A full-featured CLI for automating Excel on Windows with 50+ commands covering everything from basic range operations to Power Query, DAX measures, and pivot tables. The batch mode is the standout feature here: when you need to execute 10+ operations, you can send them all in one process launch instead of spawning Excel repeatedly. It's token-efficient by design, which matters for coding agents hitting context limits. The workflow is COM-based so it only works on Windows, but if you're already in that environment and need scriptable Excel for CI/CD pipelines or scheduled jobs, this beats opening the GUI or wrestling with openpyxl's limitations on complex workbooks.
