ExcelToDss is an Excel add-in that facilitates the creation of scripts (.dss files) for the OpenDSS program. ExcelToDss generates scripts from Excel tables, which promotes the use of formulas to calculate power apparatus parameters.

To produce a solution, ExcelToDss invokes OpenDSS and imports the results back into Excel. With a single-click, all voltages, currents, powers, losses, and monitor information are made available in Excel.

ExcelToDss does not have a user interface to create power system models; instead, it requires entering data into tables.

ExcelToDss requires Microsoft Excel 2007 and OpenDSS (developed by Roger Dugan at EPRI):
