如何使用「BibTeX 格式化（整理 .bib 文件）」？How do I use the BibTeX Formatter & Cleaner?
把 .bib 内容粘贴到左侧（或点“打开 .bib 文件”），在选项里选择缩进、字段顺序和要删除的字段，右侧会实时给出整理后的结果和问题列表。确认无误后点“复制”或“下载 .bib”，替换原文件即可。Paste your .bib on the left (or open a file), choose indentation, field order and fields to drop; the cleaned output and a list of issues update live on the right. Copy or download the .bib and replace your original.
为什么要“保护标题大写”？Why protect capitals in titles?
很多 BibTeX 样式（如 IEEEtran、plain）会把标题转成句首大写，导致 “BERT”“Transformer” 被改成小写。勾选后会给缩写和专有名词加上 {} 保护，例如 {BERT}。Many styles (IEEEtran, plain …) lowercase titles, turning “BERT” into “bert”. This option wraps acronyms and capitalised words in braces such as {BERT}.
会改动 @string 和注释吗？Does it touch @string and comments?
@string、@preamble 会原样保留并放在最前面；条目之间的说明文字默认保留。@string and @preamble entries are kept unchanged at the top; text between entries is kept by default.
支持中文参考文献吗？Does it handle Chinese references?
支持。条目键、作者和标题都可以包含中文，整理时不会改动中文内容。Yes — keys, authors and titles may contain Chinese and are left intact.
