Microsoft Excel API integration with managed OAuth. Read and write Excel workbooks, worksheets, ranges, tables, and charts stored in OneDrive. Use this skill when users want to read or modify Excel spreadsheets, manage worksheet data, work with tables, or access cell values. For other third party apps, use the api-gateway skill (https://clawhub.ai/byungkyu/api-gateway). Calls run through the `maton` CLI with OAuth login; default to read and list calls, and confirm every write or new connection with the user.
CLI-first rewrite with the Maton SDK examples; clarify that the CLI and SDKs keep separate credential stores, and reword webhook egress warnings
