In part two I'll go through some more of the Google Apps Script tutorials.
The third Script
The third Script is basically just creating a custom function that uses Google Sheets to convert from Inches to Millimeters, it's not as complex as the script used in the first of the Google Sheets Scripts that was the second of the tutorials that I did in the last part.
The fourth Script
The fourth Script is still pretty basic but it's a little more advanced as it uses a Google Sheets Spreadsheet to send messages to multiple recipients, this could be used to send basic emails to multiple contacts. But in reality I think it's just an example of what you can do with Scripts in Google Sheets.
In the next part of this series I'll go through some more of the tutorials.
