Excel 2013 cannot open simple text file with .acc extension

[gacuxz]

Inside .acc file is a simple text, but the mighty Excel tries to open it like some kind of database. It is asking for accounts, sources, passwords etc. and finally it cannot open it at all. It can open this file if I change extension to something else like .txt or .xls. How can I turn off this useless function of Excel 2013? The Excel of 2003 just opens it without any question.

Awesome. Damn Microsoft makes one more stupid function and no one even knows how to turn it off. I bet no one even knows what kind of problem I have. Feels like real MS teamwork. Wonder when the salvation will come and Microsoft will go for something like excrements alteration or something. Maybe there they would be better at something.
