled basis.


DirectQuery, on the other hand, offers a real-time connection to the data source. This means that any changes in the source data are immediately reflected in the Power BI reports and dashboards. While this provides a dynamic and up-to-date view of the data, it’s essential to consider the performance implications, as real-time querying may put a strain on the source system.

Power Query

Power Query is a versatile tool that allows users to shape and transform data before loading it into Power BI. Its user-friendly interface enables data cleaning, merging, and filtering, ensuring that the data is in the desired format for analysis. Power Query supports a wide range of data sources, making it a go-to tool for data preparation.

Live Connections

Live connections provide the best of both worlds – a direct link to the source data without the need for importing. This method is advantageous when dealing with large datasets that may exceed Power BI’s storage capacity. However, it’s essential to consider the network and performance implications, as live connections depend on the availability and speed of the source system.

Frequently Asked Questions (FAQs)

Q1: Can I combine data from multiple sources in Power BI?

Absolutely! Power BI provides robust tools, especially through Power Query, to merge and combine data from various sources. This ensures a holistic analysis by bringing together related information.

Q2: Is it possible to schedule data refreshes for imported data?

Yes, Power BI allows users to set up scheduled refreshes for imported data. This ensures that reports and dashboards always reflect the latest information, even for static or periodically updated datasets.

Q3: What is the difference between Import and DirectQuery?

The key distinction lies in where the data is stored. Import loads the data into the Power BI file, providing offline access, while DirectQuery accesses the data directly from the source, offering real-time insights but with potential performance considerations.

Q4: How do I handle data errors or inconsistencies?

Power Query comes to the rescue! It provides a comprehensive set of tools for cleaning and transforming data. Users can address errors, inconsistencies, and missing values before loading the data into Power BI, ensuring high-quality and reliable analytics.


Sourcing data is the foundational step in the Power BI journey, and understanding the diverse methods available is crucial for effective analysis and visualization. Whether you opt for importing, DirectQuery, Power Query, or live connections, each method has its strengths and considerations.
