CSV ↔ JSON Converter

CSV → JSON (Array of Objects): The first row becomes the keys for each object. Each subsequent row becomes an object.

CSV → JSON (Array of Arrays): Each row (including header) becomes a nested array.

JSON → CSV: Expects an array of objects with consistent keys, or an array of arrays. Object keys become the CSV header row.

Delimiters: Choose comma, tab, semicolon, or pipe to match your data format.

Quoted Fields: Fields containing the delimiter, quotes, or newlines are automatically quoted in CSV output.
