## Which one, for what

### Grist (D)

Good for: Teams that want a relational spreadsheet with Python formulas and per-document OAuth grants for an agent, or that need to self-host.

Ahead on:
- Payments & pricing, 30 against 15
- Maintenance & community, 78 against 53

Also in its favour:
- Open source

Watch for: No status page was found. status.getgrist.com redirects to a signup form, and the site footer and help centre link to none

### Microsoft Excel (Microsoft Graph workbook API) (C)

Good for: Agents working on .xlsx files that already live in a Microsoft 365 tenant, and for using Excel's calculation engine through function endpoints.

Ahead on:
- Reliability, 62 against 39
- Schema & documentation, 85 against 63
- Agent ergonomics, 73 against 57
- Transparency & trust, 75 against 61

Watch for: Reference pages list delegated permissions only and mark application permissions as not supported

## Verdicts

**Grist.** OAuth tokens carry seven scopes, can be limited to chosen documents and expire after an hour, and the REST API has a public OpenAPI file with an add-or-update call. No status page, SLA terms, DPA or security.txt was found, and the docs say the hosted service has no SOC 2 or ISO 27001 audit.

**Microsoft Excel (Microsoft Graph workbook API).** Ranges, tables, charts and 366 worksheet function endpoints are reachable over REST with a public OpenAPI, and a non-persistent session lets an agent test changes without saving them. The reference pages list delegated permissions only, with Files.ReadWrite as the least privileged scope, and writes take no idempotency key.

## Before you call either

### Grist

1. Connect through OAuth, not an API key. Ask for `doc:read` alone for reading, and have the user pick Selected resources on the consent screen
2. Keep `doc.schema:write` off unless needed. The docs say formula editing lets its holder read any data in the document whatever the access rules
3. Send requests for one document one at a time. The eleventh concurrent request gets 429, and no Retry-After header is documented
4. Use `PUT /api/docs/{docId}/tables/{tableId}/records` with `require` to add or update by key, so a retried write doesn't create a duplicate row
5. Use the `/records` endpoints, not the deprecated `/data` ones, and split large writes to stay under the 1 MB body limit

### Microsoft Excel (Microsoft Graph workbook API)

1. Create a session with POST /workbook/createSession and send `workbook-session-id` on every call. Persistent sessions expire after about 5 minutes idle
2. Set `persistChanges` to false when you only need a calculation or a chart image, so nothing is saved to the file
3. Send one request at a time per workbook and wait for each response. Microsoft warns that parallel writes cause throttling, timeouts and merge conflicts
4. Add rows in one call with a two-dimensional `values` array, and check the table before repeating a row add that returned 504
5. Read bounded addresses such as A1:D500. A whole-column range such as C:C returns null for values, and writes to it are refused
