Do I need to uninstall Excel to use Power BI?

No, Excel and Power BI are complementary tools, not competing ones. You can continue using Excel for data entry and management while Power BI handles transforming that data into interactive dashboards and sharing them across the organization.

How does automatic refresh work for a Power BI report connected to Excel?

If the Excel file is stored in SharePoint or OneDrive for Business, Power BI Service can schedule automatic refreshes without manual intervention. If the file is on a local computer, the Power BI Gateway must be installed to enable scheduled refreshes.

What advantage does Power Query offer when connecting Excel to Power BI?

Power Query lets you apply reproducible transformations to Excel data, such as combining sheets, filtering rows, converting data types, and creating calculated columns. Each time the dataset is refreshed in Power BI, Power Query automatically re-executes those transformations on the most current data.

How to Connect Excel to Power BI: Step-by-Step Guide

By Manuel Cosini · February 19, 2026 · 5 min read

Excel remains one of the most widely used tools in businesses worldwide for managing data — and for good reason. It is flexible, accessible, and practically everyone knows how to use it. But when reports grow in complexity, when multiple people need to update the same file, or when analysis timelines become unsustainable, it is time to take the next step: connecting Excel to Power BI. This guide walks you through the process step by step and explains the concrete advantages you gain by integrating both tools.

Why Connect Excel to Power BI?

Excel and Power BI are not competing tools — they complement each other. Excel excels at data entry and management, ad hoc calculations, and working with structured data in an individual context. Power BI, on the other hand, is designed to transform that data into interactive visualizations, share reports across the organization, and update dashboards automatically.

Connecting the two tools means your team can continue working in Excel — as it already does — while Power BI handles transforming that data into dashboards that any manager can access without needing to open a file, apply filters manually, or wait for an update email.

Step 1: Prepare the Excel File Correctly

Before connecting Excel to Power BI, the file needs to be well structured. Power BI works best with data organized as Tables (not simple ranges). This means:

A clear header row in the first row, with no merged cells.
Homogeneous data in each column (a date column should contain only dates, not a mix of text and dates).
No blank rows or columns within the data range.
Converting the range to an Excel Table (Ctrl + T) so Power BI automatically detects new records on each refresh.

This step may seem simple, but it is one of the most important. Many refresh and transformation issues in Power BI trace back to a poorly structured Excel file.

Step 2: Import the Excel File into Power BI Desktop

Once the file is prepared, the connection process in Power BI Desktop is straightforward:

Open Power BI Desktop and click Get Data on the Home tab.
Select Excel Workbook from the list of available connectors.
Browse to the .xlsx file on your computer or on SharePoint/OneDrive and click Open.
In the Navigator, select the sheets or tables you want to import. If you converted ranges to Excel Tables, they will appear listed by name.
Click Transform Data if you want to review or modify the structure before loading, or Load if the data is ready to use as is.

Clicking "Transform Data" opens the Power Query editor, where you can apply additional transformations before loading data into the Power BI model.

Step 3: Use Power Query to Transform Excel Data

Power Query is the native ETL engine in Power BI and is especially powerful when working with Excel data. From the Power Query editor you can:

Combine multiple Excel sheets into a single table.
Remove unnecessary columns and rename others.
Convert data types (for example, changing a text column to a date column).
Filter rows based on specific conditions.
Create calculated columns with business logic.
Join the Excel table with data from other sources (databases, APIs, other files).

Every step you perform in Power Query is recorded as a reproducible transformation. This means that each time the dataset is refreshed in Power BI, Power Query automatically re-executes all those transformations on the most current data from your Excel file.

Step 4: Connect an Excel File in SharePoint or OneDrive for Automatic Refresh

If the Excel file is stored locally on your computer, dataset refreshes in Power BI Service will only work if you have the Power BI Gateway installed. A more practical option for teams is to store the Excel file in SharePoint or OneDrive for Business and connect to it from there.

To do this, instead of connecting to a local file, in the "Get Data" step select SharePoint Folder or use the direct URL of the file in SharePoint. This allows the dataset in Power BI Service to refresh automatically on a defined schedule (for example, every hour or every day), without manual intervention and without needing the Gateway.

Step 5: Build the Dashboard and Publish to Power BI Service

With the data loaded and transformed, the next step is building the dashboard in Power BI Desktop. You can create bar charts, line charts, maps, KPIs, and tables that update automatically with each dataset refresh. Cross-filtering between visuals — the feature that automatically filters all other visuals when you click on a bar in a chart — is available without any additional configuration and is one of the most valued capabilities Power BI users experience.

Once the report is ready, you publish it to Power BI Service (the online version) and can share it with your entire organization. End users can access it from a browser or from the Power BI mobile app, without needing Excel or Power BI Desktop installed.

When Should You Migrate from Excel to Power BI?

Not every business needs to migrate all its reports to Power BI at once. But there are situations where the migration delivers clear value:

When the report is shared with many people and manually updating the Excel file each time is an operational burden.
When the Excel file has become so large that it is slow or unstable.
When you need to combine Excel data with other sources (databases, CRM, ERP).
When executives need real-time access to data from any device.
When multiple versions of the same file are circulating by email and no one knows which one is definitive.

The good news is that migrating from Excel to Power BI does not mean abandoning Excel. You can keep your spreadsheets as data sources and use Power BI exclusively for the visualization and distribution layer. Over time, many companies consolidate their sources into a Data Warehouse and remove spreadsheets from the critical chain, but that transition can happen gradually.

Concrete Advantages of Integrating Excel with Power BI

Companies that connect their Excel files with Power BI typically report immediate benefits: eliminating manual reports that previously took hours, giving executives the ability to access up-to-date data at any time without asking the analytics team, and a significant reduction in errors caused by broken formulas or outdated file versions.

Additionally, Power BI supports Row-Level Security, which means different users can see the same report but only with the data relevant to their role or region. This is impossible to implement at scale in a shared Excel file.

At Okun Data, we help businesses take this step in an organized way: we audit their current Excel files, identify which data has analytical value, design the data model in Power BI, and build dashboards that teams genuinely use every day.
