usable-xlsm

This module is a Windows Excel COM automation worker that can open an attacker-controlled workbook, inject/overwrite VBA module source code, and execute attacker-supplied macros (and optionally persist changes). It does not contain obvious network exfiltration or direct malware payload code in Python, but it provides a high-risk execution primitive that could be used for sabotage or data theft via VBA. Treat as security-sensitive and ensure strict input validation and controlled usage/sandboxing.
