Does it handle quoted fields?

Yes! Fields containing commas, quotes, or newlines that are properly quoted (per RFC 4180) are handled correctly.

Does it auto-detect data types?

Yes, the converter attempts to detect numbers and booleans in your CSV data and converts them to their JSON equivalents rather than leaving everything as strings.

What delimiter does it support?

The converter supports comma-separated values by default. Tab-separated values (TSV) are also detected automatically.

How are headers handled?

The first row is treated as headers and used as JSON object keys. Each subsequent row becomes a JSON object in the output array.
