What is Batch RegEx?

Batch RegEx is a free open-source Windows program designed for searching and replacing text in multiple files using regular expressions (regex). It has a simple interface that allows you to:

• Open multiple text-based files such as code, logs, CSVs etc.
• Write regex patterns to find text matches across all open files
• Replace or remove the matched text with a new string
• Undo changes and save files after editing

Some key features of Batch RegEx:

• Supports literal text and complex regex search patterns
• Replace text via regex groups, templates or static text
• Preview changes before applying to files
• Undo any changes instantly
• Lightweight and portable app with no install required

Batch RegEx is useful for programmers, web developers and IT professionals who need to perform search/replace operations across multiple files. Common uses include cleaning file names, formatting code, modifying CSVs and processing log or text-based data files. The regex support makes complex multi-file find/replace easy.
