Overview

Excel via OneDrive 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 via OneDrive connector is fully managed: it extracts data from Excel via OneDrive, 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

It can reach Excel via OneDrive.
