About:
MassReplaceIt is a powerful find and replace utility for macOS that operates on local files and folders. It supports advanced features like regular expressions, case-insensitive matching, and recursive directory processing. The tool provides immediate previews of changes before execution, ensuring safe and accurate batch modifications.
Key Features:
  • Regular expression (regex) support for complex pattern matching
  • Recursive search within folders and subdirectories
  • Live preview of all changes before applying them
  • Case-insensitive and whole-word matching options
  • Undo functionality for safety
Use Cases:
  • Batch renaming files or cleaning up codebases
  • Updating configuration files across multiple projects
  • Fixing typos or outdated URLs in documentation
Alternatives:
  • sed – Command-line stream editor, more powerful for automation but lacks GUI and previews
  • TextMate – Full-featured editor with find-in-files, but heavier and more complex for simple replacements
