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

If you're parsing the file with a FOR command in a batch file a semicolon works (;)

REM test.bat contents

for /F "tokens=1-3 delims=," %%a in (test.csv) do @Echo %%a, %%b, %%c

---

;test.csv contents (this line is a comment)

;1,ignore this line,no it shouldn't

2,parse this line,yes it should!

;3,ignore this line,no it shouldn't

4,parse this line,yes it should!

OUTPUT:

2, parse this line, yes it should!

4, parse this line, yes it should!
