When You Should Use Python in Microsoft Excel, and When It Could Be Time to Migrate to Power BI?

Getting your Trinity Audio player ready...

Python is a high-level interpreted language that dominates the fields of data analytics, machine learning, and automation. Its latest incorporation with Microsoft Excel represents a significant expansion of the capabilities of this already strong spreadsheet program. Excel has long been the go-to application for business users looking to organize, analyze, and visualize data. It has provided a solid foundation for anything from basic computations to complicated financial models. However, as businesses expand and data grows more complicated, Excel alone may not be able to handle massive amounts of data or do complex analyses.  

The addition of Python to Excel seeks to close this gap. It embeds Python's computational power and flexibility directly into your Excel worksheets, enabling more complex analytics and data manipulation immediately within the platform you're already comfortable with. This is a game changer for business users, who can now take advantage of Python's capabilities without leaving Excel's user-friendly interface.  

While Excel remains an excellent tool for data analytics, especially with the inclusion of Python, there are times when it may not be sufficient. When dealing with massive datasets, real-time analytics, or advanced visualizations, it may be time to examine other choices, such as Power BI. In this blog post, we'll look at when you should utilize Python in Microsoft Excel and when it's better to switch to Power BI.  

What Python in Excel Means for Business Users

The integration of Python into Microsoft Excel is a significant milestone that opens up a plethora of opportunities for business users. Let's explore what this change means for you and your team.  

Enhanced Data Analytics

First and foremost, Python's entry into Excel dramatically enhances the data analytics capabilities of the software. Python is known for its powerful libraries like pandas for data manipulation, Matplotlib for data visualization, and scikit-learn for machine learning. By bringing these functionalities into Excel, business users can now perform more complex analyses without having to switch between multiple platforms. Imagine running machine learning models or creating advanced visualizations right within your Excel workbook; that's the level of sophistication Python brings to the table.

User-Friendly for Analysts

One of the most appealing aspects of this integration is its user-friendliness. You don't need to be a Python expert to take advantage of its capabilities. Excel has introduced a new function called `PY`, which allows you to input Python code directly into Excel cells. This means that even those with limited coding experience can now perform advanced analytics. The learning curve is minimal, especially if you're already familiar with Excel's interface.

Security Features

When it comes to business data, security is always a top concern. The good news is that Python code in Excel runs on the Microsoft Cloud, providing enterprise-level security. The Python code operates in a hypervisor isolated container using Azure Container Instances, ensuring that your data is secure and compliant with industry standards. This adds an extra layer of confidence for businesses looking to perform secure, complex analytics.

Team Collaboration

Collaboration is key in any business setting, and Python in Excel excels in this area as well. The integration makes it easier than ever to share workbooks that contain Python code. Team members can interact with and refresh the analytics without worrying about additional installations or setups. This is particularly beneficial for teams that are spread across different locations or those who rely on real-time data for decision-making.

When to Consider Migrating to Power BI from Excel?

While the integration of Python into Excel has significantly expanded its capabilities, there are certain scenarios where you might find Power BI to be a more suitable solution. Let's explore some of these situations.


Excel is incredibly versatile, but it has its limitations, especially when it comes to handling large datasets. As your business grows, you may find that Excel starts to slow down or even crash when dealing with extensive data. Power BI, on the other hand, is designed to handle large volumes of data with ease. It can connect to various data sources and perform analytics on millions of rows without breaking a sweat. So, if your business is scaling and you're dealing with increasingly large datasets, Power BI could be the better option.

Advanced Visualizations

Python libraries like Matplotlib and seaborn offer a wide range of visualization options within Excel. However, Power BI takes data visualization to the next level with its intuitive drag-and-drop interface and a plethora of built-in visualizations. Whether you're looking to create simple bar charts or complex 3D models, Power BI provides a more comprehensive set of tools for your data storytelling needs.  

Real-Time Data Analysis

In today's fast-paced business environment, real-time data analysis is often crucial for making timely decisions. While Python in Excel offers robust analytics capabilities, it doesn't natively support real-time data analysis. Power BI shines in this aspect, allowing you to create dashboards that update in real-time and can be shared across the organization. This enables you to monitor key performance indicators (KPIs) and make data-driven decisions on the fly.

Cost-Benefit Analysis

When choosing between Python in Excel and Power BI, it's essential to consider the cost-benefit analysis. Excel with Python offers a low-cost solution for advanced analytics, especially if your team is already well-versed in Excel. However, as your data needs grow, you may find that the time and effort spent managing large Excel files outweigh the benefits. Power BI, while requiring a separate subscription, offers more advanced features and scalability, potentially providing a higher return on investment for businesses with more complex data needs.

In conclusion, while Python in Excel has opened new doors for data analytics, there are specific scenarios where Power BI may offer a more efficient and scalable solution. By understanding the strengths and limitations of each platform, you can make a more informed decision that aligns with your business needs.

The Business Impact  

Choosing between Python in Excel and Power BI is not just a technical decision; it has far-reaching implications for your business. Both tools offer unique advantages and limitations that can significantly affect your organization's data analytics capabilities, efficiency, and overall performance.

Data Size & Complexity

As the DataCamp article points out, Excel has limitations on the amount of data it can handle—just over 1 million rows and 16 thousand columns. This can be a bottleneck for businesses dealing with large and growing datasets. Power BI, in contrast, can handle much larger volumes of data, making it a more scalable solution for enterprises.

Flexibility vs. Automation

Excel is highly flexible and allows for custom solutions, but this flexibility often comes at the cost of manual effort and time. Power BI, on the other hand, excels in automation. It allows you to set up dashboards that update in real-time, reducing the manual work required and enabling quicker decision-making.

Cost Implications

While Excel is commonly included in Office 365 subscriptions that many businesses already have, Power BI requires a separate subscription. The cost of a Power BI PRO license is $10 per user per month. Businesses need to weigh these costs against the benefits each platform offers. For instance, the scalability and automation features of Power BI could offer a higher return on investment for larger, more complex data analytics needs.  

Security Concerns

Data security is crucial for any business. Power BI provides a more secure environment for sharing reports and dashboards, allowing admins to control the level of access each user gets. Excel, although it offers some level of password protection, exposes the underlying data, posing a potential security risk.

In summary, the choice between Python in Excel and Power BI will have a substantial impact on your business's data analytics capabilities. It will affect how you scale your operations, how quickly you can make informed decisions, and how securely you can share information within your organization. Therefore, it's crucial to consider these factors carefully to choose the platform that best aligns with your business needs.
