Python in Excel is now officially available for Windows users of Microsoft 365 Business and Enterprise. Last August, Microsoft partnered with Anaconda to introduce an exciting addition to Excel by integrating Python, making it possible to seamlessly combine Python and Excel analysis into the same workbook, with no setup required. Since then, we've brought the power of popular Python analysis libraries like pandas, Matplotlib, and NLTK to countless Excel users.
Of course, a subscription to Microsoft 365 Business or Enterprise is required to use Python in Excel.
Open Excel, click "Formula" - "Insert Python":
Select the cell and type "=PY":
Click on the PY button that pops up and the input box turns green "PY":
Next we can analyze the data with Python processing.
We have the following data:
At this point, two things happen: one is that you know the Python language, and the other is that you don't know the Python language.
If you know how to use the Python language
Enter it in the PY input box:
sample_df = xl("IrisDataSet8[#全部]", headers=True)
sample_df.describe()
Generate a dataframe to expand the description information:
Next, the matplotlib library is imported to generate the scatterplot:
import matplotlib.pyplot as plt
plt.scatter(xl("IrisDataSet10[sepal_length]"), xl("IrisDataSet10[sepal_width]"))
plt.xlabel('sepal_length')
plt.ylabel('sepal_width')
plt.title('Sepal length and width analysis')
Generate images to observe the relationship between variables:
Linear regression statistical modeling was introduced for seaborn:
import seaborn as sns
sample_df = xl("IrisDataSet11[#全部]", headers=True)
sns.regplot(data = sample_df[["sepal_length","petal_length"]], x = "sepal_length", y = "petal_length")
Plot to find a linear relationship between a dependent variable and one or more independent variables:
Introducing the pandas matrix diagram:
from pandas.plotting import scatter_matrix
sample_df = xl("IrisDataSet13[#全部]", headers=True)
columns_to_plot = ["sepal_length", "sepal_width", "petal_length", "petal_width"]
categories = sample_df["species"].unique() # Get unique categories
colors = {category: i for i, category in enumerate(categories)}
scatter_matrix(sample_df, c=sample_df["species"].apply(lambda x: colors[x]), figsize=(6, 6), alpha=0.8)
Generate a graph matrix for analyzing the relationships between pairs of variables in a data set:
If you don't know Python
It doesn't hurt that copilot will help you!
In Excel, click on copilot and a chat box pops up on the right asking copilot to write code for Python to perform linear regression:
Copy this code into the PY input box and make the appropriate changes as prompted.
And, soon Python in Excel with copilot will be available. At that time, copilot will be directly based on natural language to automatically generate py code and run directly out of the results, directly eliminating the copy and paste modified steps.
Let's expect this to happen!
Many people say, why not just implement it in Python?
My answer is that Python's installation environment alone keeps 90%'s out of the door, and some people will never want to leave Excel for the rest of their lives.
All that's needed to make this happen is a Microsoft 365 Business subscription.
