Find & Replace (Regex) Tool

Bulk replace with plain text or regular expressions.

Output 0 matches replaced

What is this tool?

Replaces every occurrence of a pattern in your text and reports how many matches were changed. Plain-text mode treats the search string literally; regex mode accepts full JavaScript regular expressions, including capture-group substitutions in the replacement ($1, $2, $&). A case-sensitivity toggle applies to both modes. Everything runs in your browser — nothing is uploaded.

How to use it

  1. Paste your text and enter what to find.
  2. Toggle regex mode for pattern matching, and case sensitivity as needed.
  3. Copy the transformed output; the match count updates live.
