[Tex/LaTex] \lstinputlisting for a normal text file

external fileshighlightinglistings

sometimes im using \lstinputlisting to show some code examples in my pdf. Now I just would like to insert a normal textfile. Everything is fine, I like this box around my text and the numbers every line. I just dont like that some string are bold. It's something like this:

12345 123 3123 3213H ABC12 AB 88789

So strings are bold. Somehow. I'm using \lstinputlisting{file.txt}.
How can I change that? I mean highlighting is fine for my code, that's great but in this file I dont want this. Any ideas?

Perhaps you have set a language using \lstset. You can disable the language by using the empty language:
