CSV ⇄ JSON Converter

A two-way CSV ⇄ JSON converter: paste CSV to get a typed array of objects (RFC-4180 quoting, numbers/booleans/null inference, quoted cells stay strings) or flip direction to serialize a JSON array back to CSV. Delimiter chips (comma/tab/semicolon) with auto-detection, row/column counts and copy.
