Demand Planning using historical data

What would be the best way to develop a dynamic forecasting tool in Excel using historical data? Each week new data would be added that I would like to influence future forecasts. I would like like to be able to forecast new items by connecting them to "like" items.
 
Collect a Table of Data with sufficient number of fields to allow future analysis

Add a report to extract suitable data and sort

Forecast using a suitable algorithm based on your business model, This may be as simple as a straight linear regression/extrapolation or it may feed into a whole business model.
