# How to connect Microsoft Excel to OpenClaw (no API keys) > Connect Microsoft Excel to OpenClaw with ClawLink in one click — 54 tools your AI agent can call from chat via hosted OAuth. No API keys, no manual setup. Web version: https://claw-link.dev/openclaw/microsoft-excel The usual route to Microsoft Excel access for OpenClaw is an MCP server you configure and keep running, plus your own OAuth app or API keys. ClawLink gives OpenClaw a more practical Microsoft Excel setup: install one ClawHub skill, connect Microsoft Excel in the browser, and OpenClaw can call real Microsoft Excel actions from any chat surface with no auth, token refresh, or tool wiring to build yourself. **Start here:** install the ClawLink plugin (`openclaw plugins install clawhub:clawlink-plugin`), pair it in the browser, then connect the app in the ClawLink dashboard. The interactive install prompt is on the web version of this page: https://claw-link.dev/openclaw/microsoft-excel ## Setup It takes three steps to connect OpenClaw to Microsoft Excel. 1. **Install ClawLink** — add the plugin to OpenClaw once. 2. **Connect Microsoft Excel** — one-click OAuth in the ClawLink dashboard. 3. **Use it from chat** — ask OpenClaw in plain English. **Alternative for any agent (no plugin needed):** if the OpenClaw plugin route isn't available or doesn't work, any AI agent with shell access can use the ClawLink CLI instead: ```bash npx -y @useclawlink/cli login # sign in via browser — no API key to paste npx -y @useclawlink/cli connect microsoft-excel # connect Microsoft Excel (browser OAuth) npx -y @useclawlink/cli actions microsoft-excel # list available actions npx -y @useclawlink/cli run microsoft-excel --input '' # execute (add --confirm for writes) ``` ### Install by command The setup prompt above does all of this in one paste. By hand, it is one install command plus a browser approval: ```bash openclaw plugins install clawhub:clawlink-plugin ``` Then ask OpenClaw to set up ClawLink. It starts browser pairing and prints an approval link — open it, approve the device, return to the chat, and say `done`. Finally, connect Microsoft Excel in the [ClawLink dashboard](https://claw-link.dev/dashboard) — a one-click OAuth approval, no API keys. Verify the connection by asking OpenClaw: > Use Microsoft Excel to excel add chart and walk me through the result in plain English. ### Using a different agent? The OpenClaw plugin is one client of ClawLink's MCP server. Claude Code, Cursor, Codex, or any agent that can run a shell command pairs with the same ClawLink account through the CLI: ```bash npx -y @useclawlink/cli login ``` `login` opens the same browser approval and stores a credential locally. Once Microsoft Excel is connected in the dashboard, that agent calls the same 54 Microsoft Excel tools over MCP. Full setup for MCP clients and shell agents: [connect apps to any AI agent](https://claw-link.dev/learn/connect-apps-to-any-ai-agent). ## Microsoft Excel MCP for OpenClaw Looking for a Microsoft Excel MCP server for OpenClaw? ClawLink connects Microsoft Excel to OpenClaw and exposes 54 Microsoft Excel tools your agent can call over [MCP](https://claw-link.dev/learn/what-is-an-mcp-server), with [hosted auth](https://claw-link.dev/learn/oauth-for-ai-agents) and nothing to run or maintain yourself. Using Hermes instead? The [Hermes Microsoft Excel integration](https://claw-link.dev/hermes/microsoft-excel) works the same way. ## What the OpenClaw Microsoft Excel integration can do 54 Microsoft Excel tools are ready for OpenClaw once the account is connected.

That is fine if you want to build and maintain the integration yourself. Most teams just want Microsoft Excel working from chat. | | Manual | ClawLink | |---|---|---| | **Connection flow** | Register a Microsoft Excel app, configure redirect URLs, manage consent details, and reconnect users when auth settings drift. | Users connect Microsoft Excel through the hosted browser flow and ClawLink keeps the token lifecycle out of your app code. | | **Ongoing maintenance** | You own refresh logic, permission debugging, environment config, and every provider-specific edge case for Microsoft Excel. | ClawLink handles the repetitive integration plumbing so your team can focus on the workflow instead of the infrastructure. | | **Agent usability** | You still need to expose the right Microsoft Excel actions to the runtime in a format your agent can reliably use. | 54 tools for Microsoft Excel are already exposed through ClawLink, so the agent can read and act from chat immediately. | ## ClawLink vs. Composio Composio also exposes Microsoft Excel to AI agents. It is developer infrastructure: Python and TypeScript SDKs, an MCP server, and a catalog past 1,000 apps, aimed at teams shipping agent products. ClawLink is built for OpenClaw users instead. You install the plugin once, connect Microsoft Excel in the browser, and the 54 tools above work from chat. There is no SDK, no config file, and no API key handling. Choosing between them?

Make sure Microsoft Excel is connected in the dashboard, then start a fresh chat so OpenClaw reloads the tool catalog. If OpenClaw runs as a persistent gateway, restart it so the new tools register. ### Connection succeeds but no tools appear Reconnect Microsoft Excel from the dashboard, then start a fresh chat if the runtime still has the old tool catalog loaded. ### "Tool schema not loaded yet" error when calling Microsoft Excel tools Microsoft Excel tool schemas load on demand the first time a tool runs and are cached after that, so this error usually clears on its own: wait a few seconds and retry the same request. If every Microsoft Excel call keeps failing with it in a fresh chat, reconnect from the dashboard, and contact support if it still persists — that pattern points to a configuration problem on our side, not something you can fix by reconnecting again. ### Microsoft Excel returns 403 or "permission denied" on one action while others work Two usual causes. The connected account may not have access to the specific workspace, inbox, store, or project in the request — check that first. If access looks right, the agent may have sent a placeholder value (like "YOUR_ID" or an example id from documentation) instead of a real one: ask it to run a list or search tool first, then retry the action with a real id from those results. Most failures at this stage are one of these two, not ClawLink bugs. ### OAuth finished in the browser but the account is still missing Try reconnecting Microsoft Excel and complete the consent flow in the same browser session. Partial OAuth approvals or switching accounts mid-flow can leave the connection incomplete. ### Is there a OpenClaw Microsoft Excel integration? Yes. ClawLink is the fastest way to connect OpenClaw to Microsoft Excel: link your Microsoft Excel account once in the browser and OpenClaw can call the Microsoft Excel API through 54 ready-made tools — no custom code or token handling. ### How do I add Microsoft Excel to OpenClaw with ClawLink? Paste the setup prompt from this page into OpenClaw. It installs the ClawLink Microsoft Excel skill from ClawHub, then you click Connect in the dashboard to authorize Microsoft Excel. OpenClaw calls the tools from the next message — no config files or API keys to manage. ### How long does it take to connect Microsoft Excel to OpenClaw? About two minutes. Sign in, click Connect next to Microsoft Excel in the dashboard, authenticate, and OpenClaw can use it from the next chat message. ### Why use ClawLink instead of wiring Microsoft Excel up myself? The alternative to ClawLink is usually manual OAuth app setup plus your own token handling, permission troubleshooting, and tool plumbing for OpenClaw. That is fine if you want to build and maintain the integration yourself. Most teams just want Microsoft Excel working from chat. ### OpenClaw installed the Microsoft Excel skill but can't call the tools The ClawHub skill teaches OpenClaw about Microsoft Excel, but the calls run through the ClawLink plugin and your connected account.
