表形式のデータを扱う際、TSV（Tab Separated Values）はそのシンプルさから多くの場面で利用されています。しかし、近年、より柔軟なデータ構造と処理のしやすさから、NDJSON（Newline Delimited JSON）への変換ニーズが高まっています。特に、API連携やログ解析、あるいは複雑な階層データを含むコンテンツ管理など、現代的なアプリケーション開発において、NDJSONはその真価を発揮します。このツールは、お手持ちのTSVファイルを、1行ごとに独立したJSONオブジェクトとして扱えるNDJSON形式へ、簡単かつ正確に変換します。データの整合性を保ちつつ、次世代のデータ活用へとスムーズに移行できるよう、ぜひご活用ください。
