# Using Excel with Marrow MCP
# Using Excel with Marrow MCP
This guide shows how to use **Marrow MCP** in **Microsoft Excel** through the Claude add-in, so you can query your Amazon data without leaving your spreadsheet.
> **Before you start**: This guide assumes you have already connected Marrow MCP to Claude. If you have not done that yet, see [Using Claude](/hologrow-marrow-mcp/claude) first.
## Set up the Claude add-in for Microsoft 365
* Follow the steps in the [Claude for Microsoft 365 documentation](https://claude.com/claude-for-microsoft-365) to install the Claude add-in and sign in with your Microsoft account.
* After the add-in is installed, it appears in the Excel ribbon. You can open it from any workbook.
## Start a conversation in Excel
1. Open a workbook in Excel.
2. Click the **Claude** icon in the ribbon to open the Claude side panel.
3. Make sure Marrow is listed as an active connector in the Claude panel. If it is missing, re-add it following the [Using Claude](/hologrow-marrow-mcp/claude) guide.
4. Enter your prompt in the chat input and press Enter.
> **Note**: In a new conversation, Claude may not immediately see the Marrow connector. If that happens, ask Claude to refresh connectors.
