Convert DOE2.3 files to EnergyPlus format

edit

Hello, while I am trying to convert my .inp files to .idf format, I came across a few tools:

1. DOE2Translator - This could not convert properly. I guess spaces in u-names are creating the problem. Even though some objects were converted, their properties and values are not completely not transferred.
   • Do I have to first convert the DOE2.3 file to DOE2.1 file and use the translator? How to convert DOE2.3 to DOE2.1?
   • Or do I have to change the u-names without having spaces and special characters?
2. BTAP - This is converting only a few of the geometry objects. Is there a way to convert all other objects like schedules, constructions, materials, people, zones etc.,
3. DOE2EP - I could not find this program. Is this and DOE2Translator the same?

Any help is greatly appreciated
