Find and replace

Find and replace is one of the most useful text operations, but many simple editors lack advanced options. This tool supports plain text, case-insensitive and whole-word matching, and full regular expressions with capture groups, so you can do bulk edits on lists, logs, CSV exports or code snippets in seconds.

How to use it

1. Paste your text.
2. Enter what to find and what to replace it with.
3. Choose options: match case, whole word or regular expression.
4. Review the result and copy it.

Examples

• Whole word: replacing cat with dog as a whole word changes cat but leaves category alone.
• Regex reformat dates: find (\d{2})/(\d{2})/(\d{4}) and replace with $3-$2-$1 to turn 27/10/2026 into 2026-10-27.
• Collapse spaces: find \s{2,} and replace with a single space.
• Swap names: find (\w+), (\w+) and replace with $2 $1 to turn Smith, Anna into Anna Smith.

Regex tips

• Special characters such as . * + ? ( ) [ ] { } | ^ $ must be escaped with a backslash to match them literally.
• $1, $2 refer to capture groups in the replacement; $& inserts the whole match.
• Patterns are JavaScript regular expressions, so syntax matches what you would use in JS code.
• Test on a small sample first; a greedy .* often matches more than intended.
