dnGrep is an Open Source Windows search and replace tool that can be used as a GUI for GREP.

It is geared at making the process of finding files, Regex, XPath, and text in documents easier. Search through text files, Word documents, PDFs, and archives using text, regular expression, XPath, and phonetic queries. dnGrep includes search-and-replace, whole-file preview, right-click search in File Explorer, and much more.

dnGrep is displayed through a straightforward UI that will be familiar to users that have used (or use) GREP. One thing to note is, you can use dnGrep without having GREP installed or use it to provide a GUI to GREP if you do. Either way, it provides a powerful search and replace option.

dnGrep's last stable version was released in 2015 but is still being actively worked on through numerous Beta updates. MajorGeeks download location is for the last stable version.
