import xlwings as xw
from sklearn.linear_model import LinearRegression
import pandas as pd

# Connect to Excel
wb = xw.Book('capacity_planning.xlsx')
sheet = wb.sheets['Data']

# Fetch data
data = sheet.range('A1').options(pd.DataFrame, header=1, index=False).value

# Prepare and train model
model = LinearRegression()
model.fit(data[['Time']], data['Demand'])

# Predict future demand
next_periods = pd.DataFrame({'Time': [len(data) + i for i in range(1, 13)]})
predictions = model.predict(next_periods)

# Output predictions to Excel
sheet.range('E1').value = ['Time', 'Predicted Demand']
sheet.range('E2').options(index=False).value = next_periods.assign(Demand=predictions)

Utilizing Automated Formulas and Scripts

Excel's robust capacity for formula optimization becomes crucial in this stage. Use array formulas and VBA scripting to automate repetitive tasks. Automated processes like these reduce manual intervention, thus decreasing the likelihood of error and increasing efficiency. Implement VBA for custom formula automation and scenario testing:
