Quick answer
In RFC 4180 CSV, a field that starts with a double quote must end with a matching quote.
CSV Unclosed Quote
In RFC 4180 CSV, a field that starts with a double quote must end with a matching quote. If the closing quote is missing, the parser cannot know where the field ends.
Common causes
- Forgetting to close a quoted field before the next comma or newline.
- A line break or comma inside a quoted value without closing the quote first.
- Copy-pasting from a broken or truncated CSV.
How to fix
- Ensure every field that starts with " ends with " on the same line.
- To include a newline inside a field, keep the field in quotes and use "" for an escaped quote.
- Validate your CSV with an online validator to get the exact line and column.
Examples
Bad
name,note Alice,"Hello world Bob,"Bye"
Good
name,note Alice,"Hello world" Bob,"Bye"
