## What it is
dnGrep is a graphical grep-style search utility for Windows that searches across text files, Word/Excel/PowerPoint documents, PDFs, and archives using text, regex, XPath, and phonetic queries. It includes search-and-replace with undo, whole-file preview, and right-click search from File Explorer.

## Use cases
- search text inside pdfs and word documents on windows
- grep across files with a gui instead of command line
- search inside zip and 7z archives without extracting
- regex search and replace across many files
- find files containing specific text from file explorer right-click
- search excel and powerpoint files for content

## When to choose
- you need powerful multi-format file search on Windows with a friendly UI
- you want grep-like regex search but prefer not to use the terminal
- you need to search inside archives or binary document formats

## When to avoid
- you need a command-line or scriptable grep for automation
- you are on Linux or macOS
- you need to replace text inside binary formats like Word or PDF
