Open-source Python libraries  

Python in Excel comes with a standard set of Python libraries provided by Anaconda through a secure distribution. Use these Python libraries to simplify your data analysis, find patterns and hidden insights, and visualize your data with plots. 

Core Python in Excel libraries 

The following open-source libraries are available with Python in Excel by default. They've been imported with the statements listed. 

  • Matplotlib. Import statement: import matplotlib.pyplot as plt

  • NumPy. Import statement: import numpy as np

  • pandas. Import statement: import pandas as pd

  • seaborn. Import statement: import seaborn as sns

  • statsmodels. Import statement: import statsmodels as sm

Note: These core libraries are also listed in the Python in Excel initialization task pane. Access the initialization task pane by selecting Formulas > Initialization in the Excel ribbon. This task pane is currently read-only and shows the initialization settings for your Python in Excel runtime.

How to import libraries 

In addition to the core libraries, you can import additional libraries available through Anaconda. Import Python libraries into Excel using a Python import statement in a Python in Excel cell, such as import numpy as np. This statement imports the NumPylibrary and assigns it the alias np. After entering this import statement into a Python cell, you can refer to the NumPy library as np throughout the Python formulas in that workbook. 

Tip: To ensure that your libraries are imported before your Python formulas run, enter your import statements and any settings on the first worksheet in your workbook. If desired, you can reserve the first worksheet specifically for the import statements and settings.

Important: Not all libraries use the import statement format import [library] as [name]. For example, to import the beautifulsoup4 library, use the import statement from bs4 import BeautifulSoup. See the documentation for each library to learn the recommended import statement.

List of recommended libraries 

The following table shows a subset of the open-source libraries provided by Anaconda that you can use with Python in Excel. The libraries Matplotlib, NumPy, seaborn, statsmodels, and pandasare imported by default. The additional libraries listed in the table are not automatically imported, but you can choose to import them if desired. 

Important: To protect your data security, these libraries will not have the ability to make network requests or access your files and data on your local machine. To learn more, see Data Security and Python in Excel.
