How to use this tool

  4. Click Replace all and copy the result.

About this tool

This is the find-and-replace from your editor, available anywhere: paste text, enter what to find and what to replace it with, and see how many matches exist before committing. Whole-word matching prevents "cat" from changing "category"; regex mode unlocks pattern replacements like normalizing dates or stripping prefixes, with clear errors when a pattern is invalid.

Frequently asked questions

How do I avoid replacing partial words?
Enable "whole words only". Then replacing "art" won't touch "start" or "artist" — only standalone occurrences of "art".
Can I use regular expressions?
Yes. Switch on regex mode to use JavaScript regular expressions, including capture groups referenced as $1, $2 in the replacement.
Can I preview how many changes will happen?
The live match counter shows exactly how many occurrences the current settings find before you click Replace.
