PowerGREP is a powerful tool for quickly searching through text and binary files. It also performs complex text and binary replacement operations for easy maintenance of data, web sites, software source code, reports, etc. PowerGREP can search for plain text, or use powerful Perl-compatible regular expressions. It is truly amazing.
If you work with data—numeric, textual, or binary, whether structured or unstructured—then PowerGREP should be a key weapon in your arsenal. Its capabilities are perhaps unrivaled by any other application which implements regular expressions to search, replace, and/or extract data. It can target thousands of files with ease, and supports creating backups of the files it modifies. It works with several of the most common document formats such as Excel, Word, and PDF. Additionally, ZIP, RAR, 7z, and many more archive format can have their contents processed or ignored. PowerGREP can even perform file renaming. This software tool is kinda sorta mind-blowing.
