Why should I use a human readable file format?

Question

Why should I use a human readable file format in preference to a binary one? Is there ever a situation when this isn\'t the case?

EDIT: I did have this as an explana

Answer 1

I guess its not good in most situations probably. I think the main reason for these formats such as JSON and XML is because of web development, and general use over the web where you need to be able to process data on the user-side and you cant necessarily read binary. A good example of a bad case to use a human readable format would be any thing non textual such as images, video, audio. Ive noticed the use of non-binary formats being used in web development where it does not make sense, I feel guilty!
