Excel

A Python wrapper around openpyxl that gives you command-line control over Excel files. You can read, write, and edit cells, manage sheets, apply formatting (bold, colors, borders, alignment), merge cells, freeze panes, and export to CSV, JSON, or Markdown. The formatting options are actually pretty thorough: you get named colors, hex codes, font sizes, wrapping, and different border styles. It's built for scripting Excel tasks without opening the application, which is useful for report generation, data transformation pipelines, or batch updates. The commands are straightforward bash calls, so you can chain them in scripts. If you're doing anything with Excel programmatically, this covers the common cases without much ceremony.
