    Business, SharePoint, or a group drive via Microsoft Graph. Supports

    worksheet, table, chart, range, and named-item operations on .xlsx

    workbooks. All requests require an OAuth 2.0 bearer token from the

    Microsoft identity platform; use Files.Read for read operations and

    Files.ReadWrite for write operations. Optional workbook-session-id

    header enables persistent or non-persistent session modes.
