Capture important decisions before they get buried
When your team makes a decision in Slack, turn the key details into a worksheet row so the record does not depend on someone remembering later.
Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Action
Write Range to Excel
Tool to write values to a cell range in an Excel worksheet. Use when you need to programmatically update worksheet data by specifying a range and a 2D array of values.
Why this helps
Decisions spread across threads are easy to lose when nobody has time to update the tracking sheet.
- Reduce manual copying from channel threads.
- Keep a decision record current while context is fresh.
- Give future-you one worksheet to check.
Setup
Build it in a few focused steps.
- 1Connect Slack and Encodian to Notis once in the portal.
- 2Create an automation prompt naming the decision context, worksheet, range, and information to record in plain language.
- 3Pick the Slack Channel Message Received trigger and choose a channel for run reports.
- 4Test with one real decision and verify the resulting worksheet cells.
Questions about this workflow
Does Encodian create a new workbook?
The action writes values to a cell range in an Excel worksheet; the target workbook and worksheet must be accessible.
How should duplicate decisions be handled?
Tell Notis in the prompt how to recognize an already-recorded decision and test that behavior against the available worksheet context.
