工具介绍
从日志、接口或聊天里复制出来的 SQL 往往挤成一行，格式化后每个子句独立成行，字段列表按逗号拆开，WHERE 里的 AND / OR 也会换行。 SQL copied from logs, APIs or chat often arrives on one line; formatting gives each clause its own line, splits the field list on commas and breaks AND / OR in WHERE.
字符串、反引号标识符与 -- / /* */ 注释原样保留；关键字大小写可一键统一，输出行数、关键字数与字符数会实时统计。 Strings, quoted identifiers and -- or block comments are preserved as-is; keyword case can be normalized, with line, keyword and character counts updated live.
- 子句换行Clause line breaks
- 字段逗号拆分Comma-split fields
- AND / OR 缩进Indented AND / OR
- 关键字大写Keyword uppercase
- 注释与字符串保留Preserves strings and comments

常见问题
会改变 SQL 语义吗？Does it change SQL semantics?
只调整空白与关键字大小写，不增删字符；字符串与注释内容不会被大写。It only adjusts whitespace and keyword case, never adds or removes tokens; strings and comments are untouched.
支持子查询吗？Are subqueries supported?
支持常见括号子查询，会额外缩进一层；多层嵌套建议检查后再执行。Common parenthesized subqueries are indented one level; review deeply nested ones before running.
存储过程能格式化吗？Can it format stored procedures?
BEGIN / END 等过程结构只做基础整理，可能不符合你的排版习惯，请手动复核。Procedural BEGIN / END blocks get only basic treatment and may not match your style — review them manually.
会上传 SQL 吗？Is the SQL uploaded?
不会，格式化完全在浏览器本地完成。No, formatting runs entirely in the browser.
