Find and Replace
Find and replace text across a pasted block, with full regex support for pattern-based matching rather than just plain literal text — computed instantly and locally.
A basic find-and-replace handles simple cases fine, but falls short the moment you need to match a pattern rather than an exact string — replacing every phone number in a document, standardizing inconsistent date formats, or removing all instances of a symbol that appears in multiple different contexts. This tool supports both simple text replacement and full regex-powered matching in the same interface.
Paste your text, enter what you’re searching for, and enter the replacement. Toggle case-sensitivity, whole-word-only matching, and regex mode depending on what precision you need. With regex enabled, use capture groups in your replacement (like $1) to reuse matched portions of text in the output. Preview matches highlighted in the original text before committing to the replacement, so you can confirm the pattern is catching exactly what you intend and nothing extra.
Frequently asked questions
Do I need to know regex to use this tool at all?
No — plain text find-and-replace works without regex mode enabled at all, and covers the majority of everyday use cases; regex is there as an option for when you specifically need pattern-based matching rather than an exact string match.
Can I preview what will be replaced before it actually happens?
Yes, matches are highlighted directly in the input text as you type your search pattern, so you can verify the matches are correct before applying the replacement.
How do capture groups work in the replacement field?
When regex mode is on and your pattern includes groups in parentheses, you can reference each captured group in the replacement text using $1, $2, and so on — useful for reformatting matched text (like swapping a “Last, First” name format to “First Last”) rather than just deleting or substituting it entirely.
I want to build and test the regex pattern itself more thoroughly before using it here — is there a better tool for that?
Yes, the Regex tester is purpose-built for iterating on a pattern with live match highlighting and capture group breakdowns — build and confirm your pattern there, then bring it here to actually apply the replacement across your text.
