Tool for collection analysis (cllection in xlsx, output data in txt file)

[Moro]

I know that there are plenty of tools and methods to organize cards collections but I've decided to write my own so that I can easily capture any data I need in the form I prefer. All configuration is in simple Python script (input xlsx file, output txt file). I just wanted to be able to easily control missing cards while watching online auctions ;-) Maybe it will be useful for someone, feel free to fork
