文本查找替换

功能说明What It Does

文本查找替换工具按查找内容(普通文本或正则表达式)匹配并批量替换整段文本。支持忽略大小写、全词匹配,正则模式可配合 () 分组与 $1、$2 等反向引用。

This tool matches text by a find pattern (literal or regex) and bulk-replaces across the whole input. Case-insensitivity and whole-word matching are supported; regex mode allows () groups and $1, $2 backreferences.

全部在浏览器本地完成,数据不会上传。

正则与反向引用Regex & backreferences

勾选「正则」后,查找内容按正则解析。例如 (\d{4})-(\d{2})-(\d{2}) 可匹配 2026-08-01,替换为 $1/$2/$3 得 2026/08/01。普通文本模式会自动转义特殊字符,避免误匹配。

With "regex" enabled, the find field is parsed as a regular expression. E.g. (\d{4})-(\d{2})-(\d{2}) matches 2026-08-01 and replacing with $1/$2/$3 gives 2026/08/01. Literal mode auto-escapes special characters to avoid false matches.

2. 按需开启正则、忽略大小写或全词匹配。Enable regex, ignore-case or whole-word as needed.
