FAQ
Can a WorkAist AI agent really automate Excel Online end-to-end?▼
Yes. The connector exposes read and write tools through Model Context Protocol. AI agents call them through plain-language instructions in a CLAUDE.md file — no glue code.
How does this differ from using the Excel Online API directly?▼
The connector adds permission isolation, audit logging, cost tracking per agent, and reversible PII redaction at the LLM boundary. It also presents Excel Online as part of a unified Knowledge Graph alongside your other tools.
What does it cost?▼
WorkAist is open-source under AGPL-3.0 and self-hosted, so the connector itself is free. You pay only for Excel Online's own API costs (if any) and the LLM tokens your agent consumes.
Is my Excel Online data sent to a third party?▼
No. WorkAist runs in your own infrastructure. Data flows from Excel Online → your WorkAist instance → the LLM you choose. Sensitive fields can be tokenized before reaching the LLM.
What if Excel Online changes its API?▼
The connector is versioned and published openly. When Excel Online ships breaking changes, we bump the connector version and the marketplace UI surfaces the upgrade as a one-click apply.
