Find and Replace Text

Replace a word, name or phrase everywhere in your text at once — with whole-word, case-sensitive and regex options.

🔒 Runs entirely in your browser — nothing you type is uploaded.

How to use the Find and Replace Text

  1. Paste your text.
  2. Type what to find and what to replace it with.
  3. Copy the result (or click “Use result as new text” to do another replacement).

About this tool

Useful for updating a name in a contract template, fixing a repeated spelling mistake, or changing a date across a long document. “Whole words only” stops “cat” from also changing “category”. In the replacement, type \n for a new line.

With “Regular expression” on you can use patterns — for example \d{10} finds 10-digit phone numbers — and refer to captured groups in the replacement with $1, $2.

Frequently asked questions

How do I replace a word only when it’s a whole word?

Tick “Whole words only”. Then replacing “art” won’t touch “start” or “article”.

Can I replace text with a line break?

Yes — type \n in the “Replace with” box to insert a new line, or \t for a tab.

What does the regular-expression option do?

It treats the “Find” box as a JavaScript regex pattern, so you can match things like any number (\d+) or an email-like pattern, and reuse groups with $1.
