Find and Replace
Paste your text, enter a search string and a replacement string, and get the result instantly. Toggles let you control case sensitivity, switch between plain-text and regex mode, and choose between replacing the first match only or all matches.
Regex mode supports the full JavaScript regular expression syntax — capture groups, lookaheads, character classes, and quantifiers all work. In the replacement string, use $1, $2, etc. to reference capture groups. The tool shows how many replacements were made so you can verify the result.
Everything runs in your browser — your text is never sent anywhere.

Frequently asked questions
How do I use regex capture groups in the replacement?▼
Enable regex mode, then use parentheses in the search pattern to create capture groups. In the replacement string, $1 refers to the first group, $2 to the second, and so on. For example, search for '(\w+), (\w+)' and replace with '$2 $1' to swap 'Last, First' to 'First Last'.
What happens if my regex is invalid?▼
The tool catches regex syntax errors and shows an error message instead of crashing. Fix the regex pattern and the output updates automatically.
Can I replace with nothing (delete matches)?▼
Yes — leave the replacement field empty to delete all occurrences of the search pattern. This effectively strips the matched text from the input.
