Find and Replace Text Online

Bulk text edits — renaming a product across a document, swapping a domain in a list of URLs, stripping a repeated prefix — are trivial with find and replace and painful without it. This tool supports plain text, whole-word, and full regular expression modes, and reports how many replacements were made.

How to use it

  1. Paste your text into the input box.
  2. Enter what to find and what to replace it with.
  3. Toggle case sensitivity, whole-word matching, or regex mode as needed.
  4. Check the replacement count, then copy the result.

Frequently asked questions

What does whole-word matching do?

It stops partial matches. Replacing "cat" without it would also alter "category" and "concatenate"; with it enabled, only the standalone word is changed.

How do I use capture groups?

Enable regex mode, wrap part of your pattern in parentheses, and reference it in the replacement as $1, $2 and so on. Swapping "Last, First" to "First Last" is a one-line job.

Why does my regex not match anything?

Usually an unescaped special character. Dots, question marks, brackets, and plus signs all have meaning in a regex; escape them with a backslash to match them literally.

Is my text sent anywhere?

No. Everything runs in your browser, so confidential documents never leave your device.
