A VERY WORK IN PROGRESS command line tool to convert Portal 2 Puzzle Maker data files (.p2c) from v14 (commercial version) to the "old" v12 (educational version). The v12 format is described here: https://developer.valvesoftware.com/wiki/P2C.
p2c_conv.py [-h] [-i INPUT] [-o OUTPUT]
Or, in some systems, it may be necessary to invoke the python interpreter explicitly:
python p2c_conv.py [-h] [-i INPUT] [-o OUTPUT]
In order to build a windows executable, you may use PyInstaller:
pyinstaller p2c_conv.py
