操作方法

  1. 打开Excel
  2. 添加开发者工具, 并打开 Visual Basic
  3. 添加模块
  4. 复制以下代码
  5. Excel 另存为支持宏的(*.xlsm)格式
  6. 愉快的使用正则函数吧

函数说明

函数参数说明参数说明参数说明参数说明参数说明
Regex_IsMatchDataRange数据矩阵pattern正则表达式IsIgnoreCase是否忽略大小写
Regex_ReplaceStringDataRange数据矩阵pattern正则表达式replace替换正则IsIgnoreCase是否忽略大小写

例子

Regex_IsMatch

匹配多行

=Regex_IsMatch(B13:B14,“(a.+?)b”,FALSE)

匹配多列

=Regex_IsMatch($B 1 : 1: 1:C$1,“(a.+?)b”,FALSE)

匹配多行多列

=Regex_IsMatch($B 20 : 20: 20:C$21,“(a.+?)b”,FALSE)

Regex_MatchString

匹配多行

=Regex_MatchString($B 13 : 13: 13:B$14,“a.+?b”,FALSE,2)

匹配多列

=Regex_MatchString($B 1 : 1: 1:C$1,“a.+?b”,FALSE,3)

匹配多行多列

=Regex_MatchString($B 20 : 20: 20:C$21,“a.+?b”,FALSE,2)

Regex_ReplaceString

=Regex_ReplaceString($B 20 : 20: 20:C$21,“(a.+?)b”,“$1”,FALSE)

Regex_MatchStringGroup

只能匹配单元格

=Regex_MatchStringGroup(B27,“(.+)_(.+)”,FALSE,0,0)
