Find and Replace Text

Find and replace text online

Paste text, type a search term and a replacement, and the output updates live as you type. Three optional modes extend the basic search: Ignore case matches regardless of capitalisation, Whole word skips partial matches inside longer words, and Regex lets you write a full regular expression for advanced patterns. A counter shows how many replacements were made. Nothing is uploaded — everything runs locally in your browser.

Leave the replacement field blank to delete all matches. The tool escapes special characters automatically in plain-text mode, so a literal dot or plus sign is matched as-is. Switch to Regex mode only when you need pattern matching such as \d+ to match numbers or \s+ to match any whitespace.

FAQ

What does Whole word mode do? It adds word boundaries around your search term so that, for example, searching for "cat" will not match "concatenate" — only standalone occurrences of the word are replaced.

Why did Regex mode show an error? Your pattern contains invalid regular expression syntax. Common mistakes include an unclosed bracket [ or a dangling backslash. Switch Regex mode off to search for the text literally, or correct the pattern.

Is my text sent anywhere? No. All find-and-replace logic runs client-side; your text never leaves your browser.
