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, or over raw HTTP with a Maton API key where the CLI cannot be installed. Every call is authenticated as the user's connection and reaches only what that connection's authorization allows, which the provider enforces on every request; the endpoints documented here are the ones this skill uses, and any other endpoint of this app needs the user to ask for it by name. Default to read and list calls, and confirm every write or new connection with the user. This file also documents the three constructs that turn a Microsoft Excel connection into automation, in the order they are used: the connection (the first step), a hosted function that runs a Microsoft Excel action through the Maton SDK, and a trigger that calls that function on a schedule or on an event. Those sections are the platform's own reference text, shared with the api-gateway skill, with Microsoft Excel examples; they add no Microsoft Excel capability - Microsoft Excel is not an event source, a trigger cannot read Microsoft Excel data, and the files under `references/<source>/triggers.md` are the platform's event catalogues for the sources Maton offers (time, Calendly, GitHub, Gmail, HubSpot, Linear, Notion, Slack, Stripe).

Install this only if you want Maton to access Excel data in your Microsoft account. Before using it, confirm the account and scopes, approve every write or automation separately, keep trigger scopes narrow, and only use the non-Excel trigger references when you intentionally want cross-app automation with a named source and destination.
