Common questions

Frequently asked questions

How do I escape a double quote inside CSV?

Inside a quoted field, represent one literal double quote as two consecutive double quotes.

Should I use a backslash before the quote?

Not for this CSV syntax. Doubling the quote is the supported escaping rule.

Why does the parser complain after the quote instead of at the quote itself?

The quote is interpreted as a valid closing quote; the following ordinary text reveals that the field closed too early.
