I want to create a script in order to take an epw file, process it, and then convert it back to epw. The reason for writing a script is because I want to process the epw file 500 times and as a result create 500 new epw files. Until now I was 'brewing on a small scale' using the weather converter program to convert the epw to csv, then process it in excel, and at the end convert it back to epw. Any suggestions on scaling up?
