Recently, Microsoft announced the integration of the Python programming language into Excel – highlighting a huge advancement in the field. Combining Python’s powerful data manipulation, analysis, and visualization libraries with Excel’s user-friendly interface enables users to leverage the strengths of both these tools. Excel, the foundational data management, analysis, and visualization tool, takes a significant leap toward its analytical capabilities by integrating the Python functionality.

How does Python in Excel work?

The integration of Python in Excel highlights a significant advancement in data analytics. With the ‘PY’ function integrated within Excel, users can now access the vast libraries of Python. Tasks such as data visualization, advanced analytics, and machine learning are available at the fingertips. All within the familiar boundaries of an Excel spreadsheet. This eliminates the need for separate installations or shifting between platforms. This is a boon for someone who works on both of these platforms. Also, data teams may already have workflows that involve manipulating data using Python, and then moving this into Excel for user-friendly and shareable visualizations. By combining the two, Microsoft could cut out unnecessary work to streamline the process.

Limitations of Excel in Advanced Data Analytics

When given extensive datasets or if advanced statistical analysis is required, Excel’s capabilities fall short. Here are some common limitations:

  • Performance: Excel becomes sluggish when handling large datasets, leading to slower processing times.
  • Limited Statistical Analysis: Excel does offer basic statistical functions, but it lacks the sophistication for more advanced statistical analysis, such as regression analysis or Machine Learning (ML).
  • Reproducibility: It can be challenging to maintain a record of data transformations and analyses performed in Excel.
  • Data Visualization: Excel’s charting capabilities, while useful, are not as advanced as compared to specialized data visualization libraries available in Python.
  • Automation: Automating repetitive tasks in Excel often requires complex macros and Visual Basic for Applications (VBA) coding skills.

Main Features of the Python Excel Integration

A main feature of this integration is the ability to enter Python code directly into an Excel cell. With this feature, calculations can be done securely within the Microsoft Cloud. The results – data points, plots, or visualizations are specified in the Excel worksheet. This seamless process enables users to pair Excel’s conventional features such as formulas, charts, and pivot tables with Python’s data analysis tools.

Another main enhancement is Excel’s capability to source data. Its built-in connectors and the Power Query feature streamline the importing of external data processes into Python-activated workflows. This optimizes the analytics process. With Anaconda’s Distribution operating on Azure, users can now access some of the most popular Python libraries, such as pandas for data manipulation, statsmodels for statistical modeling, and tools such as Matplotlib.

Advantages of Integrating Python with Excel:

The integration of Python with Excel addresses these limitations and offers several advantages:

  • Data Handling: Python’s libraries, such as Pandas and NumPy, are excellent at data manipulation, cleaning, and transformation, enabling efficient data preparation for analysis.
  • Advanced Analytics: Python displays a wide range of libraries for advanced analytics, including Scikit-Learn for ML, NLTK for Natural Language Processing (NLP), and statsmodels for statistical modeling.
  • Data Visualization: Matplotlib and Seaborn offer extensive data visualization capabilities, enabling the creation of complex charts and graphs.
  • Automation: Python enables you to automate repetitive tasks in Excel more easily, making it a valuable tool for data validation, cleaning, and report generation.
  • Reproducibility: Python scripts can be documented and version-controlled, ensuring transparency in data analysis.
  • Custom Functions: You can create custom Python functions and use them as Excel functions, extending Excel’s functionality to suit exclusive analytical needs.
  • Interactivity: Python libraries such as Dash and Flask enable the creation of interactive dashboards and web applications that can be embedded within Excel workbooks.
  • Scalability: Python’s performance and scalability are excellent for handling larger and more complex datasets.

Setting Up Python Integration in Excel

Before you can leverage the power of Python within Excel, you need to enable the Python Add-In on Excel. Following are the steps to integrate Python within Excel:

  1. Open Excel and click on the File
  2. Select Options to open the Excel Options dialog box.
  3. Click on “Add-Ins” available in the left menu.
  4. In the Add-Ins section, choose Excel Add-ins from the Manage drop-down menu, and click Go
  5. In the Add-Ins dialog box, check the box for Python Add-in to enable Python scripting in Excel.

With the Python Add-in enabled, you can access Python functionality using the Python tab on the Excel ribbon. Once you have enabled the Python Add-in, you can start writing and running Python scripts

Explanation of = PY function

Microsoft states that the new = PY function enables users to seamlessly integrate Python’s analytical capabilities within Excel’s grid. You can use it like any other Excel macro or function. This new function works securely within the Microsoft Cloud while ensuring that the enterprise-level security is at par with Microsoft 365’s compliance standards. This function’s key highlight is user privacy. It forbids Python code from accessing user identity and offers an additional layer of security when a user opens workbooks from the internet by isolating the workbooks in unique containers.

Microsoft Excel States that “Data from your workbooks is sent via the built-in xl() Python function, and the output of the Python code returns as the result of the =PY() Excel function.”

To use the new =PY function to access Python in Excel, enter “=PY” in the Excel cell, followed by the appropriate Python code. Once the code is executed, the results will be displayed in the Excel worksheet.


Integrating Python into Excel signifies a transformative synergy that allows users to leverage the full potential of both tools. This dynamic combination streamlines compound data manipulation and analysis and enables automation, customization, and data-driven decision-making. Python’s versatility and Excel’s user-friendly interface create a powerful amalgamation that can benefit professionals across various industries.
