Excel
for LuumenAI
Read the workbooks your team already runs on, and append rows with approval
Operations teams keep real state in spreadsheets: on-call rotations, migration checklists, capacity plans, change logs. Luumen connects to Excel over OAuth2 and reads those workbooks directly — ranges, worksheets, tables, charts — so you can ask questions without opening the file. Changes like adding a table row or a new worksheet are previewed first and, by default, wait for your approval.

Questions
Authorize once with OAuth 2.0. Luumen lists the scopes each action needs before you approve the connection, and credentials never appear in the chat.
This connection exposes write actions such as add chart, add sharepoint worksheet, add table, add table column, and more. For connected tools, admins configure which actions may run automatically and which require approval, within the access granted to the user. Review the configured approval policy before enabling write access.
You decide. Actions are granted per agent, skill, and team, and per environment — production is not staging. Read access can be broad while writes stay narrow.
Every call to Excel — read or write, approved or declined — is recorded with the actor, the input, and the result, and can be linked to the ticket or change record.
