Overview

Excel in your warehouse.
Ready for your agents.

Excel is a spreadsheet program developed by Microsoft that allows users to perform various data analysis and calculation tasks. Weld's Excel connector is fully managed: it extracts data from Excel, loads it into your warehouse, and keeps it in sync. The data lands in a clean, documented schema with agent context attached, so analysts can query it with SQL or dbt, and agents can query it over the Weld MCP server without guessing at tables or joins.

Weld MCP server

Ask your agent.
It can reach Excel.

Connect Claude, Cursor, ChatGPT or your own agent to Weld over MCP. It finds the Excel tables Weld has synced and queries your warehouse.
