JSON to CSV Converter
Flatten JSON arrays into rows for spreadsheets.
Columns come from the union of all object keys. Empty cells are padded so rows stay aligned; nested values are serialized as JSON strings.

概要
Paste a JSON array of objects to get CSV rows, with a column for every key found and a header row included by default.
Cells containing your delimiter, quotes or line breaks are wrapped and escaped automatically, so the output opens cleanly in Excel or Sheets.
