Frequently Asked Questions
Does it handle commas inside values?▾
Yes. Values containing commas should be wrapped in double quotes, following standard CSV format. The parser handles this correctly.
Are types auto-detected?▾
Yes. Numbers become JSON numbers, "true"/"false" become booleans, and everything else stays as strings.
