About regex mode

Regex mode uses JavaScript regular expressions with the multiline flag on, so ^ and $ match at the start and end of each line. Groups in parentheses are available as $1, $2…, named groups as $<name>, and $& is the whole match. In plain mode every character is literal, including $.

Cleaning up pasted text? The smart quotes converter fixes quotes and dashes, and the invisible character detector finds characters you can’t search for because you can’t see them.

Frequently asked questions

About the find & replace (with regex).

Leave “Use \n and \t” switched on and type \n for a line break or \t for a tab in either box. For example, find \n\n and replace with \n to remove blank lines between paragraphs, or find \n and replace with a comma and space to turn a list into one line.

It only matches the search term when it stands alone, not inside a longer word. Replacing “cat” with whole word on changes “cat” but leaves “category” and “concatenate” alone. It understands letters in any language, not just A–Z.

Switch on Regex to use JavaScript regular expressions. Parentheses capture groups you can reuse in the replacement as $1, $2 and so on, and $& inserts the whole match. Example: find (\w+)@(\w+)\.com and replace with $1 at $2 to rewrite email addresses. Invalid patterns show an error instead of failing silently.
