This work shows how Excel can be leveraged to tackle configuration problems. We demonstrate this by presenting the full development cycle of a PC-configurator prototype. We articulate our demonstration by exemplifying several important points. First, Excel can be used to import raw products and services data. Second, these data can be used by a constraint modelling to correctly instantiate a set of configuration rules. Third, any update to the data like addition of new components can be performed without altering the modelling. Fourth, dedicated Excel GUIs can be used for interactive product and service configuration.
