Connect Slack to Microsoft Excel
When New Channel fires in Slack, your agent runs Add Table Row in Microsoft Excel. Describe the whole flow and it is built, tested on every scenario and kept running.
What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it.
Build solutions, not workarounds.

Questions
Slack and Microsoft Excel, answered
What can start an automation from Slack?
Any of Slack's 15 triggers in the catalog, including New Channel, New Channel (instant), New Channel Member and New File (instant). Describe the moment in plain language and your agent picks the right one.
What can your agent do in Microsoft Excel when something happens in Slack?
Any of Microsoft Excel's 42 actions, including Create Workbook, Update Chart, Update Chart Legend and Update Range. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Microsoft Excel to Slack?
Microsoft Excel has no triggers in the catalog today, so automations start in Slack. If you need the other direction, ask: your agent reads Microsoft Excel's API documentation and adds it.
Do I have to build a connector for Slack or Microsoft Excel?
No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running.
What happens when something fails?
Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships.
Is there a free plan?
Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
