Power BI Desktop is the crucial component of Microsoft Business Intelligence. It enables a user to import, analyze, and create reports out of complex information, streaming in from multiple data sources. The free version of Power BI allows the user to analyze data, create live reports, and publish them on the Internet.
With the Pro version of Power BI, the user can share those reports or dashboards with other users and stakeholders and provide advanced analytics without consuming much time. It also supports Power Query and Power Editor, which gives it an edge over other Business Intelligence Tools.
So, let’s get into the topic and create a report using the free version.
What is Power BI?
Microsoft Power BI is a collection of software services, tools, processes, and connectors that enables users to create custom reports and dashboards based on complex information, streaming in from multiple data sources.
On Power BI, users can visualize raw business data in the form of graphs and charts based on different constraints and attach them as tiles on live dashboards. A tile is a single visualization of any dataset embedded on the dashboard.
Power BI architecture bridges the gap between data and decision-making with the help of BI Components such as Power Query, Power View, and Power Map. These Power BI components provide accurate answers to business questions using AI algorithms and Natural Language Processing.

How does Power BI Desktop work?
The process of creating a report has four main steps or stages. Let’s briefly discuss these steps in this section.
Connect with Data Sources
Power BI Desktop data sources include Excel spreadsheets, CSV files, Q-data feed, online services, and data on the cloud. This data could be structured, semi-structured, or unstructured, depending on the business type.
The first step in the process is connecting with the above data sources to import data. After importing the data from different sources, you can move forward with transforming and filtering the data based on various constraints. However, you cannot import more than 10 GB of data in the software. If your data is bigger than 10 GB, you either have to go for the Power BI Pro version or run direct queries on different data sources.
Transform Data & Create Models
Using Power Query Editor, you can extract valuable information, remove anomalies, and add some conditions for a better understanding of the data. It is similar to sculpting a block of wood by cutting the edges, removing extra wood, shaving off the projections, and adding other ingredients to make it look as intended.
You can also change columns and data types and add default values into the columns with null values. If you do Business Analytics on Tableau, the transformation of data would be exhausting. However, Power BI components convert it into a drag-n-drop play for data modeling.

Visuals are the graphical representations of the data you stored in a model. Microsoft Power BI Desktop provides drag-n-drop features through which you can visualize the raw business data in the form of charts, graphs, maps, and KPIs.
After creating the visuals, they can be attached to the dashboards or live reports in the form of tiles. Custom visuals also help you identify the problems in various departments and the market behavior and make better decisions based on them.
Create & Share Reports
A report in a collection of visuals created from different data models. A report might consist of multiple dashboards with custom visualizations. Live reports, on the other hand, show real-time analysis of the data, streaming in from multiple sources.
These visually rich reports, analyzing complex data, can be shared with other people in your organization with the help of Power BI Desktop online.

Getting Started with Power BI Desktop
To get started, you need to first connect the data with the interface. For this tutorial, an Excel Spreadsheet is taken as the sample data source. You can download the spreadsheet from Microsoft documents or use any other data source of your choice.
Now, let’s start with the tutorial, and build our first report in Power BI.
- Open Microsoft Power BI Desktop, and you will see various sources from which you can import data. If you are using an Excel sheet, then select Excel from the toolbar. If you want to load the data from an on-cloud server or data warehouse, then you have to use Power BI Service.
- Once the data gets imported from the desired data source(s), a Navigator window will show all the data you have imported. Here, you can clean or transform your data as per the requirements or move forward by pressing the Load button
- On the right-hand side of the BI Desktop interface, all the columns from different datasets will be displayed with an icon representing their data type. For example, the date column will be represented by the calendar icon, and the columns such as Sales, Profit, Gross Sales, and Discounts having a numerical value will be represented by sigma
Moving on to the next step of data visualization, Power BI provides AI features to interact with the data by executing your queries in natural language.
- To do so, double-click on the interface of the BI page. Then, a small dialog box will appear with the search bar where you can write your query
- To create the visual, type in the names of the columns and the type of graph or chart you want, and you will get it done in seconds. For example, if you want to create a pie chart for Sales in different countries, type in sales country pie, and click on Turn this Q&A into a standard visual
Similarly, you can create multiple visuals with the help of Power Q&A.
- Now, filter these visuals for the details based on specific constraints. Like in the image below, when selected Gross Sales of Canada in Maps, the other two visuals highlighted the sales for that particular region
- Once all the visuals are added, export the report as a Power BI template or a PDF file
