二进制 XNOR 运算（同或）XNOR Binary Values
把两个或多个二进制数按位做 XNOR（同或）运算：先按位 XOR，再全部取反，两个数在该位相同时结果为 1，不同时为 0；多个数时，该位上 1 的个数为偶数结果就是 1。可以每行一组分别计算或所有数一起计算，位数不同时右端对齐左边补 0，可设置最少位数、显示竖式和十进制结果。适合学习逻辑门、比较两个二进制数哪些位相同和数字电路练习，数据在本地处理。Apply bitwise XNOR to two or more binary values: XOR them and invert the result, so with two values a bit is 1 where they match and 0 where they differ; with more values it is 1 where an even number of them have a 1. Work each line separately or combine all values; different lengths are right-aligned with leading zeros. Set a minimum width, show the working and see the result in decimal. Handy for learning logic gates, finding which bits of two values agree and digital-logic exercises. Processed locally.
CSV 加引号（按需或强制）Add CSV Quotes
给 CSV/TSV 每个字段都加上双引号：可选只给含分隔符/引号/换行的字段加引号（标准写法），或强制给所有字段加引号（方便导入挑剔的程序）。自动识别分隔符，正确处理已有引号。Add double quotes around every CSV/TSV field. Quote only fields that need it (the standard style), or force-quote every field for picky importers. The delimiter is detected and existing quotes are handled correctly.
CSV 去引号（去掉不必要的字段引号）Remove CSV Quotes
去掉 CSV/TSV 里不必要的双引号：解析后再按“仅必要时加引号”的规则重新输出，含分隔符/引号/换行的字段仍保留引号，其它字段变成裸文本。Strip unnecessary double quotes from a CSV or TSV. The file is parsed and rewritten with quotes only where needed — fields with the delimiter, a quote or a line break stay quoted; the rest become bare text.
CSV 更换分隔符（逗号 / 分号 / 制表符）Change CSV Delimiter
把 CSV/TSV 的分隔符换成另一种：逗号、分号、制表符或竖线。自动识别原分隔符，带引号和换行的单元格正确转换，适合在美式 Excel 和欧洲 Excel 之间互转。Switch a CSV/TSV from one delimiter to another: comma, semicolon, tab or pipe. The original delimiter is detected and quoted cells with line breaks convert correctly — handy between US and European Excel.
CSV 更换引号样式（双引号 / 单引号）Change CSV Quote Style
把 CSV 字段的引号在双引号和单引号之间转换：有些数据库导出用单引号，本工具可改成标准双引号 CSV，或反过来。内部引号会正确转义。Convert CSV field quotes between double and single quotes. Some database exports use single quotes; this tool turns them into standard double-quoted CSV, or the other way round. Inner quotes are escaped correctly.

把 CSV/TSV 转成纯文本：可选用空格、制表符或自定义符号连接字段，去掉引号，适合粘贴到笔记、邮件或需要非 CSV 格式的地方。Turn a CSV or TSV into plain text: join fields with spaces, tabs or a custom separator and drop the quotes — handy for notes, email or anywhere that does not want CSV.
CSV 删除列Delete CSV Columns

CSV 删除单元格内的逗号（千分位等）Delete Commas Inside CSV Cells
去掉 CSV 单元格内部的逗号（常用于清除千分位：1,250 → 1250），可选只处理“看起来像数字”的单元格，避免误伤地址等文本。分隔符本身不变。Remove commas inside CSV cells (often thousands separators: 1,250 → 1250). Optionally only touch cells that look like numbers so addresses stay intact. The delimiter itself is unchanged.
CSV 补齐不完整行（短行补空单元格）Fill Incomplete CSV Records
把列数不足的 CSV 行补齐到与最宽行（或表头）相同的列数，空位填空白或指定值。自动识别分隔符，方便导入要求“每行列数一致”的程序。Pad short CSV rows to the width of the widest row (or the header) with blanks or a value you choose. The delimiter is detected — handy for importers that require a consistent column count.
CSV 查找不完整行（列数不足）Find Incomplete CSV Records

CSV 交换两列Swap CSV Columns
交换 CSV/TSV 中的两列（按列号或表头名），其它列不动。可设置「列 A」、「列 B」、「第一行是表头」。Swap two columns in a CSV or TSV (by number or header name); every other column stays put. Settings: Column A, Column B, First row is a header.
CSV 去除单元格首尾空格Trim CSV Columns
去掉 CSV/TSV 单元格首尾的空格、制表符等空白，可选只处理指定列。表头也可以一起整理。Strip leading and trailing spaces, tabs and other whitespace from CSV/TSV cells, optionally only in chosen columns. Headers can be trimmed too.
