XLSXGrep
CLI tool to search text in XLSX and XLS files written in Python3. It works similarly to GNU Grep. It supports search in many XLSX and XLS files at once, even recursively in directories. Xlsxgrep tries to be compatible with GNU Grep, where it makes sense. Some of GNU Grep options are supported (such as `-r`, `-i` or `-c`).
