Can a CSV file have a comment?

Question

Is there any official way to allow a CSV formatted file to allow comments, either on its own line OR at the end of a line?

I tried checking wikipedia on this and als

Answer 1

A Comma Separated File is really just a text file where the lines consist of values separated by commas.

There is no standard which defines the contents of a CSV file, so there is no defined way of indicating a comment. It depends on the program which will be importing the CSV file.

Of course, this is usually Excel. You should ask yourself how does Excel define a comment? In other words, what would make Excel ignore a line (or part of a line) in the CSV file? I'm not aware of anything which would do this.
