工具介绍
文本去重排序按行处理内容：重复行只保留首次出现，可同时去掉首尾空格、删除空行、忽略大小写差异。 The line deduplicator keeps the first occurrence of each line, with optional whitespace trimming, blank-line removal and case folding.
去重后还能按字母、数字大小或字符长度排序，适合整理关键词表、邮箱列表、商品编码等逐行数据，结果可直接复制或导出 TXT。 After deduplication you can sort alphabetically, numerically or by length — handy for keyword lists, email lists or product codes, with copy and TXT export.

常见问题
重复行保留哪一条？Which duplicate is kept?
保留首次出现的那一条，后面的重复行计入“移除行数”。The first occurrence is kept; later copies count as removed.
忽略大小写后原样会变吗？Does case folding change the output?
不会。只用于判断是否重复，输出仍保留首次出现时的原始大小写。No. It only affects duplicate detection; output keeps the original casing of the first occurrence.
空行怎么算？How are blank lines counted?
勾选“删除空行”时所有空行都被移除并计入移除；不勾选则原样保留。With “Drop blank lines” on, every blank line is removed and counted; otherwise they stay.
排序会把数字按文本排吗？Does sorting treat numbers as text?
选“按数字大小”时会按数值排序，非数字行排在最后；其他方式按文本比较。“Numeric” compares values and pushes non-numeric lines last; other modes compare as text.
