The spreadsheet every agent already knows how to use

SpreadsheetsProductivityAnalyticsFinanceDocuments

Microsoft Excel is the world's most widely deployed spreadsheet, living in every finance team, ops function, and analyst's OneDrive. Connect it to Actionist and your agents can read named ranges, write structured rows, manage worksheets, and react to cell-level changes — turning static workbooks into live data pipelines without a single formula change. From P&L models to inventory trackers to pipeline dashboards, your Excel files become the authoritative record that the rest of your stack syncs to.

Eliminates manual work. Agents eliminate the manual copy-paste between Excel and downstream tools — CRM updates, dashboard refreshes, and report exports that eat 20–45 minutes each now execute in seconds.

Churn signal to action in 60 seconds

When a support email arrives flagging an at-risk account, your agent reads the account's row from the CustomerHealth workbook, updates the ChurnRisk column with today's date and risk level, posts a prioritised alert in Slack with the account value and open issues, and drops a follow-up call on the CSM's calendar — all before the CSM has finished reading the email. No spreadsheet open, no calendar drag-and-drop, no Slack tab-switching.

How to plug Microsoft Excel into Actionist

Pick the connection method that suits your environment.

The fastest path for agents that need to read and write Excel workbooks stored in OneDrive. The Microsoft Excel MCP server handles the OAuth handshake with your Microsoft 365 account — no tokens to manage, no Graph API credentials to rotate.

1
Open the Apps tab

Find Microsoft Excel in the Apps library and click Connect. MCP is selected by default.

2
Sign in with your Microsoft account

A Microsoft 365 sign-in window opens. Log in with the account that owns (or has access to) the OneDrive where your Excel workbooks live, then grant the requested permissions to read and write files.

3
Test the connection

Actionist runs a read-only call to verify the handshake. You're ready.

FAQs

Questions about Microsoft Excel + Actionist

Which Excel files can Actionist access?
Actionist accesses any Excel workbook (.xlsx) stored in the OneDrive or SharePoint of the connected Microsoft 365 account. Files in shared drives are accessible if the connected account has at least read permission. Files stored only on a local hard drive (not synced to OneDrive) are not reachable — make sure the workbooks you want to automate are cloud-synced.
Does the agent work with Excel tables or just plain worksheet rows?
Both. The agent has separate actions for named Excel tables (structured Table objects with headers and typed columns) and plain worksheet rows identified by position. For most automation use cases, named tables are strongly recommended — they give the agent stable column names that survive row insertions and deletions, which plain A1-notation ranges do not.
Can the agent read formulas, or only their calculated values?
The agent reads cell values as evaluated results, not raw formula strings. If cell B5 contains =SUM(B1:B4) and evaluates to 1200, the agent sees 1200. This is intentional — downstream systems expect concrete values, not formula syntax. If you need the formula text itself for auditing, use the Get Cells in Range action immediately after a calculation run and log the output separately.
How do I avoid trigger loops when my agent both reads and writes to the same worksheet?
Use two concrete safeguards. First, scope your trigger to a specific input range (e.g. column A of the DataInput sheet) and scope your agent's writes to a separate output range (e.g. column C onward) — a write to column C never retriggers a column-A row trigger. Second, add a status column the agent checks before acting: if the StatusFlag cell already says 'processed', the agent exits immediately. Combining these two patterns eliminates the vast majority of loop scenarios.
What permissions does the Microsoft 365 connection need?
The MCP connection requests Files.ReadWrite for the connected account's OneDrive, which covers reading and writing .xlsx files in any folder the account can access. It does not request Mail, Calendar, or admin-level permissions. If your organisation uses Conditional Access policies or restricts third-party app consent, your IT admin will need to grant the Actionist app permission in Azure Active Directory before the OAuth flow can complete.
Can the agent create a new workbook, or only write to existing ones?
Yes — the Create Workbook action provisions a brand-new .xlsx file in the connected OneDrive, and the Create Worksheet action adds tabs to any existing workbook. You can chain both in a single workflow: create the workbook, add worksheets, then write data to each tab. The resulting file opens natively in Excel Online or the desktop app with no conversion needed.
Are there rate limits I should know about?
Microsoft Graph API (the underlying API for Excel Online) enforces per-application throttling. In practice, agents running sequential actions stay well within limits. Batch operations using Add Row(s) instead of looped individual Add Row calls reduce API calls by 10–50× and are strongly recommended for bulk imports. If you are processing more than a few hundred rows per minute in parallel workflows, add a short pause between batch calls to stay under the Graph throttle ceiling.
What happens if I disconnect the Microsoft account that owns the workbooks?
The connection becomes invalid immediately and any scheduled or triggered workflows that target Excel will fail with an authentication error. Before disconnecting, go to the Apps tab in Actionist and reconnect with the new or replacement account. If the workbook files are in the same OneDrive path under the new account, existing workflows continue without modification. If the files moved to a different drive or folder, update the workbook references in the affected workflow steps.
