MassReplaceIt for MAC
Free Mac utility that finds and replaces text in the contents or names of many files at once, with previews, regular expressions and undo.
MassReplaceIt Overview
MassReplaceIt is a find and replace utility for many files at once. You choose the files or folders, type what to look for and what to put in its place, and MassReplaceIt searches either the file contents or the file names, such as changing the extension of hundreds of files in one go. Before anything is written you can preview the changes, and each search gives detailed results. Searches can be saved and used again, filters leave out files you do not want touched, and regular expressions handle patterns that plain text cannot.
MassReplaceIt is made by HexMonkey Software and is free to use; the developer asks for an optional donation. Version 4.0 is the first with Apple Silicon support, and it also refreshes the interface and lets you view folder hierarchies in file lists and organize saved searches into folders. It needs macOS 10.13 or later and runs on Apple Silicon and Intel Macs. For older systems, the developer still offers MassReplaceIt 3.1.2 for Mac OS X 10.7 to 10.12 and 2.9.1 for Mac OS X 10.3 to 10.6. Changes from a previous search can be undone, but as with any tool that rewrites many files, a backup first is a good idea.
