# \lstinputlisting for a normal text file?

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?

Welcome to TeX.sx! Please add a minimal working example (MWE) that illustrates your problem. Use package filecontents (see texdoc filecontents) to include an example file file.txt. –  Kurt Oct 4 '12 at 18:50
Do you want a caption with this listing? If not, you can just use \input{file.txt}. –  Werner Oct 4 '12 at 18:52
If you want plain text, with the option for a box around it and line numbers, you might consider fancyvrb. –  G. Poore Oct 4 '12 at 19:39

Perhaps you have set a language using \lstset. You can disable the language by using the empty language:
\lstinputlisting[language={}]{file.txt}
