# Microsoft Excel

Give agents tools to find and create workbooks, read and update ranges, and manage worksheets, tables, and charts in Microsoft Excel through Mastra Connect. Each tool call goes through the Mastra platform, which adds the connection's credential. Your application never stores Microsoft Excel credentials.

## Connect

Before you start, complete the [Connect setup](https://mastra.ai/docs/mastra-platform/connect) to install `@mastra/connect` and configure your platform project.

> **Note:** Workbook operations, such as worksheets, ranges, tables, charts, and named items, require a work or school account. Personal Microsoft accounts can find, create, list, get, and delete workbook files, but Microsoft Graph rejects workbook operations on personal OneDrive.

### Connect an account

Run this command from the directory that contains your `.env` file:

```bash
mastra connect add microsoft-excel
```

The CLI guides you through Microsoft Excel's authorization and waits until the connection is active.

### Add tools to an agent

Pass [`tools()`](https://mastra.ai/reference/connect/tools) to the agent and select the `microsoft-excel` provider:

```typescript
import { Agent } from '@mastra/core/agent'
import { tools } from '@mastra/connect'

export const microsoftExcelAgent = new Agent({
  id: 'microsoft-excel-agent',
  name: 'Microsoft Excel agent',
  instructions:
    'You help people find and create workbooks, read and update ranges, and manage worksheets, tables, and charts in Microsoft Excel.',
  model: 'openai/gpt-6-luna',
  tools: tools({ providers: ['microsoft-excel'] }),
})
```

The agent gets 27 Microsoft Excel tools, with keys such as `microsoft_excel_add_chart`. See [Microsoft Excel tools](https://mastra.ai/reference/connect/providers) for the full list, and the [`tools()` parameters](https://mastra.ai/reference/connect/tools) to restrict tools or require approval before a call runs.
