/install microsoft-excel
Description
Microsoft Excel API integration with managed OAuth. Read and write Excel workbooks, worksheets, ranges, tables, and charts stored in OneDrive. Use this skill...
Usage Guidance
Install this only if you trust Maton and intend to let an agent access Excel workbooks through the connected Microsoft account. Protect MATON_API_KEY like a password, use the Maton-Connection header when you have multiple accounts, and approve writes only after checking the exact workbook, worksheet, range, or file upload target.
Capability Analysis
Type: OpenClaw Skill
Name: microsoft-excel
Version: 1.0.4
The microsoft-excel skill bundle provides a standard integration for interacting with Microsoft Excel via the Maton API proxy (api.maton.ai). The SKILL.md file contains well-documented instructions and Python examples using urllib to perform REST operations on workbooks and worksheets. It includes explicit safety instructions for the AI agent to seek user approval for write operations and correctly handles authentication via the MATON_API_KEY environment variable without any signs of malicious intent or obfuscation.
Capability Assessment
Purpose & Capability
The documented capabilities match the stated Excel purpose: reading and writing workbooks, worksheets, ranges, tables, and charts through Maton's Microsoft Graph proxy. It also documents OneDrive drive-info, root listing, search, and .xlsx upload endpoints, which are coherent for locating or creating Excel workbooks but should be understood as broader file-discovery capability.
Instruction Scope
The skill clearly requires explicit user approval before create, update, or delete operations and tells users to select a specific Maton connection when multiple accounts exist. The security summary is narrower than the full API reference because it does not explicitly call out drive-level file listing and upload, but those endpoints are documented rather than hidden.
Install Mechanism
The artifact is a single non-executable SKILL.md file with no install scripts, bundled code, package dependencies, or automatic setup behavior.
Credentials
Network access, managed OAuth, and MATON_API_KEY are proportionate for a Microsoft Excel API integration. The key should be treated as sensitive because it authorizes requests through Maton's API proxy to the connected Microsoft account.
Persistence & Privilege
Persistent OAuth connections and workbook sessions are disclosed and purpose-aligned. Connection deletion is documented, workbook sessions are temporary, and no local persistence or privilege escalation behavior is present in the artifact.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install microsoft-excel - After installation, invoke the skill by name or use
/microsoft-excel - Provide required inputs per the skill's parameter spec and get structured output
