Gridite Alerts watches your Google Sheetst™ cells and sends you a notification when something changes. Pick a cell, set a condition, choose where to send the alert, and you're done.                           
                                                                                                                                                                                                                
You can be notified by email, Slackt™, Discordt™, Microsoft Teamst™, Google Chat™, or any webhook. Each notification includes the alert name, the cell that changed, the old and new values, and a link back to the  spreadsheet.                                                                                                                                                                                                  
                                                                                                                                                                                                                
Alerts run in the background on a scheduled trigger. The sheet doesn't need to be open. A built-in log shows every alert that fired and whether the delivery succeeded.
