  • Converts automatically when entering text or changing settings.

Useful Regular Expressions

If you are familiar with regular expressions (regex), you can do almost anything without tools. A regular expression is a technology that allows text searches under a variety of conditions.

Incidentally, this tool also uses regular expressions in its programs. For example, “Remove blank lines” is represented by ^\s*?$(\r\n|\r|\n)? is a regular expression. These characters are called meta characters and have an abstract meaning. The regular expression is matched by combining these meta characters.

Metacharacter Meaning
^ Beginning of line
\s*? 0 to n whitespace
$ End of line
(\r\n|\r|\n)? 0 to 1 line feed

I have also written an article on regular expressions, if you would like to read it.
