What Are Connectors in Power BI?

To use Power BI for anything meaningful, you first need to get your data into it. That essential first step is handled by connectors, which act as the gateways between your raw data sources and your powerful reporting dashboards. This article will walk you through what Power BI connectors are, why they are so important, and how you can start using them today.

What Exactly Is a Power BI Connector?

Think of a Power BI connector as a specialized translator and courier. Your data might live in an Excel sheet, a complex SQL database, a cloud app like Salesforce, or your Google Analytics account. Each of these sources structures and communicates its data in a completely different way.

Without a connector, you'd be stuck manually exporting files (like CSVs) and then trying to clean and import them. It's a slow, error-prone process that leaves you with stale data.

A connector automates this entire exchange. It knows exactly how to:

• Authenticate: It handles the login process securely, whether it's through a simple username/password, an API key, or an OAuth screen you’re already familiar with.
• Translate: It sends requests to the source system's API in a language it understands and then translates the data it gets back into a standardized format that Power BI can work with.
• Structure: It presents the data to you in a clear, tabular format, letting you choose which tables, fields, or objects you want to pull into your report.

In short, a connector does the highly technical work of fetching data, so you can focus on building visualizations and finding insights.

Why Connectors Are so Important in Power BI

Connectors are far more than just a convenience, they are central to the whole concept of modern business intelligence. They unlock the ability to get your hands on data from countless sources and mash it up to tell a deeper story.

Create a Single Source of Truth

Most organizations have data scattered everywhere. Sales data is in Salesforce, website data is in Google Analytics, ad spend is in Facebook Ads, and a dozen different Excel sheets are being emailed around. It’s chaotic and leads to people making decisions based on different, often conflicting, information.

Connectors let you pull all that data into one central place: your Power BI model. You can finally see how your Facebook ad spend directly impacts Shopify sales, all in a single dashboard. This unified view is the foundation for creating a single source of truth that your entire team can trust.

Automate Reporting with Fresh Data

One of the biggest time-sinks in any business is the repetitive weekly or monthly report. It usually involves someone spending hours downloading data, pasting it into a spreadsheet, updating some pivot tables, and exporting charts to a PowerPoint.

By using a connector in Power BI, you can schedule data refreshes. You can tell Power BI to connect to your data sources every morning at 7 AM, for instance. It automatically pulls in the latest data, updates all your visuals, and has the report ready for you before you've even had your first cup of coffee. This frees you from the manual work, helping you focus on analysis, not just data collection.

The Different Types of Connectors in Power BI

Power BI offers over 150 unique connectors, and a ton more through third-party partners. Most fall into one of the following groups:

1. File Connectors

These are often the starting point for most Power BI users. They allow you to pull data directly from individual files stored on your computer or a shared drive like SharePoint or OneDrive. This group includes common types like:

• Excel Workbook (.xlsx, .xlsb)
• Text/CSV (.csv)
• XML (.xml)
• JSON (.json)
• PDF (.pdf)
• SharePoint Folder

2. Database Connectors

For businesses with more formal data storage, database connectors are essential. These connectors pull information directly from organized databases, which are often managed by IT teams. Because they connect to the database itself, the data is usually well-structured and reliable.

• SQL Server database
• MySQL database
• PostgreSQL database
• Oracle database
• SAP HANA database

3. Power Platform Connectors

Since Power BI is part of Microsoft’s larger suite of business tools, called the Power Platform, it has dedicated, high-performance connectors for other services in this ecosystem. These include:

• Power BI datasets
• Power BI dataflows
• Dataverse (the database for Power Apps data)

4. Azure Connectors

For organizations using Microsoft’s Azure cloud computing platform, there's a huge list of connectors built and optimized. This is ideal for analyzing large data sets.

• Azure SQL Database
• Azure Synapse Analytics
• Azure Data Lake Storage
• Azure Cosmos DB

5. Online Services Connectors

This is where things get really interesting for marketing, sales, and operations teams. These connectors let you pull data directly from the SaaS apps and cloud software you use to run your business every day. No more exporting CSVs from each app – you can connect right to the source.

• Salesforce (for CRM and sales data)
• Google Analytics (for website traffic and user behavior)
• HubSpot (a new native Power BI connector)
• SharePoint Online List
• Microsoft Dynamics 365
• Adobe Analytics

A Step-by-Step Guide: How to Use a Connector in Power BI

Let's walk through a simple, practical example: connecting Power BI to an Excel workbook on your local drive. The process highlights the fundamental steps you’ll take for almost any connector.

Step 1: Open Power BI and Select ‘Get Data’

On the "Home" tab, the “Get Data" icon is the main access point. Clicking on this brings up a drop-down menu with icons of the more common sources, like Excel Workbook and SQL Server. For most of the available connectors, you'll need to press the More… prompt at the bottom of the panel.

Step 2: Find and Select Your Connector

The "Get Data" dialog box will pop up, listing all available connectors categorized on the left. You can search at the top or choose a category.

For our example, select File > Excel Workbook and click Connect.

Power BI will then ask you to find the file locally. Once you select your Excel file, click Open.

Step 3: Use the Navigator to Choose Your Data

After a moment, the Navigator window appears. The connector reads your file and displays what's inside. For an Excel workbook, it will show each worksheet (indicated by a plain sheet icon) as well as any official Tables (indicated by a blue-header icon) you might have.

You can click on an item to preview the data on the right. Select the checkbox next to the tables you want to use in the project you are working on. We recommend connecting to Excel Tables over raw worksheets for their reliability.

Step 4: Load or Transform Your Data

In the bottom-right of the Navigator window, you have two key choices:

• Load: This option will immediately load the data, with little or no changes, directly to the Power BI model. You can begin visualizing with that data right away. This is often the case for smaller datasets that have been tidied and do not need more preparation work.
• Transform Data: This option opens up Power Query Editor, providing an advanced platform where you can clean and prepare your data. In Power Query Editor, you can fix data types, clean unwanted columns, rename fields, and much more to properly shape your data before loading it into the model.

Once you click either Load or Transform, you are on your way to utilizing Power BI!

Best Practices to Remember

While the process is straightforward, following a few tips will save you a lot of headaches in the future:

• Use the "Transform" Option: Unless you are completely sure your dataset is as clean as needed, always start by using 'Transform Data.' Even checking and confirming data types in Power Query is a time-saver you'll appreciate later on.
• Go Right to the Source: Before choosing 'Web' from the 'Get Data' menu, check if there is a dedicated connector available for that specific service. For example, if you want data from Google Analytics, use the Google Analytics connector rather than 'Web' for more efficient authentication and data parsing.
• Think About Credentials: If you're connecting to a company's database or an organizational account, ensure you have all necessary credentials beforehand. Many refresh failures arise from password or API changes or token expiration.

Final Thoughts

Connectors are the very first - and most vital step - in any worthwhile data analysis project in Power BI. They act as your data collection army and automate tedious tasks, allowing you to bring together data from dispersed sources into a unified dashboard.

Setting up these connectors and building your data relationships correctly still includes a learning curve. That is exactly why we built Graphed.
