Find and Replace Text
Replace every occurrence of a word or pattern across a whole block of text — plain search, whole-word matching, or full regular expressions.
Regular expressions use JavaScript syntax. Capture groups can be referenced in the replacement as $1, $2 and so on — for example finding (\d+)-(\d+) and replacing with $2-$1 swaps the two numbers.
Frequently Asked Questions
How do I delete text instead of replacing it?
Leave the replace field empty. Every match is then removed from the text.
What can I do with regular expressions?
Match patterns rather than fixed text — dates, phone numbers, anything repetitive. Capture groups can be reused in the replacement as $1, $2, so finding (\d+)-(\d+) and replacing with $2-$1 swaps the two numbers everywhere.
What does whole words only do?
It stops partial matches. Searching for 'cat' with the option on will not match 'category' or 'concatenate'. It is disabled in regex mode, where you can use \b yourself.
Why did my regex fail?
Usually an unescaped special character or an unclosed bracket. The error message from the browser regex engine is shown in full, including the position where parsing failed.
