Website status monitoring using Google Sheets and Google Apps Script.


Screenshot of the dashboard worksheet in the Website Status Monitoring managing spreadsheet

A Spreadsheet-bound apps script solution to conduct automated status monitoring on websites listed by the user in a Google Sheets management file. A separate status log file in Google Sheets will be created so that users can easily integrate data with BI services such as Google Data Studio. Notifications of changes in website status will be sent to the user’s Gmail. An optional setting to send notifications to Google Chat is available.

Copy Sample Spreadsheet

Copy this sample spreadsheet to your Google Drive by selecting from the menu File > Make a copy.

How to Use


Screenshot of "Google hasn't verified this app" Authorization Users will be asked to authorized the script the first time they execute it. Free Gmail account users should expect to see the Not Verified by Google warning during this authorization process. You will have to agree with authorization to use this solution despite this warning, but please note that the owner of the script is yourself, and that this solution will not send or receive any information to and from any other Google accounts or services outside the Google ecosystem (except for checking the HTTP response codes of the websites that you designated because, well, that’s what it does for status monitoring) unless you explicitly share the spreadsheet.

Worksheet To Do
01_Dashboard Replace the WEBSITE NAME and TARGET URL columns with those of the website(s) that you want to monitor.
90_Spreadsheets Delete everything except the first header row.
99_Options Go over the parameters that you can set for this status monitoring and edit the VALUE items to suit your needs.

Worksheets not listed above can be left alone; they will be updated automatically.

Set Triggers

From the spreadsheet menu, select Web Status > Triggers > Set Status Check Trigger/Set Log Extraction Trigger to set up time-based triggers to conduct automated status checks. The latest results will be shown in the 01_Dashboard worksheet.

Enable Google Chat Notification

Users can optionally enable Google Chat notification that can be used with (or replace) email notifications of changes in website status. Enter the webhook URL of the Google Chat chatroom that you want the notification to be sent to. Steps to obtain this URL is described in the official documentation by Google. The URL should look something like*****/messages?key=*****&token=*****
