About SharePoint Excel 365
The shared workbooks your team plans the year in.
SharePoint Excel 365 is shorthand for one specific corner of Microsoft 365: the .xlsx files that live in a SharePoint site's document library, opened from the team channel rather than from somebody's personal OneDrive. The connector reads them through the Microsoft Graph workbook API, addressing the file as /sites/{site-id}/drive/root:/Finance/Budget%202026.xlsx:/workbook and pulling the worksheets, tables, named ranges and ranges your team curates inside it. Auth runs through Microsoft Entra with Sites.Read.All and Files.Read.All at the application tier, or the matching delegated scopes when a user signs in.
Operationally, the SharePoint variant matters because that is where the workbooks the rest of the company depends on quietly accumulate. The annual budget gets built once, dropped in Finance/Budgets/, and re-edited by three controllers for the next eleven months. The vendor register lives in Procurement/Vendors with macros nobody dares to touch. The KPI intake template is duplicated per branch and uploaded back to the same document library every month-end. Pulling those workbooks into the warehouse lets the rows sit beside Business Central postings, Exact invoices and Salesforce opportunities, so the numbers in the workbook can be checked, joined and historised instead of trusted on the strength of the last person who saved the file.
