# Introduction

Check Sheet is a Google Sheets app that can send notifications when certain conditions in your spreadsheet are met.

You can use it for almost anything but a few examples are:

* Email a colleague when a task is assigned to them
* Post in a team Slack channel when a sales target is hit
* Send an alert to a Google Chat space when stock levels are low
* Email a client to remind them a payment is due tomorrow
* Update a Microsoft Teams channel when a form submission is received
* Email yourself when a stock price drops below a certain price
