和“列表格式转换”有什么区别？How is this different from List Converter?
“列表格式转换”专门做“每行一项 ↔ 逗号分隔”两种格式的互转；这个工具可以在换行、逗号、分号、Tab、空格、竖线和任意自定义分隔符之间任意转换，并能自动识别输入用的是哪种分隔符，适合处理从表格、日志或其他程序复制出来的各种列表。List Converter is specifically for switching between one-item-per-line and comma-separated lists. This tool converts between new lines, commas, semicolons, tabs, spaces, pipes and any custom separator in any direction, and detects which separator the input uses, so it suits lists copied from spreadsheets, logs or other programs.
引号选项有什么用？What are the quote options for?
单引号会把每一项写成 'a'（项目里的单引号会按 SQL 规则写成两个），适合 SQL 的 IN (...) 条件；双引号按 JSON 规则加引号并转义，配合逗号分隔符就是 JSON 数组的内容，在外面加上 [ ] 即可。Single quotes write each item as 'a' (a single quote inside is doubled, SQL-style), ready for an SQL IN (...) clause. Double quotes quote and escape items JSON-style; with a comma separator that's the inside of a JSON array, so just add [ ] around it.
分隔符是怎么自动识别的？How is the separator detected automatically?
“自动识别”按以下顺序判断：有换行就按行分隔，否则依次检查 Tab、分号、逗号（含中文逗号和顿号）、竖线，最后才是空格。用逗号、分号或 Tab 分隔时支持 CSV 式的双引号，例如 "北京, 中国" 会被当作一项。需要其他符号时选择“自定义”，可用 \n 和 \t 表示换行和 Tab。输出沿用原来的分隔符（包括自定义分隔符和中文逗号），含分隔符的项会重新加上双引号；空行默认忽略，不算作项目。Auto-detect works in this order: if there are line breaks, each line is an item; otherwise it checks for tabs, semicolons, commas (including the Chinese comma and enumeration comma), pipes and finally spaces. With comma, semicolon or tab separators, CSV-style double quotes are honoured, so "Paris, France" counts as one item. Choose Custom for anything else; \n and \t stand for a new line and a tab. The output keeps the original separator (including a custom one or the Chinese comma), items that contain the separator are quoted again, and blank lines are ignored by default.
