- Send Emails fires out automated Gmail messages. You drop a list of email addresses and message texts into Google Sheets, and the script will do the rest. Copy and paste the linked code into a new project in the Script Editor, then save the result with File > Save.
- Website Uptime Monitor creates a log of the uptime and downtime of a given URL, which allows you to track your website's load time and know immediately if it goes down. In this case, the script is already embedded inside a Google Sheet, so you simply adapt the parameters (like the URL you want to monitor) and let it run.
- Docs to Markdown will convert a Google Doc into the popular Markdown format that many content management systems require. Again, the developer provided all the code, so you can simply copy and paste it into a blank Scripts Editor project.
- Invoice Generator from SheetGo turns the rows of a Google Sheet into invoices. You fill the spreadsheet's cells with data like company name, address, and payment amount; then the script places that information in a standard PDF template. If you look over the code, you'll find that it isn't too difficult to parse—variables like "client_name" are easily understandable—which means you can start tweaking the lines to better suit your invoicing needs.
