ClawLink connects Hermes Agent to Microsoft Excel in one click with hosted OAuth, no manual app setup, and 12 tools your agent can call from chat.
ClawLink gives Hermes Agent a more practical Microsoft Excel setup than rolling your own integration. Instead of building auth, token refresh, and tool wiring yourself, you connect once and start using real Microsoft Excel actions from chat.

That is fine if you want to build and maintain the integration yourself. Most teams just want Microsoft Excel working from chat.
Connection flow

Register a Microsoft Excel app, configure redirect URLs, manage consent details, and reconnect users when auth settings drift.

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.

Connect microsoft-excel through ClawLink's hosted Composio setup.
Microsoft Excel uses hosted oauth, so users connect once in the browser and ClawLink handles the token lifecycle after that.
Hermes Agent works best when the request is concrete. Ask for a specific outcome in Microsoft Excel instead of a vague "check this" instruction.
Reconnect Microsoft Excel from the dashboard, then start a fresh chat if the runtime still has the old tool catalog loaded.
Check whether the connected account has access to the workspace, inbox, store, or project you are trying to use. Most failures at this stage are permission mismatches, not ClawLink bugs.
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.
