# Find and Replace Text Online: The Complete Guide
Need to swap every instance of "colour" with "color"? Remove a recurring prefix from 200 lines? Or apply a regex transformation across an entire file? FreeToolJet's Find and Replace tool handles all of these in your browser — no text editor required.
Features
- Case-sensitive matching: Only replace "Error" when "error" should stay untouched.
- Whole word matching: Replace "log" without affecting "dialog" or "catalog".
- Regex mode: Use patterns like /d{3}-d{4}/ to find phone numbers, or /(?<=@)w+/ to extract usernames.
- Match count: See how many matches exist before committing to the replacement.
Common Use Cases
- Normalize terminology across documentation.
- Reformat dates, phone numbers, or IDs in bulk.
- Strip HTML tags or Markdown formatting from pasted content.
- Clean up data exports before importing into a spreadsheet.
