Dear Fakeha,
All E+ input files are text, so you can prepare them in any program which can export text. (I use Excel, for example, and export as .csv)
Similarly, output is also text, and can be analyzed by any software which can import text.

Subject: [EnergyPlus_Support] importing/exporting I/O files
Can the input files for EnergyPlus be created using some other GUI and sent over to EnergyPlus for simulation and the output files generated by EnergyPlus be sent over to other software tool for analyzing the results.
