export lang files to excel/csv

Hi, I tried to work with https://github.com/ufirstgroup/laravel-lang-import-export but I receive an error message on artisan command: "[InvalidArgumentException] There are no commands defined in the "lang-export" namespace." I even open an issue on it: https://github.com/ufirstgroup/laravel-lang-import-export/issues/1

I tried https://github.com/tedslittlerobot/laravel-lang-tools and same here... I have an error. https://github.com/tedslittlerobot/laravel-lang-tools

Is there any other working package to export excel/csv of all langs under resources>lang>en

Thanks in advanced! Lio.
