Advanced Find and Replace for Text Processing
Our Find and Replace tool goes beyond simple text substitution. With support for regular expressions, case-sensitive matching, whole word search, and batch replacements, you can perform complex text transformations in seconds. Whether you're cleaning data, refactoring code, or editing documents, this tool handles it all with precision.
All processing happens locally in your browser, ensuring complete privacy for sensitive documents. No data is ever sent to servers, and you can work offline after loading the page. Process files up to 50MB with instant results.
Replace Multiple Words Online — on Mobile, Laptop or Tablet
Sometimes you just need to swap one word for another across a long block of text — a name that changed, a date, or a misspelling repeated dozens of times. Doing it by hand is slow and easy to get wrong. This free online find and replace tool changes every match in a single click, and it runs in any browser — desktop, laptop, Android phone, iPhone, or tablet — with nothing to install and no signup.
People use it to replace multiple words at once, fix a repeated typo across a whole document, swap commas for new lines, clean up data before importing into Excel or Google Sheets, or rename variables in code. Turn on Regex for pattern-based replacement, Case for case-sensitive matching, or Whole Word so searching "cat" never touches "category". Because everything runs in your browser, your text stays private on your device and the tool keeps working offline once the page has loaded.
It works fully on mobile: open the page in your phone's browser, paste your text, type the word to find and the word to replace, and tap Replace All — the same experience as on a laptop, with no app to download. A handy alternative when you need find and replace but don't have Microsoft Word or a desktop open.
