Convert JSON arrays or objects into CSV-ready tables right in your browser — no upload, no server round-trip.
将 JSON 对象数组展平为二维表格的逻辑:
{"a":1} 显示为 {"a":1}),不展开为多列。null / 缺失字段留空;嵌套数组同样序列化为 JSON 字符串填入单元格(不按索引展开为多列)。导出建议带 UTF-8 BOM,以便 Excel 正确识别中文不乱码。全程纯前端解析,数据不上传。
= + - @ 开头的单元格自动加单引号前缀,防止 Excel / WPS 将其当作公式执行;页面预览保持原始数据。
| Item | Formula / Note | Source / Standard |
|---|---|---|
| Header mapping | object keys become headers; missing keys stay empty | RFC 8259 / RFC 4180 |
| Field quoting | fields with commas, quotes or newlines need quoting | RFC 4180 |
| Flattening | flatten nested objects into dotted keys or embedded JSON | RFC 8259 |
