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

If you need something like:

  │ A                              │ B
──┼────────────────────────────────┼───
1 │ #My comment, something else    │
2 │ 1                              │ 2

Your CSV may contain the following lines:

"#My comment, something else"
1,2

Pay close attention at the 'quotes' in the first line.

When converting your text to columns using the Excel wizard, remember checking the 'Treat consecutive delimiters as one', setting it to use 'quotes' as delimiter.

Thus, Excel will split the text at the commas, keeping the 'comment' line as a single column value (and it will remove the quotes).
