Regex Workbench

Test the pattern, preview every change, then replace

Build and test regular expressions on your own files, then preview find-and-replace before applying it.

What it does

Regex Workbench is planned to make regular expressions safer to use on real files. Write a pattern and see matches highlighted in sample text, with a plain-language explanation of each part. Then run find-and-replace across a folder with a full preview of every change, apply only what you approve, and keep a backup of each changed file.
