Find and replace online
Find and replace text online with normal, extended, or regex mode. Match case, whole words, count occurrences, then copy or download.
What is find and replace online?
Find and replace online is a text replacer that searches pasted content for a string or pattern and substitutes a replacement value. Use normal mode for literal text, extended mode for escape sequences, or regex mode for advanced patterns, then review the occurrence count. People also search for search and replace, replace text online, text find and replace, or string replace online; this page serves that intent. It does not edit Word documents or Notepad files directly.

Tips for search and replace
Avoid common replacement mistakes.
- Start in normal mode: Use literal matching first before switching to regex.
- Check the occurrence count: Confirm how many matches exist before copying output.
- Use whole word for terms: Prevent partial replacements inside longer words.
- Try extended for newlines: Search for \n or \t when replacing line or tab characters.
- Validate regex patterns: Invalid regular expressions show an error and leave input unchanged.
