Overview Spreadsheets that are used in the real world are full of errors and cause companies and organizations to lose millions of dollars every year. Finding and correcting spreadsheet errors is a very difficult and time-consuming activity. Observing that all errors in spreadsheets result from updates or changes applied to the spreadsheet - be it during the creation of a new spreadsheet or while adapting an existing one - an obvious alternative to debugging is to prevent errors by making these update operations safe. The authors have created an extension to Excel, called Gencel, that is based on the concept of a spreadsheet template, which captures the essential structure of a spreadsheet and all of its future evolutions.
