Find and Replace Text — Free Online Tool with Regex Support

Find and Replace Text — Bulk Edit Any String with Confidence

Search and replace text inside a block of content with live preview, a real-time match count, and optional regular expression mode. Whether you’re correcting a typo across an article, renaming a variable in code, or applying complex regex transformations, this tool handles it — all client-side, with nothing uploaded.

Modes

• Plain text: the default — special regex characters like ., *, ?, $ are treated literally
• Whole word only: match the term only when surrounded by non-word characters (so “cat” won’t match inside “category”)
• Regular expression: full JavaScript regex syntax — capture groups, lookarounds, quantifiers, character classes
• Multiline (m flag): ^ and $ match line breaks, not just the start and end of the entire text
• Dot matches newlines (s flag): makes the . wildcard span line breaks too

Live feedback

• Type and see the result update immediately
• The match count appears next to “Result” — e.g. “(3 replacements)”
• Invalid regex shows a clear error message so you can fix it

Common uses

• Fix a typo or rename a term throughout a long document
• Convert American spellings to British (or vice versa) by chaining searches
• Strip phone numbers, emails or other patterns with regex
• Normalize whitespace, line endings, or formatting
• Rename variables across a code snippet
• Apply complex transformations to CSV or log data

Regex quick reference

• . any character (except newline, unless dotAll is on)
• \d digit, \w word char, \s whitespace
• [abc] character class, [^abc] negation
• * 0+, + 1+, ? 0 or 1, {n,m} range
• (group) capture, then reference in replacement with $1, $2…
