This appears to be a disclosed Microsoft Excel API helper skill that uses a Maton API key and does not show evidence of hidden or unrelated behavior.
Before installing, confirm you trust Maton to proxy Microsoft Excel access, provide MATON_API_KEY only in an environment you control, and approve write or delete actions only after checking the target workbook, worksheet, and intended change.
