📋 CSV 表格处理CSV Table

把 CSV 转换为 JSON 或 Markdown 表格，或行列转置；还可按列排序、按列筛选数据行。支持逗号、分号、Tab 及自定义分隔符，全部在本地完成。Convert CSV to JSON or a Markdown table, or transpose rows and columns; also sort or filter data rows by column. Comma, semicolon, Tab or custom delimiter — all local.

① 输入 CSV① Input CSV

② 排序与筛选② Sort & filter

排序、筛选与按列去重仅作用于「CSV → 其他」方向，作用于表头之外的数据行。Sort, filter & column dedupe apply only to the “CSV → else” direction, on data rows (excluding the header).

③ 输出③ Output

📚 CSV 引号与转义规则📚 CSV quoting & escaping

CSV 没有强制标准，但存在通用规则：① 含逗号（或分隔符）、换行、引号的字段必须用双引号包裹；② 字段内的双引号写成两个连续引号（`""`）转义；③ 是否「首行是表头」依文件而定——本工具按首行当表头处理。例如 a,"b,c",d 是三个字段（第二个值为 b,c）。CSV has no strict standard but common rules: ① fields containing the delimiter, newlines or quotes must be wrapped in double quotes; ② embedded quotes are escaped by doubling (`""`); ③ whether the first row is a header depends on the file — this tool treats it as the header. E.g. a,"b,c",d is three fields (the second value is b,c).

分隔符不限于逗号：分号、Tab、竖线等同样常见（取决于区域设置与导出工具）。本工具支持逗号/分号/Tab/竖线及自定义分隔符，并带完整的引号解析与转义（含字段内换行），因此可以正确处理「被引号包裹、内含分隔符与换行」的复杂单元格。Delimiters are not limited to commas: semicolons, tabs and pipes are common (depending on locale and exporting tool). This tool supports comma/semicolon/Tab/pipe plus a custom delimiter, with full quote-aware parsing and escaping (including embedded newlines), so complex quoted cells with embedded delimiters and line breaks parse correctly.
