CSV 表格和 JSON 数组一键互转：正确处理引号里的逗号、换行和转义引号这些最容易翻车的细节，分隔符可选逗号、分号、Tab 或竖线。适合导数据、调接口、整理表格。Convert CSV tables and JSON arrays both ways, with the tricky details handled properly — commas, newlines and escaped quotes inside quoted fields — and delimiter choices (comma, semicolon, tab, pipe). For data wrangling, API debugging and spreadsheets.
CSV → JSON 时第一行作为字段名（表头），所有值都按字符串输出——这与多数电子表格导出行为一致；如果需要数字类型，转换后请在目标系统里再做类型处理。For CSV → JSON, the first row becomes the field names and all values are strings — matching most spreadsheet exports. If you need numbers, coerce types in the target system afterwards.
