How to replace null with space?

I want to make each line with 80 characters. If any line contains only 5 characters and remaining is null, then i want to make it as 80 characrets where 5 is original characters and remaining 75 characters will be null..


NULL can come in between the line, at begining the line or at end of line.

I have tried using

Code:

 
 tr '\0' '\40' < inputfile >> outputfile

But it did not work... can somebody help me.
