Limiting number of characters in a line

I have a problem that I don't think is unique, but I haven't been able to find a resolution via the usual tools (Google, forums, etc).

I work for a localizer of text heavy software. Our developers normally use a converter to pull text out of a file and insert it into the program. This text is normally input into an Excel file since it has to correspond with files/locations in the program.

Since the space on the screen of the program is limited, we often face character limits when inputting text into Excel. Now, one cell might hold up to 255 characters, and I could restrict that with data validation, but within one cell I need to restrict each line (with a hard return) to 30 characters to fit on the screen.
So for example I have a row of cells that look like:
Hello, my name is Amejin. I like pizza, beer, and bowling.

Which need to look like:
Hello, my name is Amejin. I[HR]
like pizza, beer, and bowling.

Does anyone know a simple way to do this, or do I need to look for a macro and a VB expert?
