CSV to JSON FAQ

Can I treat the first row as headers?

Yes. The CSV controls let you keep the first row as headers or convert every row as plain column data.

Does it detect numbers and booleans automatically?

Yes. Numeric and boolean-looking values are inferred during CSV to JSON conversion for cleaner output.
