Sheet Change Slack Notifier.

Watches the A1 ranges you configure and posts to a Slack incoming webhook when a user edits one in the Sheets interface — saying what changed (cell, old → new, editor). Uses an installable onEdit trigger. Programmatic edits and Google Sheets API writes do not trigger notifications. See the pack README for suppression and signing behavior.

Check before you buy

A one-cell edit includes old and new values. Pasting or filling a range reports the range and cell count instead. Editors outside your Google Workspace may appear as “unknown.” Setup also needs a Slack incoming webhook and an installable trigger.
