JSON to CSV Converter

Flatten JSON arrays into rows for spreadsheets.

JSON input (array of objects)

Delimiter

Include header row

CSV output

Columns come from the union of all object keys. Empty cells are padded so rows stay aligned; nested values are serialized as JSON strings.

Как пользоваться

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.
