An internal AI assistant can use information from Excel, but simply connecting a workbook does not make it a dependable live business database. Text-heavy workbooks may function as searchable documents. Exact questions about rows, totals, dates, inventory, pricing or status usually require a structured connection, SharePoint List, Dataverse table or controlled workflow.
Why Excel Creates a Special Problem
Excel may contain both narrative instructions and structured records. Retrieval can often find written explanations, but a row-level query depends on columns, filters, formulas and data quality.
Document Retrieval Is Not Structured Querying
A question such as “What do the notes say?” differs from “Which active technicians in Houston have certifications expiring this quarter?” The second requires exact filtering and business rules.
Better Options
Use a SharePoint List for simple operational records, Dataverse for related tables and security roles, or a controlled flow that queries an Excel table.
Microsoft documents the Excel Online connector in its Excel Online Business connector reference.
Format the Workbook
Use defined tables, clear headings, consistent values and no merged cells or decorative rows inside the data area.
Calculations Need Controlled Rules
Formal totals, forecasts and compliance calculations should use approved reports or business systems. Microsoft’s Power BI guidance explains governed reporting practices.
Where Maisy Fits
The AskMaisy implementation guide explains how structured sources and workflows fit the Knowledge Hub. The Pixeldust process determines whether spreadsheet information should remain in Excel, move to a List or be accessed through a controlled action.
The Practical Answer
Excel may contain the answer. The implementation still has to determine how the answer should be retrieved, calculated, secured and verified.
