Dynamic Excel Budget Forecasting with Monte Carlo Simulation

financial modeling monte carlo pandas numpy forecasting
Prompt
Create a Python script using pandas and numpy to generate a sophisticated budget forecasting model that performs Monte Carlo simulation across multiple expense categories. The script should import an existing Excel template, run 10,000 randomized scenarios using historical variance, and output a probability-weighted forecast with confidence intervals. Include visualization of potential budget outcomes using matplotlib, with special attention to handling irregular financial distributions and potential outlier management.
