EnergyPro uses a number of custom FUNCTIONS which will not work in DOE2.2. Because of these functions, I believe that it is not possible to convert an EnergyPro DOE2.1e model to DOE2.2.

The equivalent file that you're looking for is the .inp file generated by eQUEST. However, eQUEST uses DOE2.2 as the simulation engine while EnergyPro uses DOE2.1E, and although there are similarities, the two input file types are not compatible. You will either have to modify your spreadsheet to analyze DOE2.2 input files or attempt to convert the DOE2.2 file from eQUEST to a DOE2.1E file (.inp to .DOE). You can find information on the difference between the two file formats and how to manually convert from DOE2.2 format to DOE2.1E format on the doe2 website.
