Configuration
5 fields, none required. A dotted path is a nested object and name[] an array of objects — the editor renders the same tree.
| Field | Type | Required | Default | Constraints | Example |
|---|---|---|---|---|---|
drive_id The drive holding the workbook. Leave blank for the connected user's own OneDrive (/me/drive). Ignored when site_id is set. | string | No | — | — | — |
site_id A SharePoint site id when the workbook lives in that site's document library, as 'hostname,siteCollectionId,siteId'. Takes precedence over drive_id. | string | No | — | — | — |
item_id The workbook file's driveItem id, addressing it as /items/{item-id}. Takes precedence over item_path when both are set. | string | No | — | — | — |
item_path The workbook's path inside the drive, e.g. 'Reports/Q3.xlsx', addressing it as /root:/Reports/Q3.xlsx:. Used when item_id is blank. | string | No | — | — | — |
max_results How many tables to return at most; Graph pages are followed until this many. | number | No | 50 | 1–1000 | — |
- At least one of item_id, item_path must be set.

In a technical demo we add the Microsoft Excel connection, drop the node on the canvas and let Workflow Health pre-flight it before the first real run.
