JSON から CSV への変換について

よくある質問
What JSON structure works best?
An array of flat objects (e.g. [{id:1, name:'Alice'}, {id:2, name:'Bob'}]) produces clean CSV columns and rows.
Is it safe to process sensitive API data?
100% safe. Your JSON payload is parsed purely in your browser's JS engine and is never sent to any server.
