find_replaceFind & Replace
What is the Find and Replace?
A find-and-replace tool searches a block of text for a pattern (literal or regex) and substitutes every match with a replacement string. Editors have had this for decades; the value of a web tool is that you can paste text from anywhere, see matches highlighted before committing, and not have to open an editor.
How to use the Find and Replace
- 1
Paste your text
Drop the source content into the input pane. Any length works; matches highlight as you type the search.
- 2
Type the find string
Enter what you want to match. Toggle Case sensitive if it matters, or Use regex for pattern syntax.
- 3
Preview the matches
Yellow highlights show every hit, and the match count appears above the preview. Verify before replacing.
- 4
Click Replace All
Type the replacement and click Replace All. The result appears in a new pane below, ready to copy.
Frequently Asked Questions
Does it support regular expressions?
Yes. Toggle Use regex to switch from literal matching to JavaScript regex syntax: character classes (\d, \w, \s), quantifiers (*, +, ?), groups, lookaheads, lookbehinds. The matching engine is the browser's native RegExp, so anything that works in JavaScript works here.
Can I see matches before replacing?
Yes. Yellow highlights mark every match the moment you type into the Find field, and a count appears above the preview pane. You can adjust the search and watch the matches update before committing to Replace All.
Is my text private?
Both the input and the search/replace happen in your browser. Open DevTools, switch to Network, and you'll see no outbound request when you click Replace All. Safe for source code, contracts, or any text you wouldn't want sitting in a third party's logs.
