The workstation (PC) version of FactSet comes bundled with an Excel add-in. The add-in is NOT available for FactSet Connect (Mac) or FactSet Web users.
The FactSet add-in comes bundled with templates that support financial modeling and analysis, including valuation. These templates allow you to both model different inputs or scenarios and to refresh your model with 'live data' supplied by FactSet. It is recommended that FactSet be launched for the templates to function; otherwise, the add-in by itself may not work as intended. Please note that once a template has been saved outside of the add-in, the data will no longer update.
