=PY( df = xl("A1:G10000", headers=True); # Remove duplicates df = df.drop_duplicates(); # Fill missing values with median df["Price"] = df["Price"].fillna(df["Price"].median()); # Standardize text df["Product"] = df["Product"].str.strip().str.lower(); df ) The cleaned DataFrame spills back into your grid instantly – 10,000 rows processed in under 1 second. VLOOKUP/XLOOKUP are great for one match. But merging three tables with different keys? Python’s merge() is your friend.
=PY( orders = xl("Orders!A1:D5000", headers=True); customers = xl("Customers!A1:C2000", headers=True); products = xl("Products!A1:B1000", headers=True); merged = orders.merge(customers, on="CustomerID").merge(products, on="ProductID"); merged["TotalValue"] = merged["Quantity"] * merged["UnitPrice"]; merged ) One line of code replaces dozens of helper columns and volatile array formulas. Excel pivot tables are interactive but slow on large data. Python’s groupby + agg gives you the same results instantly: Excel Python- fei su gao ding shu ju fen xi yu chu li
The xl() function pulls Excel ranges into a pandas DataFrame. After processing, Python returns the result – which can be a single value, a DataFrame (automatically spilled into cells), or a plot. 1. Rapid Data Cleaning (Seconds, Not Hours) Manually cleaning messy data is a nightmare. With pandas: =PY( df = xl("A1:G10000", headers=True); # Remove duplicates
=PY( from sklearn.linear_model import LinearRegression import numpy as np df = xl("HistoricalData!A1:B100", headers=True); X = df[["Month"]].values; y = df["Sales"].values; model = LinearRegression().fit(X, y); prediction = model.predict([[13]]) # next month prediction[0] ) Result appears in the cell – 95, 103.2, whatever your model predicts. No need to export. Excel charts are decent but limited. Python’s seaborn creates publication-quality plots directly in the worksheet: Python’s merge() is your friend
For decades, Microsoft Excel has been the world’s most accessible data tool. But as datasets grow into the hundreds of thousands of rows, Excel’s traditional formula engine and manual operations become sluggish, error-prone, and limiting.
