Introduction

In today’s data-driven world, the ability to seamlessly integrate and analyze data from various sources is crucial. This blog post aims to guide you through the process of connecting data from different file types in Power BI, tailored for professionals like business analysts and data enthusiasts.

Note: This blog post only focuses on getting data from files, we will cover several other types of connectors in future blog posts.

What is Power BI?

In very simple terms, Power BI is a tool that lets you visualize your data and share insights. Power BI offers a wide variety of functionalities that we will dive deep into in a future blog post.

Types of files supported by Power BI

• Excel (.xlsx, .xlsm): The most common format for storing data in spreadsheets.
• Comma-Separated Values (CSV): A simple format used to store tabular data.
• XML Files (.xml): Used for structured data storage and transfer.
• Text Files (.txt, .csv): Basic file format for storing data in plain text.

Step-by-Step Guide to Connect Data from Files

Accessing Power BI

The very first step would be to download and open the power BI desktop. The first screen that will pop up will ask you to connect data from recent files or the most used connectors.

Connecting to an Excel file

1. ‘Get Data’: Navigate to the ‘Home’ tab and select ‘Get Data’. There are two approaches:

• Clicking the icon reveals a comprehensive list of all available connectors in Power BI.

• The down arrow displays frequently used data sources.

2. ‘Select File’: Opt for ‘Excel workbook’ and navigate to the desired file. In this instance, we’re using Microsoft’s ‘Financial Sample’ workbook.

Once you click on your desired file, a Navigator window will pop up. We will click on the worksheet that we want to use.

Once selected, a preview screen will appear on the right, which will showcase your data.

3. Now you will have two options. You can either click on Load or Transform Data

Load: It will directly load your data into Power BI without making any changes to the data. You can use Load when you do not want to make any changes to the existing data.

Transform Data: Opens the Power Query Editor, allowing you to modify and optimize your data for analysis. We’ll explore the Power Query Editor in greater depth in future posts.

Connecting Other File Types

The process is similar for CSV, XML, and text files, with minor differences in the file selection step.

Tips and Best Practices

• Organize Your Data: Ensure your data is well-organized in the source file for easier analysis.
• Handle Errors: Be prepared to manage common errors like missing data or incorrect formats.

Conclusion

Connecting data from various file types in Power BI can significantly enhance your data analysis process. With this guide, you’re now equipped to start integrating and visualizing your data in new and insightful ways.
